The Furnace and Air Conditioner Filters We Would Buy
Updated Dec 12, 2022
When you buy through our links, we may earn a small commission at no additional cost to you.
If we were looking to buy a new filter today for our HVAC (heating, ventilation, and air conditioning) system, we’d aim for a medium-efficiency filter with a MERV rating in the 8 to 13 range, which can clean the air throughout your home almost as effectively as a portable air purifier can clean a room.
