Clair Air Purifier vs AIRE: Which Fits Your Room?

Key takeaways

• Clair is a Korean brand. The K2 sold in Singapore uses an H13 True HEPA filter with activated carbon.
• The K2 listing we checked did not mention UV-C, an ioniser or medical-device status. It is a filtration unit.
• AIRE adds active stages after the filter and supplies businesses with documents, sizing and servicing.
• For a home bedroom with no special concern, a Clair is often enough.

What Clair does well

Clair, founded in Korea in 2014, is known for its e2f electrostatic filter technology. The models Singapore retailers list include the K2, which uses an embossed H13 True HEPA filter, a washable pre-filter and activated carbon. The listing we checked shows CARB and ETL certification and ECARF (allergy foundation) certification, with a sleep mode rated at 32 dB.

Those are sensible credentials for a home unit. The listing makes no medical-device claim, and a bedroom does not need one.

Where Clair is harder to buy in Singapore

In our search we did not confirm an official Clair Singapore website or official store; we found Clair units through retailers such as Amazon.sg, OG and BHG. During our check the K2 listing showed as unavailable with no live price. If you need several units, filters on a schedule, or a supplier who can visit the site, check stock and after-sales support before you commit.

What AIRE adds

AIRE's medical range pairs an H13 HEPA filter with UV-C and copper-silver ion stages. In chamber testing, more than 99.99% of the tested airborne pathogens (E. coli, Staphylococcus albus, Influenza A) were eliminated within 60 minutes, against roughly 4 hours 23 minutes for the same organisms to decay passively on a standard HEPA filter. That is a chamber result, not a promise about illness. Procurement documents cover CE, RoHS, ISO 9001 and ISO 14001, and an FDA Class 2 medical device listing held by the manufacturer. See how we verify our claims.

AIRE does not list retail prices. Clinics and businesses buy or rent, and rental includes filters, servicing and two-way delivery. That is less convenient than a checkout button, and we say so.

Side by side

Competitor details are from the Singapore product or retailer pages we checked on 27 September 2026, and may have changed. Brand names belong to their owners; this is our own comparison.

Which should you choose?

Choose a Clair for a home bedroom where the goal is dust, pollen and odour. Choose AIRE when the room is shared by patients or staff, when you need procurement documents, or when you want someone else to handle filters and servicing.

Frequently asked

Is a Clair air purifier good?

For home use, it is a sensible choice. The Clair K2 sold in Singapore uses an H13 True HEPA filter with activated carbon and lists ECARF allergy certification. The listing we checked did not mention UV-C or ion stages, and filtration alone is fine for most bedrooms.

Does Clair have an official store in Singapore?

We did not confirm one in our search on 27 September 2026. Clair units were listed through third-party retailers, and the K2 listing we checked had no live price. Check stock and filter supply before buying several units.

Should a clinic buy a Clair or an AIRE?

A clinic usually needs sizing for each room, procurement documents and scheduled servicing. AIRE is sold on that basis and adds UV-C and ion stages after the H13 filter. For a single home bedroom, a Clair is often enough.
