BioOx Rocks! This must-have enzyme brew, while pricey, has blown away the cigarette odorama from our house in the country. Wife is happy. Dogs are, too. And, needless to say, so am I.
I use my air purifier up in my office, only place I smoke anymore, and no ones the wiser theres an older-fashioned gent in residence.
This product WORKS, as promised.
