Air pollution is a serious environmental and health issue. Tiny microscopic particles can slip past our body's defences and penetrate deep within our lungs and heart. Air quality in our homes is all the more important during the COVID pandemic.
The Sqair's HEPA filter effectively traps particles like PM2.5, dust, pet fur, viruses and mould, giving you cleaner air in your bedroom. Sleep more easily without worrying about allergies or asthma.
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 Sqair’s H11 HEPA filter can clean 99.5% of above and below 0.3 microns, PM10 and even 0.005 micron particles.
Why H11? We actually found the H11 filter to be more effective than a H12 filter for the Sqair.
The Sqair’s HEPA E12 filter can clean 99.5% of above and below 0.3 microns, PM10 and even 0.005 micron particles.
Why HEPA E12? We actually found the E12 filter to be more effective than a E13 filter for the Sqair.
A common concern is whether HEPA filters can filter viruses like the COVID-19 coronavirus. HEPA filters removes particles greater than or equal to 0.3 microns, but virus particles are smaller. The coronavirus measures 0.06 to 0.14 microns in diameter. Are air purifiers then powerless against viruses?
Actually, HEPA filters actually work great at capturing viruses. This is because a HEPA filter works not like a net, but through a process called diffusion. Learn more about how this works here.
HEPA lifespans are tricky. Purifier companies like to give lifespan numbers without proper reasoning. Clearly, the HEPA filter will not last as long in UK air as compared to Swiss air.
We estimated the lifespan of the Sqair’s HEPA filter using two methods. Based on Beijing data, we recommend up to 1500* hours of use. This is roughly equal to 6 months if you use the purifier 8 hours a day.
* The filter lifespan will vary according to the pollution levels in your location. Using air quality data from the W.H.O., we can estimate that the HEPA lifespan for the UK will be 2300 hours or 9 months. Please use this figure as a guideline only as this is the average across the whole of the UK and London will be more polluted than the Scottish Highlands.
Unfortunately not. We ran experiments to test this and found that washing HEPA filters does not prolong their lifespan. In fact, washing HEPA filters with water actually decreases performance. That’s why we recommend you replace your Sqair HEPA filter after the maximum hours of use.
At £26 for a replacement, the Sqair HEPA filter offers the best prices for clean air.
