Big Blue Air manufactures some of the best ozone generators in the industry, featuring a full line of in-line UV-based generators. These ozone generators are used in conjunction with centrifugal or mixed-flow fans to allow the treated air to come in contact with the UV-producing lamps. Ozone is a great way to control odor and to completely disinfect indoor grow rooms, from small bedrooms to large warehouses, in between production runs. Ozone helps control powdery mildew and mold, as well as deterring insect pests. The folks at Big Blue Air are as nice as can be and passionate about ozone technology. If you ever have pre-sales questions or need support for a product you already purchased, regardless of how long ago, the guys at Big Blue will take care of you - properly.
