Uni Filter entered the air filtration industry in 1969 with an idea that was simple, yet foundational to the company's mission statement of manufacturing motorcycle air filters that actually work! The Uni Filter engineering team brainstormed and tested a vast number of filter element material candidates until they decided on using polyurethane foam. Polyurethane foam has an advanced capability as an air filter element, as it's very effective at capturing dirt when it is oiled and prepared correctly. It also has the ability to easily be cleaned, reoiled, and reused, which makes it a cost-effective and practical option for people wanting to protect their engines from dirt and debris.

Over the years, Uni Filter has produced and patented the "Sock" and "Pod" air filter element styles for motorcycles and small engines, and by 1973, it was a household method for engine care and protection because of its features. Uni Filter has developed a range of motorcycle Air Filters for the majority of vehicle makes and models available today, and has cemented themselves as a household name in the air filter game in the motorcycle industry.

Through years of testing and real-world application and experience, Uni Filter has proven that they perform their best in the most challenging and worst conditions for decades now. Some of the biggest names in the professional athlete category have all protected their engines with the Uni Filter brand products, making Uni Filter the motorcycle parts choice of countless championship titles.
