SIGNIFICANTLY BETTER PROTECTION FROM FIRST FIT TO END OF LIFE*

When your car is operating at peak demand, it inhales thousands of litres of air a minute. Because every drop of that air contains microscopic abrasive and corrosive contaminants, it’s vital that the air filter is fit for purpose right up until the car’s next full service. 

FILTRON air filters are tested and proven to protect under pressure 

• Laboratory tests of filtration efficiency against an equivalent competitor filter proved that our filter offered over 2 times better protection when new, allowing 59% fewer particles to penetrate*, and 4 times better protection at end of life, delivering 75% less penetration*, without compromising airflow​ 
• This means stronger, sustained parts protection right across the service interval.

_{*M+H laboratory test of FILTRON AP 151/5 vs equivalent product from a competitor manufacturer. Initial filtration efficiency test showed FILTRON AP 151/5 allows 59% fewer particles to penetrate the filter medium. Final filtration efficiency test showed FILTRON AP 151/5 allows 75% fewer particles to penetrate the filter medium.}
