# Medical-Grade Air Purifier UAE: Sizing & Model Guide > How to choose a medical-grade air purifier in the UAE: H13 and H14 HEPA explained, air changes per hour, room sizing, and where each MedicAir model fits. **Canonical HTML page:** https://www.protechnology.ae/medical-grade-air-purifiers-uae **Source:** PRO TECHnology Co. L.L.C., Dubai, United Arab Emirates --- Air Quality Solutions · Buyer’s guide # Medical-Grade Air Purifiers in the UAE: How to Choose and Size the Right System Published 16 September 2026 · PRO TECHnology Air Quality Solutions Most air purifier guides are written for a bedroom. They assume square feet, eight-foot ceilings and a single occupant. If you are specifying equipment for a clinic, a ward, a hotel floor or an office fit-out in the UAE, almost none of that transfers. This guide covers what actually decides the specification: what filter grades really mean under the European standard, how to size a unit from room volume in metric, what air change rates are genuinely required here versus merely recommended, and where the three MedicAir models fit. ## The short answer - **Size from room volume, not floor area.** Required clean air (m³/h) = room volume (m³) × your target air changes per hour. Ceiling height changes the answer. - **“Medical-grade” is a marketing phrase, not a legal class.** What matters is the filter grade under EN 1822, whether the filter is properly sealed in the machine, and what the manufacturer has actually tested. - **H13 and H14 are not “99.97% at 0.3 microns”.** That is the US convention. Under EN 1822, H13 is ≥99.95% and H14 ≥99.995%, measured at the most penetrating particle size. - **A rated airflow figure is not clean air delivery.** Never size a room by dividing its volume into a purifier’s maximum airflow number. - **Portable purification supplements ventilation. It does not replace it**. No UAE rule we found requires a portable purifier in any building, but real duties do sit on the building: Dubai’s healthcare ventilation rules are HVAC design rules, and Al Sa’fat requires air-conditioned buildings to carry permanent filters of at least MERV 8. - **MedicAir publishes three models**: [Pro Mini](https://www.protechnology.ae/medicair-pro-mini-air-purifier-uae) 400 m³/h (H14), [Pro](https://www.protechnology.ae/medicair-pro-air-purifier-uae) 605 m³/h (H13), [Pro Max](https://www.protechnology.ae/medicair-pro-max-air-purifier-uae) 1,500 m³/h (H14), all with activated carbon and UV. Full specifications are on the [MedicAir brand page](https://www.protechnology.ae/medicair-air-purifiers-uae). ## What does “medical-grade” actually mean? It has no legal or regulatory definition. Any manufacturer can print it on a box, and in this market many do. The phrase appears on UAE listings for consumer units with night lights. So it is worth being concrete about what a professional buyer should actually be checking. - **Filter grade under a stated standard**: EN 1822 (or its international equivalent ISO 29463), not an unattributed percentage. - **How the filter is sealed into the machine.** An H14 filter in a poorly sealed housing lets air bypass the medium. System performance is not the same as filter performance. - **A gas-phase stage** (activated carbon), because HEPA captures particles and does nothing for gases, VOCs or odours. - **What has actually been tested, by whom, and against what.** A percentage with no test method behind it is not a specification. - **Whether the unit can run continuously at a speed people will tolerate**, because a purifier that gets switched off for noise delivers nothing. ### H13 vs H14 HEPA, correctly This is where most published comparisons go wrong, including the page currently ranking highest for the question. They describe H13 as “99.97% at 0.3 microns”. That figure belongs to the US convention for HEPA, and it is not how H13 and H14 are defined. Under [EN 1822](https://airfiltration.mann-hummel.com/en-uk/insights/filter-classification/din-en-1822.html), HEPA grades are measured at the **most penetrating particle size** (MPPS): the particle size a filter is worst at catching, typically around 0.12 to 0.25 µm, not a fixed 0.3 µm. On that basis: - **H13**: at least **99.95%** efficiency at MPPS - **H14**: at least **99.995%** efficiency at MPPS The distinction matters in this region because it is the convention the local rules use. Dubai Health Authority’s engineering guidelines specify operating-room filtration as “99.995% MPPS as per EN 1822”, the European convention, not the American one. If you are writing a specification for a Dubai healthcare project, quoting a 0.3-micron figure is quoting the wrong standard. ### Why a higher grade is not automatically the right answer H14 is the finer filter, but finer media is denser media, and denser media resists airflow more. The practical consequences are