Filtro de carbón (explosión)

really happy with my purpose. works great as an air purifier and doubles as a fan. will bring it to my work this summer :)

So easy to carry with me into meeting rooms and cars. Feel super comforted by the increased protection afforded by having a true HEPA filter blowing right in my face.

Pleased with my product and even more with the customer service ! Thank you.

i purchased this purifier to lend it out for events in my city and it’s awesome! incredibly powerful & quiet, very sturdy. i love that it has wheels, i only wish it had some handles for easier lifting into my car (it’s heavy and awkward to hold for a weakling with short arms lol). i’m very excited to pass this thing around town and make events in olympia a lil safer!

I love the lil guy! I feel much safer in my office and in the lunch room to have an extra air filter on hand. The compartment on the top is the perfect size for a small portable battery too.

I have had this air purifier for a couple of years. I keep it running in my bedroom because that is where we sleep and so do our large dogs. My hubby went to change the filter on his cpap device and the filter was still white and clean! Thank you Smarter HEPA!

Perfect for using in small offices for counseling. Helps with soundproofing in a great way. Controls are minimalistic and easy disassembled.

love this little purifier and the company was so helpful when i had to replace a part of the filter. small and easy to bring anywhere!!

The QT3 portable air purifier has very good community feedback on social and the hype is well warranted. This air unit is fun to look at, powerful and is easily personified. It’s lightweight, and the rechargeable battery power makes it so convenient to keep running as well as to take on the go if headed to a work meeting or meet-cute at a cafe. It’s a friendly conversation starter if desired but the QT3 is also discreet enough to go unnoticed.

QT3 are a super cute sidekick to travel with if staying in a hotel and don’t have tons of packing space.
There are some interesting consumer posts on the twitterverse that compare and contrast this unit to others and I’m super glad I went for it and started collecting QT3’s.

Yes. I said collect.
The first QT3 I bought was quickly loved with immediate impact when subtly aimed at the spouse with immediate impact on the husbands reduced congestion and snoring. Obviously, I bought a second one.

While some may collect Stanley cups, I prefer the air purification train.

No more weird smells and noises that wake me up in hotel rooms and Air BnBs. This tiny little air purifier is a dream come true. It made a bubble of clean air and white noise around me that made it easy to get good sleep in new spaces. Thank you for making this little beauty!

As a neurodistinct person with smell and sound hypersensitivities, I have tried maaaaany HEPA filters. My search is finally over! Efficient, quiet, beautiful, and effective--I LOVE this product. And SmarterHEPA is a B Corp! Count yourself lucky to have found this gem...I know I do.

I'm so glad I purchased this lil travel hepa! Still masking, and this really increases my need to be careful when I'm out in public. I've taken this to a coffee shop to sit right next to me and am planning to take it to a movie! I can go out again and have the added protection plus my mask to further reduce my risk of contracting illness.

I don't know if I missed it in the product description, but this thing packaged is over 75 lbs?? There was some difficulty getting it up the stairs into the house because of the weight. It was packaged well, there were metal corner inserts in the box to protect the outside of the unit. Corner inserts were dented pretty good but they did their job as the actual unit was perfectly undamaged.

Unit itself is exceptionally well built. Nothing "cheap" about it. No plastic, wheels attached, nothing to set up, just plug it in and turn it on. Relatively quiet, I keep it on the medium setting and it's a light white noise. The highest setting is a bit louder but just like any other stand-alone fan on the max speed. I can't tell yet how well it cleans/circulates the air as it's only been a few days, but the house seems to recover from cooking smells etc faster than before.

Overall very happy with the purchase.

I love this cute little air purifier! Most of my job is outdoors, but I take my lunch in a shared office and haven't felt covid-safe having to unmask with others present. Though this doesn't solve the problem, I do feel much safer each time I sit for lunch with my new lunch buddy. I can adjust how strong the fan blows and the direction to aim it more directly at my face. I will definitely be bringing this on any future flights I take as well!

I just received my product and I’ve been using it everywhere I’ve been. Waiting for when I go onto an airplane and check it out then.
