This 2-INCH THICK filter features 3-Stages of filtration, high dust holding capacity and low air resistance. These qualities make it a perfect replacement for expensive disposable filters in residential, commercial and geothermal system. Actual thickness is 1-3/4 inches. The actual air resistance rating of 0.12" WG is lower than most disposable filters. Available here in sizes up to 1200 sq inches. (Contact us for sizes over 1200 sq inches.) This filter contains layers of polypropylene that develop an electrostatic charge as air passes through the filter. This charge attracts and holds particulates until it is cleaned. It is a drop-in replacement for your 2 Inch thick disposable filter requiring no electricity or housing retrofitting. The filter can be cleaned by vacuuming or with water every 4-6 weeks.

Overall I am satisfied with the product. At first it made a horrible whistling sound (when the air passed through the outer sides of the metal frame), but I was able to apply weather stripping to help the edges of the frame seal properly, and now it seems to work great.
Fits great, and runs quieter.
They fit perfectly in my system. I like these filters because they are so easy to take care of. I had the same filters in my other ground source heating and cooling system. Will buy nothing else.
Filter is built sturdy and fit perfectly in my geothermal unit. Customer service was very prompt to answer questions about delivery of the filter during the Covid pandemic as well.
Arrived in good condition and fit perfectly. I will have to attach something to pull it out with. Thanks!
