What makes the Sqair special?

As a B-corp social enterprise helping the world breathe clean air, we designed the Sqair because we were tired of the gimmicks and BS from current air purifier companies. The Sqair gives you far more clean air at a fraction of the cost of the purifiers from those “big guys”.

How did we do this? We cut out the fancy marketing gimmicks such as ionisers and photocatalytic filters that science shows can actually make your air worse. We designed the Sqair for performance, not marketing ploys. The Sqair is data-backed and is excellent at one thing: cleaning air. And it does that better than its competition.

One of the most POWERFUL purifiers in its class

Packing a powerful clean air delivery rate (CADR) of 315m³/hr, the Sqair generates more clean air than most of the competition. The Sqair is suitable for spaces up to 40 m² (430 sqft), the size of a one bedroom apartment

One of the QUIETEST purifiers in the market

On high, it sounds like soft rainfall. It is up to 12 decibels quieter than the hugely popular Dyson purifier, yet provides more clean air and costs less

Blows the competition out of the water on both price and effectiveness

The Sqair gives you the most clean air per pound than most of the purifiers in the UK

Like all HEPAs, captures virtually 100% of viruses, bacteria, PM2.5 and other dangerous pollutants

Watch the pollution collect in your filter (instead of your lungs) and enjoy the experience of breathing clean air
Carbon* (optional)

*The carbon filter is an optional add-on in our Chemical Warfare version. Not everyone needs carbon, so we let air-breathers choose whether they want carbon or not

Why do we recommend a HEPA E11 grade filter for the Sqair?

We ran tests for different grades of HEPA filters when designing the Sqair, and we found that the HEPA E11 filter actually produced the best clean air result for the Sqair. If you’d really prefer a higher grade filter, we offer the Sqair with H13 HEPA but we highly recommend the Sqair with a HEPA E11 filter across its full use of applications

* All Smart Air filters are certified to GB13554-2008 (now updated to GB13554-2020) & GBT6165-2008 standards. This is the Chinese equivalent of EN1822 / ISO29463 and is independently tested.

* The GBT 18801 standard recommends replacing HEPA filters after effectiveness drops to 50% of its initial value. The lifespan will vary depending on the pollution levels in your city. We conducted lifespan tests in Beijing. We calculated the UK lifespan from W.H.O. air quality data as a rough guideline for users in the UK.

† The standard Sqair filter is a HEPA E11 (95%). We selected this grade HEPA as it outperformed the higher grades. We offer optional variations of HEPA H13 (99.95%) filter and/or carbon filter in our Chemical Warfare version but note the airflow and CADR will be different:

  • H13 filter: Top CADR 225m³/h, Airflow 520m³/h
  • Carbon filter: Top CADR 190m³/h, Airflow 480m³/h (note if you choose not to replace the carbon filter as you no longer have a need for it, the spec will be as shown in the main table for the HEPA version)

  1. 5 out of 5

    Mair (verified owner)

    Arrived within a few days of ordering. I have a home office where I see clients – so one is placed there and makes the air fresher and hopefully reduces risk of catching airborne viruses etc. The second is placed in my open plan kitchen/dining/sitting area and really helps with clearing cooking smells – and the third is my bedroom where it’s lovely to wake up to fresh, clean air. No gimmicks or flashing lights – just simple 1,2,3 fan settings

    Excellent. Really helps with our daughter’s rhinitis
