Nuwave Air Purifiers for Home Large Room Up to 1361 Sq Ft, Portable Air Purifier with H13 True HEPA & Carbon Filter for Allergies Pet Dander Smoke Dust, 18dB Quiet for Bedroom, Energy Star Certified

I liked this portable air purifier for its 3 layers of filtering. The outside fine screen could be cleaned often. The inner filters are simple rectangle, not too expensive to replace. The product's box says it is for filtering air of 500 sq ft, not 1361 Sq Ft. Since I mainly use its lowest, very quiet mode, so I got two for a 11x13ft room, one by the head of a bed, the other by a desk.The purifier's dust sensor is pretty sensitive. When setting at the auto mode, most time the fan runs at the lowest mode. But whenever I'm making the bed, the bed-side purifier will turn into higher fan. The fan will turn lower in a couple of minutes after I finished making the bed. At the meanwhile, the purifier at the desk, about 5-7 feet away, won't sensor the bed making dust, and stays at the lowest fan setting.On the other hand, if I'm vacuuming the room, both purifiers will getting into higher modes to filter the dusts in the air.I can't stand any noise when sleeping. This purifier's lowest mode is so quiet, I can't hear any sound when it is running right next to my head. I really love this quietness feature.

I didn't know how dirty the air was in my home until I bought 1 of these. Works great and made the air in my house even fresher. Love love love it

I like the Air Cleaner It works great in mobile home. I have a 500 sqft mobile home and I have it near the hallway, so it cleans the whole house.

Best air cleaner I’ve ever owned. It’s automatic option to run more or less definitely helps to only use more power when needed. Even at the highest setting the noise level is acceptable for how fast it works to reduce the smell. The price matches what you get.

Luv this air purifier...bought 2 n they do a great job filtering our air...learned all the mode icons on top n esp. the fan speeds...the highest is med. Loud, doesn't bother me but you can choose to lower it. Changing filters are easy, remember to go easy on parts when removing filters, most parts rely on plastic nowadays.

For several things. My bed, my hand, my body to stay warm.

Works well and seems to do the job. There are 4 fan speeds; 1 is very quiet and 2 is okay, but 3 and 4 are too noisy if you are sitting anywhere near this. It has a lot of nice features but the noise is annoying.

So far so good! This is an amazing little purifier. Perfect for a large bedroom. If I had to list one con is the beeping. Oh, the pet lock is another con— you can only prevent unintended operation when the unit is on. The pet lock feature requires you to depress and hold the fan button for one second to lock the panel. The panel is invisible until it’s on. Thus, the fan button is not illuminated when off and can’t be selected. Also, the beeping is pretty loud and beeps on every press of button. But otherwise it’s an amazing unit.
