great for my kids' schools

I bought a pair last year for my kids' classrooms and have been really happy with the balance of volume versus cleaning power. So far, both kids have managed to stay healthy despite multiple COVID exposures at school, so I am glad to have this as one of our layers of protection.

Even my doctor complimented me on it when I brought it to my appointment!

Love this little air purifier

We took this on a recent road trip and used it at all restaurants. It was also helpful in the vehicle when we encountered smoky conditions due to wildfires. Cleans the air well, good battery life. It’s cute too!

Good for travel

Allowed to be carried on Air Canada flight as a personal fan. Easy to clean and replace filter. Like the compartment at the top which can store a mini power bank; would love for the compartment to have opening for cable to stick out. Would love for the depth of the device to be shortened if possible since there is empty space not used.

Best portable air purifier I’ve tried

Love this, great for our baby’s doctor’s appointments and wildfire smoke exposure! Easily fits in the stroller when out and about.

A comforting size.

Cordless comfort for dental/medical appointments, use in car, or any appointment where aerosol filtering is needed.
Convenient size too. I like it👍🏼.

Great portable purifier!

I've only used it a few times in my office, but I've been impressed by its power and effectiveness! It is a little larger than my other purifiers, but covers a wider space and for that I'm grateful.

Perfect little travel filter

Big, for a travel filter, but not too big to hold; very much like the handle and storage compartment for the cord. Wish it came in more colors!

adorable & effective

This is so cute in person, and the noise of the fan is lovely & low - it's not high pitched like most rechargeable filters & fans on the market. I also love that it has a compartment built in to the top that holds the cord & a USB wall charger (note that only the cord is included).

Really like Smart Air S

It got us through the worst of our allergy season in better shape than ever before. And it’s quiet! Also, it’s very easy to install/replace filters. And I like it’s clean, minimalist design. Overall, excellent. We’ll most likely be buying a second one for a different part of the house, come “smoke season” (forest fires this summer).

Enjoying the air purifier!

I've been using it by my desk where I work and at night when I sleep. Definitely helping this allergy season!

Low quality - not what I would expect from your company

The machine's "fit and finish" is terrible. Really not what I would expect, after using your other machines for a few years now.

The feet popped off, the strap popped off, and I've used it for less than a week.

There are gaps around the filter, so the air isnt forced to move through the filter, and instead goes around it.

Leaks air past filter(fixable)

The air leaks around the edge of the filter. In hindsight, I realized you can actually see the gaps in one of the photos on this site (at this time anyway): at the edge of the opening, there is a black section next to the white filter -- this is the gap (and one like it on the other side) that the air leaks out.
I fixed mine by cutting a cardboard mask (from the box it came in) that matches the edge of the front piece on its outside edge, has a hole on the inside narrower than the filter, and a notch in the bottom where the front attaches to the drawer holding the filter.

No need for filters - QT3 doesn’t work

Hefty hidden COD charges upon delivery for a devise that doesn’t work!

Smart design

Works well so far. Love the hatch up to keep charger cable so I don't lose it. Quiet with good battery performance so far. I didn't like that I wasn't told there would be custom fees, however. Custom fees 3/4 of the price of the actual unit.
