How We Chose the Best Air Purifier Filter for Apartments

To choose the best air purifier filter for apartments, we compared popular HEPA, carbon, pre-filter and MERV 13 HVAC filters on Amazon by filter type, rated life, fit and owner feedback.

EPA says to match CADR to room size, use activated carbon for gases and choose at least MERV 13 for HVAC filters where the system allows; see the EPA Guide to Air Cleaners in the Home.

Product details in this guide are based on manufacturer specifications and verified owner feedback. Read more on our How We Test page.

Buying Guide: Filters for Small Homes

Keep these points in mind before you buy.

Match CADR to the room

EPA’s sizing chart suggests a CADR of at least 65 for 100 sq ft, 130 for 200 sq ft, 195 for 300 sq ft and 260 for 400 sq ft, based on an 8-foot ceiling.

Renters and HVAC

Many renters cannot change HVAC filters, so a portable purifier with HEPA and carbon is often the practical choice.

Carbon needs mass

EPA says activated carbon filters can be effective for gases if there is a large amount of carbon; there is no widely used rating for gas removal, and CADR covers particles only.

Apartment Air Tips

Cleaner air in small spaces:

• Run the range hood.
• Seal door gaps from hallways.
• Place purifiers away from walls.
• Close windows on bad air days.
