Some early permanent filters were very restrictive and gave the product a bad reputation in some cases. Some HVAC contractors still tell their customers that all permanent filters are bad.

However, not all permanent filters are created equal. Like any type of filter, there is a balance between dust arrestance and air resistance. Our filters have very low air resistance.

Even our most restrictive filters are no more so than a good pleated disposable filter.

With proper maintenance, you can expect your permanent filter to last at least as long as your HVAC unit. Some of our customers have been using their filters for over 15 years and counting.

No. All of our filters are electrostatic. They have special polypropylene media layers that build a natural static charge as air passes through the filter. The charge is broken and the dust is released when the filter is cleaned.
