Certifications, listings and how to verify a claim

The claim you cannot check is the one to be sceptical of

Almost every air purifier brand selling into Singapore's clinics and offices lists a wall of marks on its spec sheet — CE, RoHS, ISO, and increasingly "FDA Class 2". Few buyers have the time or the background to check what any of them actually cover, and fewer suppliers make it easy to verify. That gap is exactly where a loosely worded claim survives. The right response is not to distrust every mark on principle, but to ask what each one specifically certifies, who holds it, and for which product — questions our claims and verification policy answers for AIRE directly, including where we draw the line on what we will not say.

A certificate does not replace sizing

Before any certification question, there is a simpler one: is the unit even sized for the room. Required clean-air delivery rate (CADR, m³/h) equals floor area (m²) × ceiling height (m) × target air changes per hour, and US CDC guidance sets a floor of at least 5 clean-air changes per hour for an occupied space. A fully certified unit that is undersized for its room will not deliver the air-change rate its paperwork implies — the certification describes the unit, not the outcome in your specific room. Our sizing calculator runs that arithmetic before certification even enters the comparison.

What CE, RoHS and ISO actually certify

CE marking confirms a product meets specific EU safety, health and environmental directives — it is a manufacturer's declaration of conformity to defined standards, not a general safety endorsement. RoHS restricts specific hazardous substances in the materials used, addressing what the unit is made of rather than how well it filters. ISO 9001 and ISO 14001 certify the manufacturer's quality and environmental management systems — meaning how consistently the factory operates and documents its processes, not a rating of the finished product's performance. All three are ongoing standards a manufacturer maintains, not a one-time badge earned and then irrelevant. Our guide to CE, RoHS and ISO certification sets out what each one specifically covers, spec sheet line by spec sheet line.

FDA Class 2: a listing, not an approval

This is the certification most often misrepresented, so it is worth stating plainly. An FDA Class 2 medical device listing is a registration: the manufacturer has registered the device with the US FDA under a specific product classification and stated it meets the applicable requirements for that class. It is not the FDA reviewing and approving the device's performance claims, and it is not the FDA testing the unit itself. "FDA approved" is the wrong term for this — and it is the wrong term for every air purifier on the market today, not only AIRE's, because approval in that sense is not how this device category is regulated in the first place. AIRE's units carry an FDA Class 2 medical device listing held by the manufacturer, and we describe it as exactly that, never as an approval or certification of performance. Our guide to what the FDA Class 2 listing actually means goes through the distinction in more detail, including what the listing does and does not tell you about how a unit performs in your room.

What a genuine claim should let you verify

A brochure stating a certification is not the same as being able to check it. A supplier making a genuine claim should be able to produce the document behind it, name who holds it and for which specific product, and show how the test scope matches the claim being made rather than a broader one — our step-by-step guide to verifying a supplier's claims walks through exactly how to ask. The same scrutiny applies to warranty terms: what is covered on a purchased unit, what falls outside it, and how a rental agreement changes the servicing picture instead, which our guide to warranty coverage sets out. If you are comparing AIRE against another brand entirely, our checklist for what a genuine alternative brand should be able to show you lists the documentation to ask for before switching, so the comparison is between two verifiable positions rather than two brochures.

What we will not claim

We will not call an FDA Class 2 listing an approval, and we will not describe any unit as meeting a Singapore health authority approval standard, because that is not how this device category is regulated here. We will not state that certification alone reduces infections, sick days or any other health outcome — a certification describes a component, a material restriction or a management system, not a clinical result. What we will state is the specific list: H13 HEPA specification, CE, RoHS, ISO 9001 and ISO 14001 management system certification, and an FDA Class 2 medical device listing held by the manufacturer, each described for exactly what it covers rather than rounded up into a broader claim.

Next step: put the claim next to your actual room

A certification tells you about the unit; it does not tell you what your specific rooms need. A Clinic Air Report costs S$150 per site visit, covers a minimum of two rooms, and measures every room on site — the report is emailed within two working days, with a sized-right guarantee: if a specified unit does not reach the report's air-change figure once installed, we upgrade or add a unit at no extra cost. From there, our product range and our contact page are the next steps to a quote built on paperwork you can check, not just a spec sheet you have to take on trust.
