The QT3 portable HEPA filter protects you from air pollution

Air pollution is a serious environmental and health issue. And it’s hard to escape – even our homes are filled with these dangerous microscopic particles.

The QT3’s HEPA filter effectively traps particles like PM2.5, dust, pet fur, viruses and mould. You won’t have to worry about your allergies or asthma any longer!

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.

Are HEPA filters effective against COVID?

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 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.

How often should I change my QT3 HEPA filter?

We recommend changing the filter after 800 hours of use. The QT3 has a built-in feature to remind you when 800 hours of use have passed.

Can I wash a dirty HEPA filter?

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 QT3 HEPA filter after the maximum hours of use.
