Our disposable panel filter can be used as a direct replacement
for filters supplied in original equipment. Convenient to use and easy to replace. Originally designed for light commercial and industrial applications, the Filters Plus Polyester Filter is an excellent choice for use in residential furnace and air conditioning systems. The filter is produced on state-of-the-art production line machinery that compresses a one-piece channel frame onto the media and retainer. The result is a filter of consistent high quality at a competitive price.
