A page for every room, not a brochure
Most clinics buy a purifier for a room nobody ever measured. The report replaces the guess with a number you can hold us to.
The room, in numbers
Floor area, ceiling height and volume for each room you send us — waiting room, consult rooms, surgery, sterilisation bay, nap room.
The air changes it needs
The air changes per hour that room should run at, with the reason stated — a dental surgery is not a reception desk.
The clean-air delivery required
The CADR in m³/h needed to reach that figure, worked out from your own dimensions.
The unit that meets it
Which AIRE unit, and how many, per room. Where one unit will not reach the number, we say so instead of stretching it.
Time to clear the air
How long an airborne contaminant takes to clear at your current rate versus the recommended one. For aerosol-generating rooms, that difference is chair time.
Buy or rent, both costed
What the recommended set costs to buy outright, and what it costs on serviced rental with filters, parts, preventive visits and two-way delivery included.
The arithmetic, in the open
Two lines of maths decide whether a purifier is right for a room. We show both, so you can check the report against your own measurements — or against any other brand's proposal.
Sizing
Required CADR (m³/h) = floor area (m²) × ceiling height (m) × target air changes per hour
Public-health guidance since the pandemic, including the US CDC, recommends targeting at least 5 air changes per hour of clean air in occupied spaces. Where we assume a ceiling height because you did not send one, the report says so.
Clearance time
Time to clear 99% of an airborne contaminant (minutes) = 276 ÷ air changes per hour
Airborne contaminant decays exponentially once a room is being turned over. The figure below assumes a well-mixed room and counts the purifier's clean-air delivery towards the air-change rate.
| Air changes per hour | Time to clear 99% | What that means in practice |
|---|---|---|
| 2 | 138 minutes | Common in a closed, air-conditioned room with no dedicated clean-air supply |
| 5 | 55 minutes | The CDC's stated minimum for occupied spaces |
| 6 | 46 minutes | Frequently used for treatment and procedure rooms |
| 10 | 28 minutes | Turnover between aerosol-generating appointments |
| 15 | 18 minutes | High-turnover surgery |
These are clearance times for a room, not claims about infection. See how we verify our claims.
Sized right, or we fix it
If a unit we specify does not reach the air-change figure your report gives for that room, we upgrade it or add a unit at no extra cost.
The risk in buying an air purifier was never that the machine is bad. It is that you buy the wrong size for the room and have no way of knowing. That risk is ours now, in writing, because we are the ones doing the arithmetic.
The limits, stated
- It does not promise fewer infections, fewer sick days or any health outcome. No purifier does, and we will never say ours does.
- CADR figures for every unit we quote, ours included, are manufacturer-rated. No brand in this market publishes an independent CADR certificate.
- Clearance times assume a well-mixed room. A partitioned or heavily obstructed room performs worse, and the report says where that applies.
- It is a sizing document, not an inspection or a certification, and it does not replace your own infection-control policy.

About the Air Report
How much does it cost?
Nothing. We ask for two or more rooms so the report is worth producing. For one room, the size calculator gives you the same arithmetic instantly.
Do you need to visit?
No. The report is produced from the dimensions you send. A visit is only arranged later, if you want rooms measured before installation.
How many air changes should a clinic run at?
Public-health guidance since the pandemic, including the US CDC, recommends at least 5 air changes per hour of clean air in occupied spaces. Aerosol-generating rooms are commonly run higher. Your report states the figure used for each room and why.
Does it promise fewer infections?
No. It is ventilation arithmetic — how much clean air a room needs and what delivers it. No air purifier prevents infection or illness, and we will never say ours does.
