Select controller and appropriate size sensor bracket for your filter, each sold separately. The patented FilterPulse™ technology shines a light beam through an HVAC air filter and receives the light that passes through the filter. When a new clean filter is inserted, the filter reset is pressed. An initial light measurement is made calibrating the sensor with the starting base-point of the new filter. Later measurements are compared with the initial measurement. The alarm will activate at the user-set trip point indicating the filter needs to be replaced. This calculation method allows the FilterPulse™ to accurately detect the proper replacement threshold on nearly all varieties and brands of filters. Plus, unlike other products, the FilterPulse™ accurately operates regardless of the HVAC blower speed or pressure fluctuations in the system.
