Awesome product!
I have this plugged in near my cat’s litter box. He is diabetic and his urine has a more intense odor than regular cat urine. This purifier is AMAZING!!  I can barely smell his litter box at all anymore! I only gave it 4 stars for this because at times I can still smell it. Especially when I have the windows open. It does say in the instructions that it doesn’t work as well when the windows are open. That would be the only negative about it for me. Otherwise, so worth it!!
