TOSOTAir Purifier with H13 Medical Grade True HEPA Filter, UV Light Sanitizer, Remove up to 99.97% Dust Smoke Mold Pollen, Ideal for Large Room up to 450 sq. ft, Home, Business, Office, School

I absolutely adore my air purifier, if there is any detected particles in the air the air purifier will make you aware of the contaminants in the air. It will continue to run until all contaminants are alleviated from the atmosphere. I Purchased two more of these units! It’s a must buy.

I have a cat, i smoke, i really like to cook on high heat.I needed something extra for my apt to help keep my air clean. this does the job. i keep it next to my desk while i work.

I got this for my office, and while I can’t say for certain how well this thing works, as I don’t have any way of measuring contaminants in the air, i do know that when in automatic mode, it kicks up the fan when I’m cleaning dust, if i blow smoke in my office, and sometimes when i leave the window open, so I can say for sure that the sensor at least works well.The fan itself is very quiet when in the low setting, not silent, but one would probably forget its there if they’re not focusing on it.As for the display and filters, theres a light on top that will supposedly tell you when the filter needs to be changed. This can be pretty safely disregarded, as mine kicked on about 3 months into its use and never turned off again, even after changing the filter and cleaning the inside of the device with a microfiber cloth. The filters work (again, can’t say how well, but they DO work) and pictured you can see a fresh filter—noted by it’s bright sheen from my light—and a 6-month old filter caked in dust. The manufacturer recommends changing the filter, if used constantly, every three months. What they don’t mention is that these filters are very expensive, about $40 per. Personally, I’d say 5-6 months would give you best use for these for your buck.Overall, I’d say its an alright machine, if a bit expensive. A lot of it can be safely ignored, the UV light for instance is probably more for peace of mind rather then actual use since the documentation and this page give inconsistent specs for the light itself ranging from being kind of useful to might as well just shine a flashlight on it and hope. Something to consider if you’re shopping around for an air purifier.

Seems to work well. I run it about 75% of the time and it’s going strong. The filter works great

Changed from 3 to 4 stars. I really like the auto function Not a bad unit itself. But some things to know. The filter is all one peace. The picture makes it look like you can wash pre filter but u can't. And replacement replacement filters are very expensive. If the filters are that expensive I should be able to clean the pre filter to extend filter life and reduce energy. You can vacuum it but I'm a smoker so I like to spray with degreaser to get nicotine n tar off. After this filter is done I will try to do my own with aquarium filter supplies. Not as good as hepa but there are sheets of carbon filter I can cut n fit in and mico floss on top I can just throw away n cut another piece
