This little air purifier is just tough. I put it in the kitchen, and within two hours with the fan power on max it's killed off most strong odors from cooking, pets, and kids. Air is very clean and breathable. And after running it for 8 hours it's pretty much thoroughly cleaned the air of the kitchen and the adjacent living room. Not bad at all! And the addition of the dimming light is a nice touch, helps give some light (and aesthetic) in dark rooms. Only downside is that it's completely quiet when you adjust the fan settings on low. But when on max, it's quite noisy. I would still recommend this due to how unexpectedly powerful it is, and how easy it is to set up and move from room to room as you like.
