This wiki has been updated 5 times since it was first published in November of 2018. If you're worried about your family's respiratory health, then investing in a good air filter for your HVAC system is an absolute must. The selections on this list are designed to fit units requiring 20 x 25 x 5 screens, which are incredibly thick to give you added layers of protection. They can pick dust, germs, pollen, and other debris from the air before they reach your lungs. When users buy our independently chosen editorial picks, we may earn commissions to help fund the Wiki.

Editor's Notes

January 04, 2019:

Before making a purchase, users should understand the difference between "nominal size" and "actual size." Basically, while many options claim to be 20x25x5, the actual dimensions might vary by a few fractions of an inch. Check your existing filter to see what the correct size is for your HVAC unit, and then order one that meets those rather than just blindly assuming the listed dimensions will work.
