Expensive air filters give you more surface area to filter particulate matter. All dimensions being equal, a filter with a higher MERV rating and more pleats per inch will have the same or better air flow than the same filter with a lower MERV rating and fewer pleats.
Do premium air filters make a difference?
Yes, in general, the more expensive air filters are more effective, but a single person with no pets and allergies might not need as much filtration as a family of five with three pets and a child with asthma. Also consider how long your air filter will last.
Do expensive air filters restrict airflow?
