Yes. Always use the exact size your HVAC unit requires. The wrong size can cause air leaks, lower efficiency and even damage your system.
MERV 11 works well for most homes. Especially if you have allergies or breathing problems. But it can reduce airflow in some units. Always check if your HVAC unit can handle it.
A MERV rating between 8 and 13 is best. It provides good filtration and keeps airflow strong. Higher ratings can slow airflow if your HVAC isn’t built for them.
The wrong size filter can cause gaps that let dust and dirt through. It also strains your HVAC unit, raises energy bills and may lead to breakdowns.
