Lennox G40DF-24A-045 Air Filter

The actual dimensions of the filter is not really a choice that needs to be made due to the constraint of the availability of room of whoever designed your heating and cooling system. All air filters are made in lots of varieties and specific sizes, depending on your air quality needs and whether anyone suffers from allergies in the home.
Main clues your main filter should be replaced
- The system air filter looks very bad and should be replaced right now
