Filter Minder® Visual / Mechanical Indicators & Gauges

Filter Minder® Dash Panel Gauge

Air Filter Restriction Monitoring Gauge

Graduated Indication / Dash Panel Mount


How It Works

The Filter Minder® Dash Panel Gauge uses a graduated indicator that monitors engine air filters. The position indicator progressively fills the window as air filter restriction increases, locking at the highest restriction. The air filter should be changed when the position indicator reaches the red zone.

The Filter Minder® should be reset whenever the service indicator is checked to determine air filter restriction or when a new air filter is installed. Push the reset button and the position indicator will return to zero.
