MERV 8-11 gives the best airflow. These filters stop bigger particles while allowing air to move easily. Higher MERV filters can slow airflow if your system is not built for them.
A filter that doesn’t fit can cause air leaks and block airflow. This can make your HVAC work harder and may lead to damage.
High MERV filters catch smaller particles but they can reduce airflow. This may stress your HVAC if it’s not designed for high efficiency filters.
