Choose Your MERV Rating

Factory Direct Filters offers several different MERV ratings — a measurement of air filter efficiency — for its filters. A higher MERV rating typically means better filtration, but it also increases the filter’s price. Consider choosing a lower MERV rating to balance quality and affordability.
