More Clean Air, at a Fraction of the Price.

The Sqair gives you the most clean air per dollar of any purifier in the world, and it’s quieter too. On high, it sounds like soft rainfall. This is up to 13 decibels quieter than the hugely popular Xiaomi purifier, yet provides more clean air for a lower price.

Quieter than all major purifiers


Despite small improvements during the COVID-19 lockdown, air quality in all of China’s major cities were still over the WHO limit in 2020. The Sqair’s H12 HEPA filter removes pollutants like PM2.5, dust, and viruses, giving you cleaner air in your home. The activated carbon filter removes harmful chemicals, smoke and odours.


(included in Chemical Warfare pack)



Paint odour


H12 HEPA (99.5%)







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

    I am very happy with this air filter. I purchased two Sqairs, one for my home-based Pilates studio and one for a bedroom. Very easy to assemble and operate, love the size and style, and I love the mission of the company.

    So effective. Have cleared the air after burning some food when cooking and monitored the air quality improvements with my Purple Air monitor (significant improvements with SQAIR). Quickly cleans the air on the highest setting and the fan sound is not too disruptive (though certainly audible on the top setting).

    Great product very happy. Good quality and the design is lovely. Plug isnt a UK plug (it’s usa) but no problem as the filter uses a ‘figure 8’ lead so easy to get a UK figure 8 lead.

    I use a laser egg sensor to check the air pollution and then automatically turn the air filter on when air pollution is high (it’s in the kitchen so fluctuates when cooking). A free IFTT account makes this very simple to setup.

    Only downside – had to pay import duty to import into the UK. Annoying but still cheaper than rival devices. UK import duty was approx £30.

    Very happy with our SQAIR. Bought online and arrived in days to HK. On lowest setting which is enough for house if leave on during the day, is almost silent. Great airflow due to the simply and elegant design. Charcoal and HEPA filters easily accessible for changing. Apart from filtering virus particles with the HEPA filter it has also noticeably helped my daughter’s allergy to dustmites for which we did have to run the (loud) dehumidifier in her room every night. Now we just leave the SQAIR running overnight and she has no coughing since.

    One super happy customer.

    Overall, I’m very pleased with this air purifier (my Chinese wife bought two units for our home in China) and want to thank the ‘Smart Air’ team for all the very useful and important work they do and help they provide regarding improving the quality of the air we breathe. 😀

    I have a low tolerance for noise, but I don’t notice the sound of the lowest setting at all! Number two is also fine for me. I live in a very polluted area and the Squair cleans the air well. Thanks

    Got the SQAIR last week. It’s a great product to have. With this we are at peace knowing that we are breathing clean air indoors. It is worth every paisa (penny).
