The K&N washable, reusable 20 x 30 x 1 HVAC air filter employs pleated synthetic media with a MERV 11 rating to provide effective filtration and good airflow for most residential systems. Its enhanced dust-holding capacity reduces the need for frequent replacements, and simple washing restores performance for continued use. The reusable design lowers long-term costs and environmental impact, and the filter is covered by K&N's limited lifetime warranty.
