1" filters: every 60-90 days (monthly if you have pets). 4-5" media filters: every 6-12 months. A dirty filter restricts airflow, raises energy bills, and can freeze your evaporator coil.
Most modern furnaces and air handlers handle MERV 13 without issues. Older systems with weak blower motors may need MERV 11 or lower. If you notice reduced airflow after upgrading, step down one MERV level.
MERV 8 catches dust and pollen. MERV 11 adds mold spores and pet dander. MERV 13 adds bacteria and smoke particles. Higher MERV = cleaner air but slightly more airflow resistance.
Yes — install with the arrow pointing toward the blower/furnace (in the direction of airflow). The arrow is printed on the filter frame.
