KOIOS Air Purifiers for Bedroom Home, H13 True HEPA Filter Air Purifiers for Desktop Office Car Pets with USB Cable, Small Air Cleaner, Night Light, Timer, Remove Smoke, Dust, Odors, Pollen

I chose this air "purifier" for a simple reason: it uses pretty generic air filters. As long as you can get the air filters (and there seems to be plenty of them on Amazon and elsewhere, for reasonable prices), these will work fine, as it is basically a simple fan pumping dirty air through the filter. And that, it does a pretty good job, with multiple levels of fan power (and noise). The size is pretty small, and doesn't look obviously like an air purifier. The lights indicating power level is pretty low-profile. Though one questions why there's a leather-strap / carry handle on the side. It is powered by a USB-C plug drawing less than an amp even at max power. (Power brick and cable NOT included) There is no air quality indicator or fancy features like that, which is why these purifiers are cheap, with the differences mainly in case design. Twist the bottom to reveal the filter compartment. All in all, simple small capacity air purifier for low price, exactly what's asked for.

It’s a great size. It’s quiet. It’s very nice that you can plug it into your car and it works very well. The only con is that you have to turn it on every time you start your car and I forget way too often to do so.

I use this on my desk at work, a large showroom. Size is right for desk, nice and compact. It is difficult to tell how efficient it is but the one problem I feel is the power. I have it on max (3) and it really doesn't blow much air. The small amount of air it generates just goes straight up. Maybe if my office was a small enclosed cubicle, it might suffice, but at this point I don't feel it is actually doing me any good.

Ordered this for my desk at work. Its small but big enough to make my space feel fresh and clean. It's quiet and it's attractive. I use the night light (blue soothing color) to make it look futuristic, lol. I now have other coworkers asking where to get one. I think its perfect for smaller spaces or areas such as a small kitchen without exhaust. It keeps the muggy smells away and also makes the space feel fresher to breath in Easy access to filter for cleaning and not to heavy to haul around, the cloth handle makes it easy to move from space to space. Its also brings a "little" longer than normal USB cord. So you can place it a bit further from the port than usual items. I recommend.

Not worth the money even with a discount code. This worked perfectly for about a year. Then stopped. Recently I got information from Amazon on how to contact the manufacturer. Who said there is a 1 year warranty and how the item is used effects it. True statements. And this was a work horse. It sat on a desk and then just stopped working. So no not worth it for me.
