This filter material is made of an electrostatic fabric which draws in and traps airborne particles. The electrostatic force is generated by air flow. Dust, pollen and dirt particles are drawn by the electrostatic field. Rinse and reuse.
When mounting the VF-WHB (white) or the VF-BHB (black) on the top of a register it may be necessary to affix the polypropylene mesh with a few drops of super glue or on supply vents, a bead clear silicon caulk.
In homes with vent ducts built into the floors, high amounts of dirt fall into the ventilation system, especially in high foot traffic areas. A way to keep ducts clean is to install PreVent® electrostatic filtration media in the intake vents and return vents. You simply cut-to-fit the media with scissors, and install the filter on top or underneath any vent register.
Permatron Register filters are made in the USA. Permatron has been an air filtration manufacturer since 1957.
