Lennox 13HPD-018 Air Filter

It is recommended that the air filter gets replaced every 90 days or so because the filter can get clogged and may result in poor air flow in the home. The actual dimensions of the filter is not really a choice that needs to be made but rather a requirement of your furnace or handler. Air Filters are available in many filtering types which all depends on your personal desire for cleaner air and whether anyone suffers from allergies in the home.
