Smart Air S

Advertised as quiet and it is, removing smells from cooking and it does. The lid had a small dent and they immediately sent a new lid.

Your website picture for this item is the thicker paper filter (with the UP arrow on the side). You have sent the charcoal filter twice to me. I have kept the wrong item one time because I’ll need it in the future, but I returned this last shipment. Please send me a way to order the paper (accordion type, thicker) filter. Thanks. Btw: I love your product—I’ve bought two of them, but I need a way to order the right filter for them.

They're in good shape and rarely for future use.

Really happy to have a portable HEPA filter with good cfm, relatively speaking.

at home I keep it next to the bed. at school I put it right in front of me on my desk. it weighs less than a notepad and fits in my purse.

It's light, easy to carry, includes a compartment to store the charging cord and you can put a wall plug in easily, too. Good air speed. I wish the charge lasted a bit longer but it can be used while charging, so that helps. And it charges up again quickly.

the fan is so quiet and unobtrusive. and i really think the air is cleaner. i notice a difference.

The Smart Air QT3! Is light, well designed and most importantly delivers a much higher clean air delivery rate than other air personal air purifiers I have tried.

I bought this air filter for travel and have used it near the bed in my hotel room. It is small and lightweight, but moves a lot of air.

I love this filter. It works well for school, meetings, and air travel

Gifting Smarter HEPA products has become the new way of telling family and friends "I love you and care about you so please have a breath of fresh air". The QT3 is another addition to my collection of Smarter HEPA products. It is a blessing for those of us that need that extra protection when going to a clinic or boarding a plane. The QT3 is light and the design is so stylish. I definitely recommend this for personal protection and as a gift for loved ones that need to travel or need clean air in unventilated spaces. Thank you Smarter HEPA for bringing this amazing product to market!

I was confused about whether I'm able to press & hold the QT3 Portable Air Purifier filter replacement button for 2 seconds to start & set the filter replacement light when I first start using the unit. The filter replacement indicator does not flash rapidly 3 times to indicate it has been reset. Does this only work after 800 hours & a replacement filter is needed? Otherwise the purifier is cute & seems to function as advertised. Love the travel version & ability to charge it. A slot for space to leave a power cord connected into the top compartment so I'm able to charge from a small power bank & leave it in that compartment is a design improvement I'd like to request.

I'm very pleased with this monitor. Works well and when comparing it to my purple air appears accurate. I plan to download and analyze the data, which is a plus. The battery life is fairly short but it isn't a major inconvenience. I was going to buy a different monitor earlier this year but I'm happy I waited for this one!

I haven’t had it very long, and I feel as if I’m only starting to familiarize myself with it, but I feel that it was a good purchase. Set-up was effortless, and it seems to be working properly, providing all the data that it was advertised to give. I need to learn more about interpreting some of the numbers. It certainly seems responsive to changing conditions – – when I turn on my gas stove I can see PM 2.5, CO2 and tVOC jump!

Very helpful
