Best Filters for Allergies: How MERV Ratings Affect Air Quality

MERV ratings, or Minimum Efficiency Ratings Value, are numbers assigned to air filters to determine their efficiency when it comes to removing particulates from the air. Higher MERV ratings translate into better, more efficient, filters. These ratings are expressed in numbers from 1 to 20, each responsible for removing various types of allergens.

  • MERV 1-4: Filters with MERV ratings of 1 to 4 are generally capable of removing only large particulates such as carpet fibers, dust mites, pollen, dust, and textiles fibers.

  • MERV 5-8: MERV 5 to 8 filters routinely capture mold spores, hairspray, and even the dust from cement.

  • MERV 9-12: MERV 9 to 12 filters can remove exhaust fumes, lead dust, and some types of bacteria.

  • MERV 13-16: Filters that boast MERV ratings of 13 to 16 can remove tobacco smoke, all types of bacteria, and even the residue left lingering in the air from a sneeze.
