I love the quiet mode, hardly know it's on, great when working or sleeping. LIke the light option, can have it on or off. Noticeably less dust ! Will buy another.

This is in a large room in my apartment (400sqft) and 6.5ft ceilings. I am allergic to whatever comes out of the dryer vent in the apartment I live in and this makes a huge difference! The air quality feels different.Pros-I can feel the difference in air quality.-The color changes based on air quality.-The automatic setting will adjust the intensity based on how dirty the air in a room is.-The first couple levels are very quiet.The third level is loud but I can literally feel the air being circulated in my room.-Great value for the money.Cons-The purifier seems to recognize the output of my humidifier as heavily affecting air quality, which makes it hard to use the automatic setting in the winter.

Works very well & it’s quiet. It has a sleep setting but it also has a setting to turn off the lights on any setting. I use this & leave the fan on automatic. It’s quiet enough that the sleep setting isn’t needed.

I have had this for about 2 weeks and it has helped tremendously in my office. I have a lot of books and it can sometimes smell like storage but it has since vanished. There is a sleep mode but the noise is still the same if you have it on the lowest setting. It's not loud all and you can also shut off the lights which is nice. The size of machine is compact and can pretty much fit anywhere.

I have 3 of these in different areas of my house. Waited about 6 months before reviewing to see how they work. Amazed at the amount of dust these trap over time. My allergies while not gone completely are doing better than before. I don't notice it reducing smells much, but definitely helps with dust which was my main concern. The auto detect feature works well. Runs pretty quiet overall.

This is really easy to set up and use. It’s very quiet and works as white noise in the background. I really like that I’m able to turn off the light completely. I use it mainly to eliminate any pet smells. Very happy with it. I have one in the bedroom and one in the living room.

Works as described, very quiet!

Bought this air purifier in December and have been using it since it arrived and I have to say I am very disappointed. I am past the return date so I am stuck with it. I attached pictures showing the dust that has accumulated on top of the air purifier, which really doesn't make me confident is how well it actually works... At best it is an $80 sound machine.
