Lennox 14ACX-018 Air Filter
It is highly recommended that the filter that filters out particles from your home is replaced for a clean one every 90 days or so as to maintain good airflow throughout the home. The height, length and width of the filter is not really a optional choice but rather a requirement of your HVAC blower system. Air Filters come in a wide array of filtering types which all depends on your personal desire for cleaner air and air handler size requirements.
