What's behind our air filter Ratings?

Experts at our National Testing and Research Center tested 12 models in air filters to see which ones perform best.
We look for:
  • Overall score
    Overall score is mainly how well models removed dust and smoke from a test chamber, plus airflow resistance.
  • Dust/pollen/smoke removal (high)
    Dust/pollen/smoke removal is how well a model cleared air of fine clay dust and cigarette smoke when operating at its highest speed. A model that scores well for dust removal should perform comparably for pollen.
  • Dust/pollen/smoke removal (low)
    Dust/pollen/smoke removal is how well a model cleared air of fine clay dust and cigarette smoke when operating at its lowest speed. A model that scores well for dust removal should perform comparably for pollen.
  • Airflow resistance
    Airflow resistance reflects how freely air passed through the unit.
  • Annual cost
    Annual cost is estimated based on continuous operation.
  • Thickness
    Thickness in inches.
