I brought this for my babys room as he was always getting sick.can notice difference in air quality however machine much to loud even on low setting and lights to bright on low to high setting at night...has night mode with no light and quiet but doesn't filter air properly on this setting to low so not to happy with money spent really

Its a good purifier at this price point, but do not expect to beat the market leaders.

I placed this purifier in my kitchen since smoke gets out of control very quickly when I cook on the stove top. I saw the difference right away! I could see the purifier suck in the smoke, and the light air sensor ring go from red to blue quickly. It's also a really nice design and suits my kitchen well. Would recommend to anyone that has the same issue.