a higher pressure drop across the filter, more fan energy to move the same air, and more incentive for any leak path around the filter to become the route of least resistance. That is a real engineering trade-off, not a reason to avoid H14. It is a reason to ask how the filter is sealed and what airflow the machine actually achieves with that filter fitted, rather than treating the grade on its own as the answer. ## How to size an air purifier for a room Two numbers decide everything: the volume of the room, and how many times an hour you want that volume worth of clean air delivered into it. ### The arithmetic **Room volume (m³) = length × width × ceiling height** **Required clean air (m³/h) = room volume × target air changes per hour** Inverted, to check a unit against a room: **air changes delivered = clean air delivered (m³/h) ÷ room volume (m³)**. That is the whole method. It is also why floor area on its own is useless: two rooms of 40 m² with 2.7 m and 4 m ceilings differ by almost 50% in volume and therefore in the equipment they need. ### A worked example A consulting room measuring 6 m × 5 m with a 3 m ceiling: - Volume = 6 × 5 × 3 = **90 m³** - At a 5 air-changes-per-hour target: 90 × 5 = **450 m³/h of clean air required** - At a 10 air-changes-per-hour target: 90 × 10 = **900 m³/h** Now compare that against the machines. A MedicAir Pro Mini is rated at up to 400 m³/h, already below the 450 figure before any correction, so for this room at 5 ACH you would be looking at a Pro rather than a Pro Mini, or two Pro Minis. At a 10 ACH target the same room needs 900 m³/h, which is beyond a single Pro and points either to a Pro Max or to multiple units. That is how the calculation should drive the decision, and it is why the honest answer to “which model do I need?” is sometimes “more than one”. ### The correction most guides never make: rated airflow is not clean air A purifier’s headline airflow figure is how much air the fan moves. It is not how much *clean* air the machine delivers. The US EPA defines clean air delivery rate as [the product of the removal efficiency for a pollutant and the airflow rate through the cleaner](https://www.epa.gov/indoor-air-quality-iaq/guide-air-cleaners-home), so the two figures are equal only if the machine captured everything on a single pass, which nothing does. Three consequences that matter when you are specifying: - **Performance figures are quoted at maximum fan speed.** AHAM, which owns the test method, states that clean air delivery is measured at the highest fan speed as a uniform condition, and that airflow and clean air delivery should not be confused. At a quieter setting the delivered figure is lower, and often not published at all. - **Noise is part of the calculation, not a footnote.** A unit sized on its maximum-speed figure and then run on low because staff find it intrusive is not delivering the air changes the specification assumed. - **Very large figures fall outside what AHAM can verify, and the threshold is often misquoted.** The current method, ANSI/AHAM AC-1-2020, measures clean air delivery by particle decay in a 28.4 m³ chamber, and its section 2 applies it only to rated figures of **10 to 600 cfm** for smoke and dust (about 1,019 m³/h) and 25 to 450 cfm, about 765 m³/h, for pollen. Those are limits of the chamber and of statistical accuracy, not of any machine. You will still see “765 m³/h” quoted as an absolute ceiling, including in older AHAM consumer material; that is the pollen figure, and the earlier edition’s limit. Two further things follow. A figure above the range is outside what AHAM can verify, but it is not thereby airflow rather than clean air delivery: China’s GB/T 18801-2022 measures clean air delivery up to 2,000 m³/h in an 81 m³ chamber, and IEC 63086-2-1:2024 sets its own limits. And AHAM certification is voluntary, so a machine’s absence from the directory tells you nothing about the machine. The question to ask a supplier is which method produced the figure. **Worth knowing before you compare brochures.** MedicAir’s own materials use both descriptions for the same numbers: its product specification tables label 400 to 1,500 m³/h as “Airflow at Max. Settings”, while its home-page banner describes the same range as a “clean air delivery rate”. Those are two different physical quantities. We use the specification-table wording (maximum airflow) throughout this guide, and we would encourage you to size against measured clean air delivery wherever a manufacturer publishes it. This is a general point about the category rather than a criticism of one brand: the conflation is widespread. Our [guide to choosing an air purifier for dust](https://www.protechnology.ae/air-purifier-for-dust-uae) covers the consumer-side version of the same problem. ## What air change rate should you actually target? This is where a lot of marketing goes wrong, in both directions. Some vendors quote hospital isolation-room figures at people fitting out an office. Others quote a single “healthcare” number as if one figure covered every clinical room. Neither is right, and the difference between the tiers below is the difference between a defensible specification and an expensive guess. *Air change rates by source. Note carefully which column each figure sits in, a requirement, a recommendation and a manufacturer suggestion are not interchangeable. ASHRAE 170 figures are paraphrased from the outpatient tables reproduced in Addendum h to Standard 170-2021, which ASHRAE publishes free of charge.