Can Fans & Filters

The CF Group makes Can Fans, Max Fans, and Can Filters, along with a host of accessories for these products. To match a Can Filter for your size growing environment, use this formula: Length x Width x Height divided by 3. This figure will give you the minimum recommended CFM for your fan. Then match your inline fan to the size filter you need by getting one that's within the range that the Can Filter can operate within.
