How to Choose From This Shortlist
When choosing an HVAC filter, remember that a higher MERV rating is not always better. While MERV 13 traps microscopic sneeze droplets and smoke, it imposes higher static pressure on your blower motor. For most homes, MERV 11 to 12 provides the ideal equilibrium between clean air and equipment longevity.
