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.
PEAK ARRESTANCE: 90%
INITIAL RESISTANCE: 0.10" WG
AIRFLOW RATE: 1200 FPM
Fits great in the spot. We don't really have any things to say yet. It's only been in the furnace a couple days
While the technology is timely I have foound the system is better then regular heat pump systems. It still requires electricity but uses the natural temperature of the ground to regulate the overall temperature. After you get down over 3 feet, the earth's temperature stays at a steady 50 degrees so for heating and cooling it has a very stable temperature reference point. The system is more expensive to install then typical heating and cooling and more so even than heat exchanger systems but works pretty much the same way. The maintenance costs initially are higher too. In the case of filters, having two sets of washable filters is a must. Pull the dirty filter out, install the clean, dry filter and the system is minimally affected by the swap. Clean the old filter and allow it to completely dry and it will be ready for the change out in a month.
The filter I required is a 14x14 and the one I received fits fine. It looks well made and I hope it last a long time. I need other filters and will probably order them at a later date.

The filter was just as they said it would be. Just make sure you measure the space where your filter will go. Each one is a little bit different than the listed size.
