RECOMMENDED USE

If you know your residential heating and cooling system can handle a higher MERV rating without impacting air flow, a MERV 13 will provide excellent particle removal. To avoid restricted air flow and negative effects on your system's performance, replacing the filter every 3 months will be critical.

Filters rated MERV 13 are often used in hospitals - specifically in surgical rooms - because they can trap tiny particles like bacteria, and airflow isn't compromised thanks to industrial-grade HVAC systems.