* | Space or setting | Source | Figure | Status | |---|---|---|---| | Operating room | ASHRAE 170, adopted by DHA for Dubai licensing | 20 total air changes per hour, 4 of them outdoor air, with HEPA-grade final filtration | Design requirement | | Procedure room | ASHRAE 170 | 15 total, 3 outdoor | Design requirement | | Airborne infection isolation room | ASHRAE 170 / DHA | 12 total, 2 outdoor, negative pressure, exhausted outdoors | Design requirement | | Protective environment room | ASHRAE 170 / DHA | 12 total, 2 outdoor, positive pressure, HEPA supply | Design requirement | | Emergency department exam room | ASHRAE 170 | 6 total, 2 outdoor | Design requirement | | General examination room | ASHRAE 170 | 2 total, 2 outdoor | Design requirement | | General indoor spaces | US CDC | 5 or more air changes per hour of clean air | Voluntary recommendation | | Healthcare / office / home | MedicAir (manufacturer) | 10 / 5 / 3 air changes per hour | Manufacturer sizing guidance | ### What is actually required in the UAE For healthcare facilities in Dubai, the [DHA Health Facility Guidelines](https://services.dha.gov.ae/tahpi-app/HealthFacilityGuidelines/Guidelines/Index/DHAHFG) are the licensing basis, and their engineering part adopts ASHRAE Standard 170 as the minimum ventilation requirement. Those are real, enforceable numbers, and they are **HVAC design requirements for the building**, not requirements for plug-in equipment. The single most useful figure in that table is the last of the design requirements: a **general examination room is set at just 2 air changes per hour**. That is the same standard that requires 20 in an operating theatre. If a supplier tells you “healthcare needs 10 air changes” as a blanket statement, they are not describing the standard that governs your building. ### What public health bodies recommend The [US CDC](https://www.cdc.gov/air-quality/ventilation/index.html) recommends a target of at least 5 air changes per hour of clean air in general indoor spaces. That is explicitly a voluntary recommendation rather than a requirement, and CDC notes separately that healthcare facilities have their own requirements. It is a sensible planning figure for an office, a meeting room or a hotel space; it is not a substitute for the design standard in a licensed clinical room. ### What the manufacturer suggests MedicAir publishes its own sizing guidance (3 air changes per hour for a home, 5 for an office, 10 for healthcare) alongside a calculator that takes room length, width and height and returns the number of units required. That guidance is useful for a first pass, and we use it as such. It should be labelled for what it is: a manufacturer’s recommendation. It does not trace back to a standards body or a public-health authority, and its healthcare figure is considerably higher than what ASHRAE 170 requires for most outpatient rooms. **One thing a purifier cannot do.** Air changes from a recirculating purifier and air changes from ventilation are not the same thing. A purifier cleans air that is already in the room; it introduces no outdoor air and removes no carbon dioxide. When a standard specifies a proportion of outdoor air (4 of the 20 changes in an operating room, for instance), no amount of recirculating filtration satisfies that part of the requirement. ## MedicAir Pro Mini vs Pro vs Pro Max [MedicAir](https://www.protechnology.ae/medicair-air-purifiers-uae) is a British manufacturer whose units combine HEPA filtration, an activated carbon stage and a UV-C lamp that the manufacturer describes as “safe UV” on the basis that it is designed not to emit ozone. There are three current models. *MedicAir published specifications, plus room volumes derived by simple arithmetic from the rated airflow figure. Those last two columns are a first-pass filter for shortlisting, not a performance guarantee, see the caveat below.* | Model | Maximum airflow | HEPA (EN 1822) | Activated carbon | UV technology | Published sound | Volume at 5 ACH | Volume at 10 ACH | |---|---|---|---|---|---|---|---| | MedicAir Pro Mini | 400 m³/h | H14 | Yes | Yes | 21 dB lowest setting, ≤55 dB(A) max | ~80 m³ | ~40 m³ | | MedicAir Pro | 605 m³/h | H13 | Yes | Yes | 35 to 60 dB by speed | ~121 m³ | ~60 m³ | | MedicAir Pro Max | 1,500 m³/h | H14 | Yes | Yes | 28 to 54 dB | ~300 m³ | ~150 m³ | **How to read the last two columns.