The problem with dirty or clogged filters can be remedied by replacing the filters on a monthly basis, which significantly extends the life and proper functioning of the house heater. When a dirty filter restricts the air flow inside the heater, the machine goes through unnecessary strain to circulate the warm air. As of 2015, most modern heaters feature a hot surface ignition or an intermittent pilot as their ignition system. When either of the two malfunctions, the heater is not able to generate an electric spark or use a resistance heating elements to ignite the burner.
