The present invention uses a system designed to keep constant monitor of the air filtration unit in a heating, ventilation and air conditioning system (HVAC) and is to be operated independently of the thermostat used to operate the HVAC system. The silicon-based system is connected to the HVAC system between the forced air filter media and the forced air blower.  This solid-state system is designed to be compatible with any HVAC air handling system.

This system is inexpensive to produce and has a low failure rate because it uses solid-state technology.  This concept could be incorporated into other systems further reducing the overall manufacturing cost.

Lastly, the system is user-friendly after the installer completes the initial set-up.  The ease of use will be a major advantage to the consumer that is seeking an easy, inexpensive way to save money and improve their HVAC system efficiency.
