Air circulating throughout the ventilation ducts contain countless contaminants including allergy triggers that you cannot see, but show up as black soot on the wall area surrounding the air intake vents.
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 underneath any vent register.
Permatron Register filters are made in the USA. Permatron has been an air filtration manufacturer since 1957.
The PreVent® synthetic polyester is manufactured by Permatron in Illinois. The filters are cut to size and packaged at the Illinois plant.
