Scott the Filter Man says: "You invested a lot of expense into a geothermal system.  One big factor was probably the cost savings.  Then you learned that the filters for these systems cost an arm and a leg.  Even though only about 1% of HVAC systems are geothermal, we sell a lot of these filters every day.  Why?  Because they pay for themselves in about a year, they trap all major allergens and they are environmentally friendly.  Its' a win-win-win.  These specific filters are also designed with low air resistance for geothermal systems."

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 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.  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.