** They are the rated airflow divided by 5 and by 10: the largest room each unit could theoretically serve at those air change rates *if* every cubic metre it moved were perfectly clean and perfectly mixed. Neither is true in practice, and the figures are taken at maximum fan speed. Treat them as an upper bound for shortlisting and expect the real-world figure to be lower, particularly if the unit will be run at a quieter setting. **What has been tested independently.** Dr Iyad Al-Attar examined the MedicAir Pro and Pro Max in Kuwait in 2025, a location chosen for high outdoor particulate, VOC and thermal load. The Pro was measured at 98 to 100% removal of particles above 1 micron and 99% below 1 micron, with VOC concentrations above 8,000 ppm reduced to zero in under 30 seconds; the Pro Max at 96 to 100% above 1 micron. Those are particle and gas measurements under test conditions, not a claim about infection, and the reports are [published by the manufacturer](https://medicair.co/blogs/medicair/independent-global-testing-confirms-medicair-s-filtration-excellence). The full evidence record, with what was tested on which model, is on the [MedicAir brand page](https://www.protechnology.ae/medicair-air-purifiers-uae#evidence). ### MedicAir Pro Mini Up to 400 m³/h, H14 filtration, 510 mm tall on a 250 mm base, 5.6 kg and six fan settings in its 2022 revision (the 2024 revision is stated at 410 m³/h and 5 kg). It is the unit for genuinely small rooms: single consultation rooms, treatment rooms, private offices, hotel guest rooms and small waiting areas. Its published filter life is stated inconsistently by the manufacturer (see the maintenance section below). Two figures need care. The manufacturer’s web pages publish a bare “21 dB” with no upper bound, but the user manual supplied with the unit gives a maximum of **≤55 dB(A)**, so the full range is now known. And the capacity figure differs by source: the supplied manual states **up to 400 m³/h as a clean air delivery rate with the H14 filter, ±10%**, while the website lists 410 m³/h as airflow at maximum setting. Both sit inside the manual’s own tolerance. We publish the manual’s figure, because that is the document supplied with the machine sold here; the full reconciliation is on the [Pro Mini page](https://www.protechnology.ae/medicair-pro-mini-air-purifier-uae). ### MedicAir Pro 605 m³/h, H13 filtration, 88 cm tall and 30 cm wide, 14 kg, 35 to 60 dB across its four speeds. The mid unit for larger consultation and treatment rooms, meeting rooms, larger waiting areas and back-of-house spaces. Note that it is specified at H13 while both the smaller and larger models are H14. That is not an oversight to be embarrassed about: H13 is a HEPA grade, it is what ASHRAE-level filtration in most outpatient rooms is built around, and a coarser medium at higher airflow is a legitimate engineering choice. It is worth knowing if a specification you are answering to names H14 explicitly. ### MedicAir Pro Max 1,500 m³/h, H14 filtration, 38 cm base, 29 kg, stated sound range 28 to 54 dB. This is the model for volume: large waiting areas, open-plan offices, hotel function and lobby spaces, gyms, and any room where a single smaller unit would need to run flat out to keep up. Its 1,500 m³/h is a manufacturer-stated capacity, and MedicAir’s own documents label it two different ways: the specification sheet supplied with the unit prints “Effective - CADR 1500m³/h”, while medicair.co lists the same number as airflow at the maximum setting. At 883 cfm it is above the 600 cfm limit of the AHAM method, so it cannot be an AHAM-verified clean air delivery rate, though that alone does not make it airflow, since other standards do measure clean air delivery at this level. For contrast, the Pro’s 605 m³/h is 356 cfm and sits comfortably inside the AHAM range; it simply has not been tested under it, which is a commercial choice rather than a technical limit. No test method is named for it in either document. That does not make the figure wrong; it makes it a specification rather than a verified result, which is worth knowing before it goes into a tender comparison against a competitor quoting a figure measured under a named method. The [Pro Max page](https://www.protechnology.ae/medicair-pro-max-air-purifier-uae) sets out both labels in full. ## Which model suits which application? ### Hospitals The governing document is the building’s ventilation design, not the purifier. Operating theatres, isolation rooms and protective environment rooms have specific pressure relationships, outdoor-air fractions and exhaust routes that a portable unit cannot