Filtersmarts is a heating, ventilation, and air conditioning (HVAC) dust filter sensor that indicates when your air filter should be replaced.
Filtersmarts shines a light beam though the HVAC dust filter and measures the light that passes through the filter and lets you know when it is time to replace the filter. This saves energy, wear and tear on your HVAC system, and saves you money.
An initial light measurement is made after inserting a clean filter and resetting the sensor.
