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
I haven't installed it, but it looks good and I am happy to know I will not spend money a filter again :D
Have had my washable filter for my Water Furnace geothermal system for about a month now. It is a great fit and seems to be doing the job. I have not had to wash it yet, so I cannot comment on that aspect of it, but it would seem that it is sturdy enough to stand up to the recommended washing procedure. The actual purchase was delayed due to supply issues, but customer service is top notch.
Ordered a 30”x36”x2” filter per WaterFurnace size recommendation. Received what I ordered but is too big for the filter frame holder by 1/4”.
Cannot use as ordered. Will probably have to modify myself. Do not want to pay another $200.00 for a new filter.
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.
