Lennox OF24-140 Air Filter
It is highly recommended that the air filter gets replaced every 90 days or so as to maintain good airflow through the ducts. Filters exist in many different filtering types depending on your demands for clean air and whether anyone suffers from allergies in the home. Exact measurements of the filter is not a choice you make because of the constraint of your HVAC blower system.
