HEPA Greenhouse Intake Filter

Keeps insects, bacteria and mold out of grow-rooms & greenhouses! The Organic Air Greenhouse Intake Filter features a superior blend of HEPA fibers that block out 90% of unwanted airborne particles, yet allows air to flow through with little restriction. Organic Air filters can be washed to ensure maximum performance for many years of use.

Available Sizes:
4-inch (Instruction Manual - PDF format)
6-inch (Instruction Manual - PDF format)
8-inch (Instruction Manual - PDF format)
10-inch (Instruction Manual - PDF format)
12-inch (Instruction Manual - PDF format)

Note: HEPA filters need plenty of air flow, it is NOT recommended that you use an 8-inch filter with an 8-inch blower for instance. It would be much more beneficial to use an 8-inch filter with a 10-inch fan.

HEPAs need the air flowing as fast as possible and in order to do this, you should step up the fan or blower size and use a duct reducer (Reducer Ring Kit sold separately) to attach your HEPA filter to the blower. Again, use a larger fan size than the HEPA filter size!
