These 2-inch filters have very low (0.10 WG) air resistance and work great in Geothermal systems! Our 2-inch permanent filters measure exactly 1-3/4 inch thick. They can be made in ANY CUSTOM LENGTH and HEIGHT in 1/8 inch increments for NO ADDITIONAL COST. Contact us through Amazon after purchase to let us know what size filter you need. These filters are comparable to a MERV 8 filter. They develop their electrostatic charge naturally as air passes through them. They do not have to be plugged in to a power source. Our 2-inch filters contain 5-stages of media and feature a very low 0.10 W.G. air resistance and excellent 90% dust arrestance
