A dirty filter restricts airflow, raises energy bills, and can freeze your evaporator coil.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch4\u003eIs MERV 13 too restrictive for my system?\u003c\/h4\u003e\n\u003cp\u003eMost modern furnaces and air handlers handle MERV 13 without issues.

MERV 11 adds mold spores and pet dander. MERV 13 adds bacteria and smoke particles.
