Lab Charge Air Purifier for Allergy

The only thing I can tell you is that they are quiet and you can actually charge your earbuds wireless ones that's the only thing I can tell you right now I haven't had them that long so I can say whether they're really working but my kids tell me that they notice the difference in the air quality so there you go

Seems to be working quite well ... I have three in my living/dining area

silent but wish light were softer. knowing that it's actually working is a little difficult because it's hard to know what isn't there.
