## Description

This filter is exactly measures exactly 15-5/8 x 19-5/8 x 1-3/4 inches.

Why spend $100's per year on replacement filters?

Replace your 2-inch thick disposable filter with a permanent, washable, lifetime-warranty filter. Just remove filter, vacuum or hose off and reinstall. Contractors like to install these systems and then charge $150 - $200 everytime they change the filter. Stop wasting your money! Never buy another filter again.

These 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.

What is the MERV rating on your filter? 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.

These filters contain 5-stages of media and feature a very low 0.10 W.G. air resistance for geothermal systems.  They have an excellent 90% dust arrestance rating.
