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.

The Crane HEPA Air Purifier is compact and lightweight making it possible to move it wherever I need it. The air purifier's 300 square feet of coverage is a perfect fit for me. I really like the three speed settings which give me total control of the level that I want and need. As an allergy sufferer I’m so glad I have this air purifier as a tool to help me deal with my allergies.

Started off by doing smoke test to see how well it purified the room of smoke by placing it in the bathroom (to ref for small/medium room). Filled the bathroom with smoke and left the purifier on the third (highest) fan speed. The purifier took around an hour till the smoke smell started to dissapate. Great little purifier with a sleep mode, but even leaving it on the first fan speed is quiet enough to sleep with. Only gripe is I wish the purifier had a color light to detect the air quality in the room, but learned that their new model comes with that feature. One other small gripe is I wish the device had a handle that made it easier to carry. Filter is reasonably large so it should last a bit with heavy use!
