MERV ratings between 8 and 11 are a good balance. They trap a lot of dust and allergens without blocking airflow too much.
More expensive filters usually last longer and catch more particles. But whether they’re worth it depends on your home and air quality needs.
MERV 11 is a good choice for most homes. It improves air quality without blocking airflow too much.
Honeywell, Filterbuy, and 3M are frequently recommended for their reliable air filter products.
High MERV filters can block more air, which may strain your HVAC system and raise energy bills.
