Description: UNI Filter® NU-4131ST - Two Stage Air Filter for Honda (see fitment below) Uni Filter® entered the air filtration industry in 1971 with a simple concept, Lets design an air filter that works. Uni Filter chose polyurethane foam as Uni Filter air filtration medium, instead of paper or gauze, because of its superior dirt capturing capabilities and its capacity to be easily cleaned and reused. And the rest is history. Uni Filter's 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! Why foam is a better air filtration medium than paper or gauze? The principle of how foam air filters work is simple: "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 downstream 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.
