Filter Minder® Air Filter Dial Gauge

Air Filter Restriction Gauge

How It Works

As the air filter becomes restricted, the yellow dial on the Filter Minder® Air Filter Dial Gauge rotates and locks at the highest restriction. The filter should be changed when the dial reaches the red zone. Reset by turning the dial counter-clockwise.