provide and must not be presented as providing. The easiest wins are the spaces *around* those rooms: waiting areas, corridors, administrative and staff areas, outpatient rooms, and as a temporary measure during construction or a surge. Pro Max for the large open areas, Pro or Pro Mini for individual rooms. Inside the engineered rooms there is a narrower role, and it is worth stating accurately rather than ruling out. ASHRAE Standard 170 expressly permits supplemental recirculating HEPA devices in airborne infection isolation and protective environment rooms to raise the *equivalent* room air exchanges, with the room’s minimum outdoor air changes still required; CDC recommends choosing units that deliver at least 12 equivalent air changes per hour and siting them on the advice of facility engineers, while preferring fixed ducted recirculation to a portable machine. For an operating theatre, CDC’s one recognised use is temporary supplemental cleaning during intubation and extubation of a tuberculosis patient requiring surgery, with the unit switched off during the procedure itself. None of that is a purchase to make from a brochure: in a licensed facility it belongs to the estates team and the infection prevention and control lead. Our [healthcare deployment guide](https://www.protechnology.ae/medical-grade-air-purification-for-hospitals-clinics-healthcare-facilities) sets out the room-by-room position. ### Clinics and dental practices This is the clearest fit. Most clinical outpatient rooms are modest in volume, occupancy turns over frequently, and the ventilation was often designed to a general commercial standard rather than a clinical one. A Pro Mini in a consultation room and a Pro or Pro Max in the waiting area is a common shape. For dental specifically: the DHA’s current infection control guideline for dentistry manages aerosol risk through PPE, high-volume suction and cleaning practice. It sets no air-change or filtration requirement, and no UAE rule requires a purifier in a dental operatory. Air purification here is a supplementary measure a practice may choose, positioned to draw air away from the breathing zone, not a compliance item. Our [healthcare deployment guide](https://www.protechnology.ae/medical-grade-air-purification-for-hospitals-clinics-healthcare-facilities) covers the clinical context in more detail. ### Hotels Two different problems. Guest rooms are small, and the deciding factor is almost always noise at night rather than airflow (our [offices and hotels guide](https://www.protechnology.ae/air-purifier-office-hotel-uae) works through both): a Pro Mini at a low setting. Public areas, lobbies, function rooms and gyms are volume problems and point to the Pro Max. Smoking-permitted areas are a category of their own, because tobacco smoke is both particles and gases; that is covered separately in our [guide to air purification for cigar lounges and smoking rooms](https://www.protechnology.ae/air-purifier-cigar-smoke-cigar-lounges-uae). ### Offices and commercial spaces CDC’s 5 air changes per hour is a reasonable planning target here. Sizing follows the arithmetic above from the actual room volume. The one thing worth measuring first is carbon dioxide: if CO₂ is climbing through the day, the building needs ventilation, and a purifier will not fix it. Our [buying guide for offices and hotels](https://www.protechnology.ae/air-purifier-office-hotel-uae) covers sizing, placement, noise and procurement, and our [guide to measuring indoor air quality in UAE buildings](https://www.protechnology.ae/indoor-air-quality-schools-clinics-uae-guide) covers what to measure and what the numbers mean. ### Large and high-occupancy spaces Above roughly 300 m³ at a 5 ACH target, a single Pro Max is already at its rated ceiling, so plan on multiple units. Distributing several units through a large space also generally outperforms one unit in a corner: air that never reaches the intake never gets cleaned, and a long or subdivided room can leave whole zones effectively untreated no matter what the total airflow number says. ## Portable purification does not replace ventilation or HVAC This needs stating plainly because a great deal of marketing blurs it. Four different jobs: - **Air conditioning** controls temperature. It introduces no outdoor air of itself and removes no pollutants. - **Ventilation** brings in outdoor air and dilutes what has accumulated indoors, including carbon dioxide, which filtration cannot touch. - **Extraction** removes contaminated air from a space and discharges it outside. - **Air purification** filters and recirculates air already in the room. The World Health Organization states the position directly in its ventilation guidance: [air filters do not provide ventilation and do not replace other ventilation methods](https://www.who.int/publications/i/item/9789241547857). A purifier adds cleaning capacity. It adds no fresh air. It is also worth knowing what Dubai’s rules actually say, because it cuts both ways. The [DHA Health Facility Guidelines](https://services.dha.gov.ae/tahpi-app/HealthFacilityGuidelines/Guidelines/Index/DHAHFG) discourage electronic air filters and photocatalytic oxidation air cleaners in healthcare facilities over ozone and its reaction products, and state that where such devices are used they are not a replacement for mechanical filtration but can be considered as aids to better indoor air quality. **That passage applies to part of what is inside these machines, and we would rather say so than imply otherwise.