I needed a vapor barrior under my add on jacuzzi & shower bathroom. I decided to put a clean room in the 4′ space under my bathroom. Tim (owner) came by wih an experienced, straight forward, honest, creative simple solution. 2 years later I have a maintenance free, circulating environment in my bathroom. Price was very reasonable and I would safely recommend The Clean Air Co. in a heart beat. Thank You Tim your a Rock Star! Ren
