Since the cleanliness of all homes are not equal, GeneralAire includes an easy-to-use, easy-to-read gage. The air filter media will load, capturing airborne particulates, raising the gage indicator to the red-zone, letting you know it’s time to change your filter.
Dial Design is easy to read and interpret when filter needs to be changed.
Easy to calibrate for new, clean media. Easy Install.
Built-in filter screen removes dust from sampled ambient air to keep gage clean.
May be mounted remotely up to 10 feet from monitoring location (with extension kit).
