Lennox OF25-120 Air Filter
Filters for your Lennox OF25-120 exist in many different styles and sizings, depending on your desire for cleaner air and the specific size of filter you need for your system. Professionals in the industry advise that the filter that filters out particles from your home is replaced for a clean one every 3 months so as to maintain good airflow through the ducts. Measurements of the filter is not a choice you make because of the constraint of whoever designed your heating and cooling system.
