Frequently Asked Questions

Yes, air filters need to closely match the size of your HVAC system to ensure proper fit and effective filtration; otherwise, unfiltered air may bypass the filter.

Is MERV 14 too high for residential?

MERV 14 is typically considered too high for most residential systems, as it may restrict airflow and strain the HVAC unit unless the system is specifically designed for it.

MERV 8 to MERV 11 is ideal for balancing good airflow with effective filtration in most home HVAC systems.

Is a MERV 11 filter too restrictive?
