Twin Air's legendary quality heralds back more then 30 years when stock paper air filters were a big problem for the engine especially in the sandy, gritty soil of The Netherlands. Single foam and paper filters gave riders airflow, but didn't cut it for protection and lasted only 30 minutes in the sand dunes of Holland . Twin Air found the solution to deliver unbeatable performance and protection by producing special laminated Foam air filters and filter accessories. The original typical Paper air filter was consequently replaced by washable Twin Air foam air filters. These Twin Air filters are, when treated with the right filter oil, a perfect product to prevent dirt, grime, sand and water entering the carburettor and giving unbeatable performance.

Now Twin Air is known because of it's superior quality, craftsmanship, supplying and service of foam air filters with a very large distribution network all over the world.

Because of our high quality foam air filters, we also are an Original Equipment Manufacturer for over 10 motorcycle companies; KTM Motorcycles AG, Husaberg Motor AB, Husqvarna, Cagiva, MV Agusta, Vertemati Moto srl, VOR motorcycles, Sherco, Gas Gas Motos sa, CCM Motorcycles limited, MUZ, Metisse, TM.

We also have sponsored many teams such as Team Suzuki, back in the days with their riders Roger de Coster , Sylvain Geboers and Joel Robert . Up and till this moment Team American Suzuki (with team manager Roger de Coster ) with Ricky Carmichael are still using Twin Air filters. Also Team Suzuki Grand Prix (with team manager Sylvain Geboers ) with Joel Smets is still using the very reliable and proven Twin Air filters. Team Cagiva / Husqvarna with Dave Strijbos and Pekka Vehkonen. The KTM riders of the early days, now working as team managers, like Heinz Kinigardner, Kees v.d. Ven and Kurt Nicoll , with there riders Ben Townley and Steve Ramon (just to mention just a few), still favour Twin Air filters and have their riders use them. Remarkable are the many world titles won by father and son, Harrie and Stefan Everts using Twin Air filters. Many world titles were won using Twin Air filters on among others the Honda machines with their riders such as Andre Malherbe, J.M. Bayle, David Thorpe, Eric Geboers, George Jobe, Greg Albertijn, Frederic Bolley . Also Team American Honda with their riders Andrew Short, Jeremy McGrath, Ernesto Fonseca and Travis Preston. Kawasaki Europe with their team manager Jan de Groot , also won many world titles. Think of Sebastian Tortelli and Stefan Everts . Former world champion and present Yamaha team manager Michele Rinaldi , still uses Twin Air filters for his team. Donny Schmit, Andrea Bartolini and Stefan Everts became world champions on Yamaha machines using Twin Air filters.
