Freedom Air Filters developed a new cabin air filter pre-filter for Freightliner FLD 120, Classic 1988 and new truck models. The pre-filter is designed to keep debris from truck air filters.

The new pre-filter is the third cabin air filter product released this year and Freedom says that new pre-filters are expected to launch in the first quarter of 2015.

Freedom’s pre-filters can catch particles as small as .005 inches, which the company says extends the life of an air filter. They are made of 1/8 inch-thick ABS plastic and are designed to keep out particles of rubber, dirt, sand and grain chaff from the pleats of an air filter element.

They also feature a proprietary polyester mesh with uniform micron openings and are treated with a hydrophobic water repellant process for added protection. Also, pre-filters can be used multiple times because they are easily cleaned with soap and water.
