These washable, reusable thermal-bonded fiber filters are designed to work with your FAE Fan to keep unwanted spores and other contaminants out of your fruiting chamber. (Thermal bonding uses a heat process to bond fibers together without the use of acrylic resin, so they maintain their shape with no shrinkage when laundered.)

• Filters can be easily attached to 4" duct fan with clamps
• Filters should be cleaned by hand with lukewarm water and sprayed with a 3% hydrogen peroxide solution.
