Our all-new, truly portable HEPA air purifier. The small, lightweight QT3 is designed to bring you clean air wherever you go.



A Truly Portable Air Purifier

The QT3 makes clean air accessible, no matter where you go. Even with its small, compact design, the QT3 packs a HEPA filter that captures nearly all pollutants in one pass.

What’s more, the QT3 purifiers contain no ionizer and emit no dangerous ozone, unlike other ‘portable’ purifiers on the market.

Breathe clean air on the go, all at an honest price.

HEPA Filter: Captures Over 95% of Viruses, Bacteria, PM2.5 and Other Dangerous Pollutants

See pollution collect in your filter (instead of your lungs) and enjoy experiencing the cleanest air in the world.

A Portable Air Purifier… And Cooling Fan

We designed the QT3 to also be an on-the-go cooling fan. While a normal fan blows dirty air into your face, the QT3 blows clean, pollution-free air. Experience a fan that uses the cleanest air in the world to cool you down.

Clean Air, No Limits

The QT3 is truly portable. Small enough to be taken for travel, the QT3 allows you to breathe clean air while you are out. Available in both home and travel versions, enjoy clean air on the go at an incredible price.

Small, But Mighty Portable Air Purifier

The QT3 is small enough to be placed on a small table but powerful enough to provide a clean air bubble of 1.2m.

Quiet Operation

At just 29dB of noise on low, the QT3 provides a comfortable environment to sleep in with clean, pollution-free air.

    Very cute and effective. I’ve been using this adorable unit on the go for a few months now – bought it in December and have had no complaints with the filter or the battery. Have been a customer of the brand since 2019, when I bought my first Sqair with them. Their machines are simple and effective. And the cute design always gets compliments! The Delhi team is committed and helped, and resolved my issue with the handle of my unit quickly. My only complaint with the brand is that they should have a better loyalty program on purchases of new units and filters.

    I really liked this product – it came very handy when we went for a road trip. It kept the car air clean esp given the morning smog. We were worried as we were traveling with a small baby and they need clean air which our cities seldom provide. It gave me the satisfaction and peace of mind that we have a purifier with us should we be in any poor air quality locations. It works and looks exactly as per description. Worked well, can last for 4+ hours with a charge at night. No complaints. It’s compact (really!), light weight, and meets expectations.

    I was very excited to receive my qt3 few days ago. I loved the compact and beautiful design. Sturdy body and elegant looks. It is small and handy to carry it anywhere. Be it restaurants, car, office. I was worried about filter replacement cost but i was told that it would be nominal within the range of approx 300. So thats good.
    It has a small hepa filter and a small but powerful fan. 3 speed modes help. I would suggest battery version over normal one. As its portability will be best used when it has battery. Though offcourse it can run on powerbank too.
    I hope it cut down my exposure to pollutants a little.
    Battery backup is good and delivers as promised.
    Its a good product and will hope they come out with even more powerful but portable and cheap version.
    Clean air shldnt be luxury. Thanks to smart air for making it possible.

    Got my unit few days ago. Had been waiting for it since it was announced few months ago. I got it for use in my car and it has been working great. This purifier might be tiny, but it is more than enough for the space inside my hatchback. Real test would be in November, but I am already using it while driving around and I can notice the improvement in air quality as I drive. I like that this is a pure HEPA based purifier with a simple design and provides me with the option to carry it with me and use it without access to a power source. Of course, it also works great with a power bank in case you run out of battery charge or have the Home version. Love it.
