3M Filtrete Micro Allergen Defense 16x20x1 Furnace Filter - Best Overall

If you've ever shopped for replacement furnace filters previously, you'll have encountered 3M's Filtrete line at some point. These are the most popular furnace filters on the market for a good reason - they're priced fairly and do a great job to improve your home's air quality by reducing allergens, mold spores, and pollen. These filters are offered in pack sizes of two, four, or six filters, but note that the filters are not individually wrapped, which means they’re exposed to dust and grime if stored improperly before use. Otherwise, these filters go a long way towards helping you breathe easier in your own home.

These filters offer better indoor air quality by trapping pollen, pet dander, lint, debris, and dust in the air to support your furnace, air conditioner, or overall HVAC system. They're rated MERV 8, which strikes a nice balance between capturing 90% of the airborne particles in your home without clogging up and requiring frequent replacement. The pleated filter design is more effective at filtration while simultaneously allowing more airflow, and the frame is reinforced with wire backings to avoid sagging or folding.
