Well it's just as simple as changing your regular, paper air filter.. It just cleans so much better than the paper filter. You just need to hit it with the air hose .. blow out loose dirt and debris.. ( when it looks clean it is !) Just keep using it .. And when it looks a little, too dirty - then just replace it .. You can go a few oil change intervals before it truly requires replacement.. ** All pretty much dependant on how often , and the amount of miles & conditions you are driving .. the big bonus ; it cleans the air intake so much better !

What kind of vehicle do you drive? Jeep Liberty