** MedicAir’s own documentation describes a titanium dioxide reaction chamber around the UV-C emitter (the Pro Mini manual lists the combined cartridge as nano hybrid activated carbon, HEPA H14 and a TiO₂ reaction chamber), and a TiO₂ chamber irradiated by UV-C is photocatalytic oxidation. The filtration work in these units is done by the HEPA medium and the carbon layer, which are mechanical stages and are what a specification should name; the UV and TiO₂ stage is an additional treatment, and DHA’s framing of such stages as an aid rather than a replacement is the right way to read it. Published research on photocatalytic oxidation also records partial-oxidation by-products including formaldehyde and acetaldehyde, and the independent report on the MedicAir Pro itself recommends investigating whether the unit generates by-products, a fair question to put to any supplier, including us. The principle stands either way: in a licensed healthcare facility, plug-in equipment supplements the ventilation design and never substitutes for it. ## Placement, noise and actually running the unit A correctly sized purifier in the wrong place, or switched off, delivers nothing. Four things decide whether the specification survives contact with the building: - **Intake and discharge must not be obstructed.** Pushed against a wall, behind a curtain or under a desk, a unit recirculates its own output instead of the room’s air. - **Position relative to people and the source.** In a treatment room the useful position draws air away from the breathing zone rather than across it. - **Noise is a specification input, not an afterthought.** Published sound figures are at the quietest setting and published performance is at the loudest. A unit that has to run at maximum to hit its numbers will be turned down by staff, and a turned-down unit delivers less air than the calculation assumed. This is the single most common reason a paper-compliant installation underperforms, and it is an argument for sizing generously and running at a middle speed rather than buying the smallest unit that technically qualifies. - **Doors and adjacent spaces.** A room with a door propped open all day is not the sealed volume the arithmetic assumed. ## Filter replacement and maintenance Both filter stages consume their capacity in use, and the carbon stage in particular has a finite adsorption capacity: once it is loaded it stops removing odours and VOCs, with no visible sign. MedicAir publishes a filter life of 5,000 hours for the Pro and Pro Max filters, and recommends replacing filters at least once every twelve months even where the unit has not indicated that a change is required. For the Pro Mini its own pages disagree with each other: the product page states 5,000 hours while the dedicated replacement-filter pages state 4,000. Budget against the shorter figure and ask your supplier to confirm it in writing before it goes into a maintenance contract. Those are general figures. Real interval depends on how many hours a day the unit runs, how heavy the particulate and gas load is, and how much outdoor dust the building admits, which in this region is not a trivial factor. Dubai’s healthcare engineering guidelines require sand trap louvers on outdoor air intakes precisely because of local dust conditions, and the same dust reaches the rooms your purifiers sit in. A unit running 12 hours a day in a busy clinic will not hold a residential filter interval. Our [guide to air purifiers and UAE dust](https://www.protechnology.ae/air-purifier-for-dust-uae) covers pre-filter care in more detail. Budget for filters as a running cost from the start, and track the unit’s filter indicator rather than a calendar alone. ## A claim circulating in the UAE market that you should check before repeating While researching this guide we found several UAE indoor-air-quality vendor pages stating that a “Federal Law No. 5 of 2025, Article 33” makes annual indoor air quality testing mandatory for offices, schools and hospitals. We were unable to find that law on the official UAE legislation portal, and Dubai Municipality’s own indoor air quality guideline cites no