Tired of flimsy geothermal filters that don't last or are too restrictive? There are 2 main features that make a great washable geothermal filter. First, the large sizes of most geothermal filters require a robust, high quality frame. The frame should hold up for the lifetime of the filter and should also be made from aluminum so it is lightweight. Second, the filter should allow for good airflow. Geothermal systems are more sensitive to air restriction than mainstream HVAC systems. A geothermal filter should have enough dust arrestance to capture all the common particulates and allergens without being too restrictive. Our GEOTHERMAL filters are especially designed with this balance in mind.
In addition, our filters come with an industry-leading lifetime warranty. We have been selling washable air filters for 15 years and we have found the secret to success.
