Keeps insects, bacteria and mold out of your grow room! Organic Air HEPA Filters include a superior blend of fibers that block out 90% of unwanted airborne particles, yet allows air to flow through with little restriction. Washable to ensure maximum performance for many years of use.
HEPA filters require maximum air flow to work properly. Therefore, it is NOT recommended that you use a filter and fan combination of the same size. It would be much more beneficial to use a larger fan and a duct reducer to attach the filter (example: use an 8-inch filter with a 10-inch fan).