such federal law. We are not asserting that no relevant legislation exists, only that we could not verify this specific claim, and that several pages repeating it also misstate Dubai Municipality’s published limits. For the record, the [actual Dubai Municipality guideline](https://www.dm.gov.ae/documents/hsd-gu119/) sets carbon dioxide at 800 ppm over 8 hours and PM2.5 at 35 µg/m³ over 24 hours, its certificate is optional rather than mandatory, and it explicitly excludes hospitals and the medical sector from its scope. If a supplier justifies a purchase to you on the basis of a compliance obligation, ask them for the instrument and the article number. It is a fair question, and a supplier who cannot answer it is selling you something other than compliance. ## MedicAir and PRO TECHnology in the UAE PRO TECHnology is a Dubai-based technology company operating since 1998. Its Air Quality Solutions division supplies, installs and supports indoor air quality equipment across the UAE and the wider region, including MedicAir purification, air quality monitoring, and humidity control. What that means practically for a specification: units can be sized against your actual room schedule rather than a coverage claim, seen running before purchase at our [Business Bay showroom](https://www.protechnology.ae/indoor-air-quality-showroom-dubai-business-bay), with replacement cartridges supplied from Dubai. The wider division is described on our [indoor air quality solutions](https://www.protechnology.ae/iaq-solutions) page. ## Frequently asked questions **What is a medical-grade air purifier?** There is no legal definition, it is a marketing phrase. In practice a professional buyer should read it as: a HEPA filter graded under a stated standard such as EN 1822, sealed properly into the machine so air cannot bypass it, an activated carbon stage for gases and odours, and published test results that say what was tested and against what. **What is the difference between H13 and H14 HEPA?** Under EN 1822, H13 captures at least 99.95% and H14 at least 99.995% of particles at the most penetrating particle size, roughly 0.12 to 0.25 microns. They are not defined at 0.3 microns; that figure comes from the US convention and is a common error in online comparisons. H14 is the finer grade, but it also has a higher pressure drop, so system design and filter sealing matter as much as the grade itself. **Does MedicAir use H13 or H14 filtration?** Both, depending on the model. The Pro Mini and Pro Max are specified at H14; the Pro is specified at H13. All three include an activated carbon stage and a UV lamp that MedicAir describes as safe UV. **How do I calculate the air purifier capacity a room needs?** Multiply length by width by ceiling height to get the room volume in cubic metres, then multiply that by your target air changes per hour. The result is the clean air in cubic metres per hour the room needs. A 6 × 5 × 3 m room is 90 m³, so at 5 air changes per hour it needs 450 m³/h. Compare that against the unit's rated airflow, and expect the delivered figure to be lower than the rating. **What does ACH mean?** Air changes per hour, how many times in an hour a volume of air equal to the room's volume is delivered to it. It is the standard way ventilation and air-cleaning capacity are expressed, and it is the reason room volume rather than floor area is the number to work from. **Does UAE regulation require air purifiers in clinics or hospitals?** No UAE rule we found requires a portable or plug-in air purifier in any healthcare setting, and the DHA's dental infection control guideline sets none either. Requirements that do exist are on the building: Dubai Health Authority's Health Facility Guidelines adopt ASHRAE Standard 170 for ventilation, for example a minimum of about 20 air changes per hour in an operating room, and set minimum filtration in the air handling plant at MERV 8 for the first stage and MERV 14 for the final filter, with HEPA in named rooms. Under Al Sa'fat, existing healthcare facilities in Dubai are also among the building types required to have indoor air tested against set limits. We reviewed the Dubai and Abu Dhabi instruments rather than every emirate's, so we put this as what we found. **Can an air purifier replace hospital ventilation or HVAC?** No. A purifier filters and recirculates air already in the room. It introduces no outdoor air, removes no carbon dioxide, and cannot deliver the outdoor-air fraction or the pressure relationships a clinical room's design requires. The World Health Organization states that air filters do not provide ventilation and do not replace other ventilation methods. **Does MedicAir use UV-C, and is it safe?