FilterPulse™ offers an optical filter sensor + control for HVAC systems that notifies when an air filter is dirty and requires replacement. Utilizing its infrared sensing technology, the FilterPulse™ operates independently from air speed fluctuations and pressure changes in the HVAC system which is not possible with pressure sensing instruments.
This technology’s performance enables the FilterPulse™ to be the only device that produces an accurate detection of replacement status on a variety of capacity filters, across all brands, in complex to simple HVAC systems.
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.
