Geothermal Custom Size Washable, Permanent, Electrostatic Air Filters

Stop throwing your money away.  Our GEOTHERMAL permanent filters are designed to work with WaterFurnace, Bryant, Carrier, ClimateMaster, Bosch, Florida Heat Pump, GeoFinity & others.  It features minimal air resistance and extra strength to accommodate their large size. The filter uses a mill-finished aluminum frame to enclose an electrostatic media pack. The patented media pack design places two layers of polypropylene mesh around one layer of air-laid polyester media, and these layers are surrounded by two layers of expanded metal. The pack is then corrugated which increases the material surface area thereby allowing greater dust holding capacity and efficiency at an exceptional pressure drop. The height of the pack is made to fit firmly inside the frame giving the filter strength and durability. The frame is made with mitered corners and is secured with pop-rivets. The frame has drain holes in three corners.  The pleated design allows for 30% more air flow to reduce resistance.  The filter develops an electrostatic charge that acts like a dust and allergen magnet. These filters are drop-in replacements for the expensive disposable filters. No retro-fitting and no electricity needed. You will be impressed with the quality and performance of this great filter.
