Clean air, wherever you go

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.

Frequently Asked Questions

When should I replace the HEPA filters in my Smart Air Purifier?

The HEPA filter lifespan varies for each purifier. You can find the recommended filter replacement time in each of our air purifier manuals. However, lifespan also varies depending on where you use your purifier, how dirty the air is, and how often you turn it on every day. That’s why we make sure to run real-world tests on all our purifiers, and provide a HEPA filter lifespan calculator to help you calculate how often you need to change your HEPA filter for your exact situation.

How do I set or reset the ‘filter reminder’ button?

There are two buttons on the top, one is on/off and the other is a ‘Filter Reminder’ button. This doesn’t mean you need to change your filter, it is simply a reminder to check. Hold the button down for a couple of seconds until the light flashes. This sets (or resets when you change the filter) the counter to zero. After 800 hours, the light will go on to ask you to check. Note the 800 hours is based on China air quality rather than UK air quality (1200 hours) and is also based on top speed. If you run the QT3 in the UK and at a lower speed, it will last longer but we don’t have a formula to work this out. Instead, the filter reminder counter is set for 800 hours as a reminder to ‘check’ your filter rather than ‘replace’ it.

Why do my HEPA filters smell?

The HEPA filter is made of non-toxic PP/PET material. A new filter may have a faint scent from the glue which is also non-toxic. After being used in the purifier for 2-3 days, this scent will fade away. If the filter is left unused for a period of time with no wind passes through, the excessive moisture in the air will aggravate the breeding of bacteria, which produces acidic smell when turning on the model again. In this case, you can turn on the machine and let the wind blow through several times, or put the filter under the sun for a few days. If all the above does not work, it is recommended to replace the filter.

Why not use a higher grade HEPA filter?

Smart Air’s current HEPA filter is selected from more than 20 different pricings and different purification efficiencies after many experiments and comparisons. A higher grade filter with a higher purification efficiency also means lower airflow. Thus, we combined the fan power and effectiveness to select the current filter.

Does Smart Air recycle filters?

For now, we don’t provide recycling service, because there is no proper way to do so. We tried to make the filters as environmentally friendly as possible. For example, we replaced metal frames with biodegradable cardboard. We also make sure to only use certified environmentally friendly glue in our filters, and to reduce the amount of glue without compromising on cleaning efficiency. E.g. for the Blast and Blast Mini filters, when we switched from metal to cardboard frames, we also reduced the total glue used, being even more environmentally friendly!
