What MERV rating is best for home use?
According to the ASHRAE, the best rating for residential HVAC systems is MERV 13. But before you upgrade your filter, make sure your specific system can accommodate that rating. A higher MERV rating often means lower airflow, which can cause the system to work harder—use more energy—to do its job.
Can a furnace filter be too restrictive?
All furnace filters have a MERV rating which indicates filter efficiency. … The makeup of these high-efficiency filters can be too restrictive for the unit, creating a barrier to good airflow. The HVAC system may struggle to pass air through the air filter and expend more energy in its attempts.
Are all MERV 11 filters the same?
No, HVAC air filters differ in quality and dimensions, and some have features that others don’t. In most instances we advise using the filter your HVAC manufacturer recommends pairing with your system. All filters are assigned MERV ratings, which go from 1–20. MERV stands for minimum efficiency reporting value.
