Roto HEPA Air Purifier for Home Bedroom, H13 True HEPA Filter with Filtration System Cleaner Odor Eliminators, Remove 99.97% Dust Smoke Mold Pollen, 4 Fan Speed with Quiet Auto Mode, White

I got this air purifier for my office space that opens up to the kitchen. It seemed like there was a lot of dust particles in the air lately, you could even see it when a stream of sunlight would come through. The purifier is a little larger than I thought it would be but it still fits on the corner of my desk. It has a large HEPA filter. The purifier has sensors that monitor the air and if you keep it on "auto" it's very quiet mostly using the lowest setting but kicks in automatically to higher speed if it detects something in the air, like smoke or cooking smells or if something kicks up some dust or air. It has 4 speeds with auto using the first 3 and you can manually put it on turbo speed which is a bit noisy but works well if you need to clear the air fast. After using the purifier for a few hours, we could literally see a difference in the air quality....there were no dust particles in beams of sunlight, it was completely clear and the air felt cleaner. We've been using it about a week now and I just ordered a second one for a back room in the house. It's a good value and does a good job.

quiet enough. could use a color changing mode. hopefully the filters are not very expensive and findable when it comes time,and the machine lasts for years.

The noise is very light. Fits well in small spaces. So far so good .

Only had it plugged in for a couple hours. My bf and I can already tell a difference. So happy I bought this. Our allergies have been so bad. I really hope this will help.

What is there not to like? It's quiet, it filters whatever it is irrating my allergies, and it got rid of the stinky damp smell in my room. The fact I can breathe helps me sleep like a baby now. The fact all this only costed me around $30 says I'm making wise choices in my old age.

No as quite as I had hoped but other than that I’m happy with my purchase

Very quiet and super sufficient!

Does it work? I have no idea. I will not lie to you. It turns on and it is very quiet. I did buy replacement filters and it still says it needs a new filter so that's odd. Otherwise, it hasn't given me any grief so to speak but as far as, "effective" we shall never truly know. I have convinced myself that it does and really isn't that all that matters? Of course I would recommend this product because we all need a good air filter in our lives. Unless you live in the country...
