HEPA filters to capture particulate pollution like PM2.5, dust and viruses, and are the key to clean air. The H13 HEPA filter is now available for the Sqair for special applications. IMPORTANT: The H13 filter will result in a slightly lower CADR of 220m³/h, instead of the original 315m³/h, hence we strongly recommend this HEPA grade only if you'd really prefer a H13 HEPA filter.
We create with intention. Our products solve real problems with clean design and honest materials.
We obsess over the details and strive to deliver the best products at the best prices, every time.

Air pollution is a serious environmental and health issue. Tiny microscopic particles can slip past our body's defenses 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 H13 HEPA filter effectively removes 99.97% of harmful pollutants like PM2.5, dust, and viruses. It is important to note, however, that testing has shown the HEPA E12 filter provides the best clean air performance for this air purifier. We recommend that you purchase the HEPA H13 only if you'd really prefer this grade.
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 H13 HEPA filter can clean 99.95% of above and below 0.3 microns, PM10 and even 0.005 micron particles.
This superb efficiency makes it perfect for fast purification of dental clinics and hospital rooms.

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 £30 for a replacement, the Sqair HEPA filter offers the best prices for clean air.