** MedicAir units include a UV-C emitter inside a titanium dioxide reaction chamber, which the manufacturer describes as safe UV on the basis that it is designed not to emit ozone. Two things are worth knowing. First, a TiO2 chamber irradiated by UV-C is photocatalytic oxidation, and DHA's Health Facility Guidelines discourage photocatalytic and electronic air cleaners in healthcare facilities over ozone and its reaction products, stating that where they are used they are not a replacement for mechanical filtration but can be considered as aids to better indoor air quality. That is exactly how we present this stage: the HEPA and carbon stages do the filtration work. Second, the published research on photocatalytic oxidation records partial-oxidation by-products including formaldehyde and acetaldehyde, and the independent report on the MedicAir Pro itself recommends investigating whether the unit generates by-products. Ozone specifically depends on lamp wavelength (254 nm does not generate it, 185 nm does) and MedicAir does not publish the wavelength, nor any CARB certification or UL 2998 zero-ozone validation for these models. So treat the safety characterisation as the manufacturer's, and ask about it. **Can MedicAir help with odours and VOCs?** Yes, that is what the activated carbon stage is for. HEPA captures particles and does nothing for gases, so any purifier expected to deal with odours, solvents, disinfectant smells or VOCs needs a meaningful carbon stage. Carbon has a finite capacity and needs replacing on schedule to keep working. **Which MedicAir suits a hotel guest room, and which suits a large commercial space?** For a guest room the deciding factor is usually night-time noise rather than airflow, which points to the Pro Mini. For lobbies, function rooms, gyms and open-plan offices the deciding factor is volume, which points to the Pro Max. Work it out from the room volume and your target air change rate rather than from floor area. **How often should MedicAir filters be replaced?** MedicAir publishes a 5,000-hour filter life for the Pro Mini filter and recommends replacing filters at least every twelve months even if the unit has not signalled a change. In a heavily used clinical or commercial space with high dust load, expect to be at the shorter end of that. Follow the unit's own filter indicator alongside the calendar. **Can I use more than one air purifier in a large room?** Yes, and in larger or subdivided spaces it is usually better than one large unit. Several distributed units cover the room more evenly (air that never reaches an intake never gets cleaned) and units running at a middle speed are quieter than a single unit at maximum. If the sizing arithmetic gives a figure above one unit's rated airflow, multiple units is the correct answer rather than a compromise. ## ملخص باللغة العربية: أجهزة تنقية الهواء الطبية في الإمارات عبارة «بمواصفات طبية» ليست تصنيفًا قانونيًا، لذا ينبغي للمشتري المحترف أن ينظر إلى ما هو قابل للتحقق: درجة فلتر HEPA وفق معيار EN 1822، وطريقة إحكام تثبيت الفلتر داخل الجهاز، ووجود مرحلة كربون نشط للغازات والروائح. وفق معيار EN 1822 يلتقط فلتر H13 ما لا يقل عن 99.95% ويلتقط H14 ما لا يقل عن 99.995% عند حجم الجسيمات الأصعب التقاطًا، وليس عند 0.3 ميكرون كما يُنشر خطأً في كثير من المقارنات. ولتحديد السعة المطلوبة يُحسب حجم الغرفة بضرب الطول في العرض في ارتفاع السقف، ثم يُضرب الناتج في عدد تغييرات الهواء المستهدفة في الساعة؛ فغرفة بأبعاد 6 × 5 × 3 أمتار حجمها 90 مترًا مكعبًا وتحتاج إلى 450 متر مكعب في الساعة عند خمس تغييرات. وتجدر الإشارة إلى أن معدل التدفق المُعلن ليس معدل الهواء النظيف المُسلَّم فعليًا، وأن الأرقام تُقاس عند أعلى سرعة للمروحة. تقدّم MedicAir ثلاثة طرازات: Pro Mini بتدفق 400 متر مكعب في الساعة وفلتر H14، وPro بتدفق 605 وفلتر H13، وPro Max بتدفق 1500 وفلتر H14، وجميعها تضم كربونًا نشطًا وتقنية أشعة فوق بنفسجية. من المهم التوضيح أن أجهزة التنقية المحمولة تُكمّل التهوية وأنظمة التكييف ولا تحل محلها، ولا توجد لائحة في الإمارات تُلزم باستخدامها في المنشآت الصحية؛ فمتطلبات هيئة الصحة بدبي تتعلق بتصميم أنظمة التهوية في المبنى. يوفّر فريق حلول جودة الهواء لدى بروتكنولوجي في دبي احتساب السعة المناسبة وفق أبعاد الغرف الفعلية، مع التوريد والتركيب والدعم الفني محليًا.

Where a manufacturer publishes conflicting figures, we say so rather than choosing silently. This guide is engineering and procurement guidance, not medical advice. ## Send us the room schedule The fastest way to a defensible specification is to send the rooms rather than ask which model is best. For each space we need: - length, width and ceiling height - what the room is used for, and typical and peak occupancy - daily operating hours - whether it has mechanical ventilation, and any outdoor-air figure if you have it - any air change rate the project or licensing authority has specified Our Air Quality Solutions team will work through the arithmetic, tell you how many units each space needs, and say plainly where purification is not the right answer and the ventilation design has to be addressed instead.
