PreVent® Wrap-Around Coil Protecting Air Conditioner Filter

Clean Coils + Good Air Flow = Cool Air!

As the air conditioner runs, dirt, leaves, cottonwood and other debris get pulled into the outdoor condensing unit.  This clogs the cooling coil fins.  Clogged fins restrict air flow needed to operate the air conditioner.  As a result, the equipment loses it's cooling capacity.  Electrical costs rise and equipment breaks down early.  The average cost of a new A/C system is $3,500-$4,000 in a 2,000 square foot home.  And the minimum cost to replace a burned out compressor is $1,000.  According to EPA research 0.042" of dirt on an AC coil can reduce its efficiency by 21%.

Permatron's  PATENTED PreVent® Equipment Protection Filter, Model PREVENTWA,  is a washable  woven synthetic fabric media, which draws in and traps airborne particulates. The electrostatic media, enhanced by airflow, needs no electrical connection or system modification. Framed with a sewn-on black vinyl edging, the filter is affixed to the outer perimeter of the air intake fins and held in place by unique elastic bungee cord/hook attachments.  Built with durability in mind, the filter's black polypropylene media is UV protected and contains an inherent electrostatic charge that won't diminish over time.  PreVent® Equipment Protection Filters will stand up to hostile environments including corrosive areas, UV exposure and fluctuating weather conditions.   Filter is easily removed and cleaned by spraying with a mild cleaner and rinsing with water or vacuumed in place by using a shopvac.  Filter is available in three sizes:  25" x 80", 30" x 100", and 38" x 110" and come packaged with (3) 20" bungee cords.

This filter is also available in a one size fits all, cut-to-fit style filter using black PVC coated polyester high abrasion media.  Simply wrap the filter around the AC unit, secure with included bungee cords, and trim off excess filter material with a scissors.
