Description

Stop throwing your money away. Our GEOTHERMAL permanent filters are designed to work with WaterFurnace Geothermal Systems. They feature minimal air resistance and extra strength to accommodate their large size. The pleated design allows for 30% more air flow to reduce resistance. The filter develops an electrostatic charge that acts like a dust and allergen magnet. These filters are drop-in replacements for the expensive disposable filters. No retro-fitting and no electricity needed. You will be impressed with the quality and performance of this great filter. If your size is not listed, please choose the Custom option and enter the size you need in the box. We can make any size in 1/8 inch increments (W and L).

Frequently Asked Questions

Are your filters available in my size?

Yes. Our permanent filters are available in standard and custom sizes. We offer 12 different filter types to fit most needs.

I'm not sure which permanent filter model is best for me?

Give us a call or send us an email. We can help you choose the filters that's best in your application.

Are permanent filters too restrictive?

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.

How long will your filters last?

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.

Do your filters require electricity?

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.
