How often should I clean my K&N HVAC filter?

K&N recommends cleaning your HVAC filter every 90 days, or more often if you live in a dusty area or have pets. Regular cleaning ensures optimal airflow and filtration performance.

How do I clean my K&N HVAC filter?

To clean your K&N HVAC filter, simply rinse it with water and let it air dry completely before reinstalling. Do not oil this filter like you would a K&N automotive air filter.

What is a MERV rating?

MERV stands for Minimum Efficiency Reporting Value. It's a scale that measures the efficiency of air filters. Higher MERV ratings mean the filter captures more particles, but can also restrict airflow.
