Desa REM40 Air Filter
It is suggested the your furnace filter gets replaced every 3 months so as to maintain good airflow in the home. Filters for your Desa REM40 come in a wide array of types and sizes, which depends on your particular demands for clean air and whether anyone suffers from allergies in the home. The actual dimensions of the filter is not a choice that needs to be made but rather a requirement of whoever designed your heating and cooling system.
