I have this set-up in my bedroom and run it every night. There is a night mode but I actually prefer the medium fan setting because it creates noise which I do like when sleeping. The night mode also shuts off the LED lights on the top. The high fan mode is very loud, too loud for sleeping. It seems to be working well, checked the air filter after 2 months of use and it was still clean. The UV feature I assume is great, there is no way to tell if it is really on besides the LED light indicating so. I do have this on a smart wi-fi plug to program when it comes on and off and when the power is cut and later restored, it resumes to the last state so I don't have to do a thing.

Great design, not loud, nice and small that fit anywhere but it does not cover 300 Sqaure feet

Just took it out of the box. Read the whole little booklet cover to cover. Says dont operate without water, BUT NO WHERE!! IN IT TELLS YOU WHERE THE WATER GOES. And now im reading reviews people cant find filters.. going back n box and back to Aetna Benefits

I like all the features it has but wish it came with 1 hour instead of 2 hour increments for the timer. Otherwise it cleans the air and I can smell fresh air when using it. Large area capacity. I highly recommend it.

The instruction booklet leaves a little to be desired. It does not indicate you have to open the unit and remove the plastic bag the filter is in. Still not sure what the sleep mode does. Other than that I think the unit is working to clean the air.
