The ORIGINAL Filter Restriction Indicator

  • What We Do

    Engineered Products Co. has designed, manufactured, and improved Filter Minder® filter monitoring devices for over thirty-five years. Our product line has expanded to include a full and exceptionally high quality line of filter monitors, including indicators, switches, and sensors. The Filter Minder® can be found on a wide variety of applications throughout the world, including automotive, truck, construction, agriculture, compressors, blowers, hydraulics, lawn and garden, and irrigation industries... or any industry that uses a filter.
  • Myth vs Fact

    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, 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!
  • Private Labels

    The Filter Minder® can be private labeled with your company name, logo, and part number along with your color preference. The text can be printed so that it is readable with the Filter Minder® mounted in a specific location or orientation (with the reset pointing up or down). For high volume annual requirements, there are no price penalties. There is a one-time artwork and design charge for each specific label.
  • Don't Overservice

    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.
