Who is Uni filter?

Uni Filter Inc. entered the air filtration industry in 1971 with a simple concept, “Let’s design an air filter that works!” The founders of our company chose to use polyurethane foam as the filtration media because its superior dirt capturing abilities. Polyurethane foam had been used a filtration media for many years, but not until Uni filter introduced the patented seamless “Sock”  Filter for the motorcycles and small engines in 1973 did it receive mass acceptance. The dependable High Air Flow Filter launched a product line that now covers virtually all popular motorcycles and ATV’s. Foam filters were in their infancy in the early 1970’s. But in the 1980’s and 90’s their “High Air Flow” and superior filtration abilities made them the choice for every dirt bike and ATV manufacturer worldwide. Many high performance street motorcycles have also made the switch to foam air filters because of the superior performance advantages. Uni Filter’s cutting edge technology, along with this proven superior filter media, is the perfect team to address any filtration concern for the 21^st century.
