Using only highly porous virgin activated carbon, GrowBright Pure Flow carbon filters eliminate all odors as the air is forced by the millions of open fissures in the packed carbon.

Effective treatment requires the exchange of air in the growing area within a period of 5 minutes. Compute your requirements by multiplying the (length x width x height) of your growing area to obtain the total cubic feet. Divide this number by 5 to determine the proper fan and filter size needed.

For example, if your growing area is 8 feet long by 8 feet wide by 8 feet tall, it contains a total of 512 cubic feet. To treat this area in five minutes, you would need to use a fan with a minimum CFM (cubic feet per minute) rating of approximately 102.
