Best system out there gets the stink out
By customer
Biocide worked great on a home where someone had smoked for 15+ years. The smell was overwhelming when you walked in the house. Biocide mitigated the smoke smell effectively.

It really works had a skunk smell in my home and didn't know how to get rid of it tried everything, got tried and Google something and biocide system popped up decided to order it, wasn't sure if it was gonna work and for the price, because it's very expensive and now a days people will try to get you but NO it really works and came very quickly as far as shipping.I WILL recommend to anyone.
