Permatron's patented PreVent® wrap-around central A/C filter is a permanent, washable woven synthetic fabric. Measuring 30 x 100 inches.

Filtration is enhanced by an electrostatic charge generated by airflow that attracts the finest particulate. The filter is affixed to the outer perimeter of the air intake fins and held in place by (3) bungee cords (included). 

Built with durability in mind, the filter's black polypropylene fabric is UV protected and the inherent electrostatic charge won't diminish over time.  PreVent® Equipment Protection Filters are the standard for large commercial systems where improved efficiency results in major savings. PreVent® will stand up to hostile environments including corrosive areas, UV exposure and fluctuating weather conditions. The filter is easily vacuumed in place or removed and washed. Permatron 5 year warranty.

To determine the size of your PreVent® A/C condenser filter, measure your unit from top to bottom. There are three (3) standard heights available 25", 30" and 38". Next measure the length the filter will wrap-around the condenser. The three standard lengths are 80", 100" and 110".

If the height is not an exact match, the filter should be folder under at the bottom. Any excess length can also be folded under at the edges. The length of the bungee cords are 21" and can stretch to 48" and hook anywhere thru the filter.

Installation is simple, just wrap the filter around the condensing unit and attached the three bungee cords.

The filter can be quickly cleaned with a vacuum while in place. Or for a more thorough cleaning, remove the filter and wash with a hose. Spray in a mild cleaner and hose off, spraying at the filters interior side forcing the dirt and debris back out the exterior side.
