The Filter Minder® filter monitoring device makes it easy for you to tell when it's time to change filters.  

The myth is that an automotive air filter should be changed about every 6,000 miles, or when it "looks dirty."

The fact is that a certain amount of dirt in an air filter actually increases its filtering efficiency by reducing the size of the holes in the filter media which helps stop smaller dirt particles.

This means that instead of a maximum life of 6,000 miles, the typical air filter may actually last anywhere from 60,000 to 100,000 miles!

Air filter restriction is not time or miles dependent.

Mileage of as much as 300,000 to as little as 5,000 miles have been reported when restriction is reached.

It is important to know the highest full load restriction that occurred during the vehicle operation in order to service BEFORE the redline.  

After an element has reached its redline value, it only takes a little more contaminant before high fuel consumption and poor engine operation occurs.  Don't Dust Your Engine!

Filters do not plug based on time or mileage. They plug based on the operating environment of the vehicle.

The Filter Minder® takes the guesswork out of filter maintenance because it doesn't care how dirty the air filter looks or how long it's been installed. It only cares how well the filter is working. When the filter gets restricted, the Filter Minder® will let you know.
