You invested in that geothermal system to save money and now you find out the filters cost an arm and a leg.  Stop throwing your money away.  Our GEOTHERMAL permanent filters are designed to work with WaterFurnace, Bryant, Carrier, ClimateMaster, Bosch, Florida Heat Pump, GeoFinity & others.  They feature minimal air resistance and extra strength to accommodate their large size.  The 5-layers of Polypro with Polyurethane foam media generate 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.  Please note that these filters have a nominal and an exact (or actual) size.  For example, your filter may have 30x36x1 written on it.  However, when you measure the filter you find it is actually 29-1/2 x 35-3/4 x 1 inches.  So, we recommend that you physically measure your current filter and then find that size in the drop-down menu above.  If your size is not listed, please choose the Custom option and enter the size you need in the box. We can make any size in 1/8 inch increments (W and L).  

 PLEASE NOTE:  These filters are extremely popular and production takes about 3 weeks.
