The Filtersmarts 226826 is an optical sensor system for HVAC dust filters. Filtersmarts provides a positive indication when an air filter is sufficiently clogged that it should be replaced. The sensor illuminates a portion of the dust filter and monitors the light transmitted through the filter. It is powered by a 9 VOLT BATTERY. There is a remote led indicator light included with 21 inches of wire as well as the one built on the unit.
