The QT3 Portable Air Purifier is your ideal travel companion, offering clean air wherever you go. Compact yet powerful, this device features an H11 HEPA filter that captures over 95% of viruses including Covid, bacteria, and PM2.5 particles, ensuring you breathe the cleanest air possible. Unlike many other portable purifiers, the QT3 emits no harmful ozone, making it a safe choice for any environment.

With a CADR of 37m³/hour, the QT3 creates a clean air bubble up to 1.2 meters away, and its rechargeable battery provides up to 4 hours of continuous use. It’s perfect for small spaces like hotel rooms, offices, or even your car. The QT3 operates quietly, with noise levels as low as 29dB on low and up to 45dB on high, allowing you to enjoy fresh air without disturbance.

Receive your QT3 in 2–3 business days. Shipping is free on orders over $100, so add an extra set of replacement HEPA filters (you'll be prompted at checkout) and save! Every order is tracked from our Christchurch warehouse to your door.

House Fresh

"One of the best portable air purifiers on the market, with enough battery power for short and medium-haul flights."

"The QT3 purifier contains no ionizers and doesn’t emit dangerous chemicals like ozone."

"We predicted the Smart Air QT3 would be faster than other portable units that we have tested like the PureZone Mini and we were right: the QT3 cleaned our Tesla in 47 minutes."

BreatheSafeAir

"The QT3 can significantly reduce particles directly in front of the device, and this can make it a good layer to add to your protection strategy."

QT Little life saver

Bought 2 of these little QT models to combat air pollution in bedrooms from wood buring fires in the neighborhood. In combination with keeping windows a tiny crack open these are doing a fantastic job at cleaning the air coming in and the air inside already. No more stinky smoke smell. Life saver. Not too noisy, and the led isnt too bright either. Win win.

Thanks for the review! Glad to hear they're helping you have a safe and quiet sleep environment by removing the unpleasant smoke that's so common this time of year :)

Great extra layer of protection

Cute and quiet. Planning on taking this on holiday to a place where the air quality is less good to filter dust and airborne particles in the room.

Sounds like a perfect travel companion! Hope you find it useful 😊

Snappy Little Companion

I road tested my QT3 Air Purifier and took them to Wellington on a short visit. Used them in the hotel lobby and when ordering in a cafe. Gives me extra protection when in unventilated public buildings.

Love the road test! Great to see your QT3 out and about doing its thing. Thanks for sharing!

FAQs

Like many other air purifiers, the filter replacement light comes on after a set number of hours of use. By default it will come on after 800 hours of use. In New Zealand conditions, your filter will typically last longer.

See below to determine when to replace the filter. To reset the filter reminder, hold the filter replacement button for a couple seconds until it flashes.

As well as the replacement HEPA filteryou can purchase online, we have spare straps and buttons for the strap available. Please get in touchif you'd like to order a strap and/or button set!

As the filter slowly fills up with pollutants, you'll see it get discoloured from it's original white. Often it will appear grey or black. If you notice the QT3 doesn't seem to be providing as much clean air as before, have a look at the HEPA filter.

We provide an estimate of a 10 month lifespan based on 4 hours use per day in NZ conditions.

Yes! The QT3 runs on USB-C power, so you can plug it into your car’s USB port or adapter. With its HEPA filter and high clean air output, it can effectively purify the air inside a car cabin - reducing exhaust fumes, pollen, smoke, and other pollutants during your drive. Compact and portable, it’s an easy way to keep your air clean on the road.
