Why Foam is Better.

Uni Filter entered the air filtration industry in 1969 with a simple concept, “Lets design an air filter that works.” And that’s exactly what we did. We chose polyurethane foam as our air filtration medium, instead of paper or gauze, because of it’s superior dirt capturing capabilities and its capacity to be easily cleaned and reused. And the rest is history. Our original “SOCK” and “POD” air filters took the industry by storm and led to the most comprehensive line of foam air filters in the world!

Here’s how a Uni Foam Air Filter works: “Open Cell” Polyurethane Foam is wetted with specially developed filter oil. The “sticky” filter oil is suspended in the path of the dirty air on the strands of the web-like cell structure of the foam. This makes it impossible for dirt to pass through the depth of the filter without sticking to the strands.
As the outer strands become loaded with dirt particles, the wetted strands down stream start trapping dirt, allowing the entire thickness to be utilized. This prevents surface loading or air restriction for 80% of the service life of the air filter element. When the filter is sufficiently dirty, it can be easily washed, re-oiled, and re-used.


Uni Filter products perform their best in the worst of conditions. That’s why Uni has been the chosen air filter of all serious offroaders for decades. In this dirty, dusty environment, air filtration is extremely critical to the performance and protection of the engine. The Uni Air Filter’s ability to hold extreme amounts of dirt and still provide excellent air flow and performance has made Uni Filter the choice of some of the greatest racers of all time, including but not limited to: Ricky Carmicheal, Jeremy McGrath, Chad Reed, James Stewart, Ryan Villopoto, Eli Tomac, Grant Langston, Joe Byrd, Wayne Matlock, Ronnie Renner, Brian Deegan, Robby Gordon, Cameron Steele, Cale Yarborough and many more.

To keep your UNI FILTER performing at it’s best always use UNI FOAM FILTER OIL and UNI FOAM FILTER CLEANER.
