Lennox G40DF-36A-070 Air Filter

It is suggested the your furnace filter is exchanged for a new one every 90 days or so because the filter can get clogged and may result in poor air flow inside the house. Lennox G40DF-36A-070 filters are made in lots of types and sizes, which depends on your particular choice for how clean you want the air and air handler size requirements. The measurement proportions of the air filter can not be a personal choice but rather a requirement of whoever designed your heating and cooling system.
