Description

"I can't use a permanent filter because they are rigid and I have to bend my filter to install it."  Problem solved!  The ECO-FLEX filter is designed to bend and flex when necessary but is also rigid enough to stay in place.  Another benefit...because it does not have a metal frame, it is only 5/8 inch thick.  This filter has the same specs as our GOLD frame filter with a polypropylene webbing frame sewn around the edge.  We recommend that the flex filters only be used in applications where a metal filter will not fit.

 

This filter comes in 5/8 inch thickness only.

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.

No electricity is required. 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.

Cleaning is simple and easy. We recommend vacuuming the dust off the filter every month and then backwashing with water every 2-3 months. We also offer an ELECTROSTIC FILTER CLEANER to clean the filter more thoroughly.

While permanent filters have a higher upfront cost, they save money over time. Most customers recoup their investment within 1 year.
