  • MERV Rating: This represents the efficiency of the filter in capturing particulates. Better filtration is indicated by higher MERV ratings (MERV 8–13 is typical for households).
  • Filter media: This is the substance that makes up the filter (cotton, fiberglass, etc.) and affects the particles that it collects (dust, allergies, etc.).
  • Size: Must fit precisely the size of the air filter slot in your HVAC system.
  • Replacement Schedule: The frequency of filter changes is contingent upon factors such as air quality, MERV rating, and others.
