Breathe easier with these Glasfloss Z-Line air filters.

This is a 4-pack of the 20x20x1 size, so you're set for a year if you change them every 3 months.

They're MERV 10 rated, which means they catch a ton of dust, pollen, and other airborne junk without restricting airflow too much.

Made in the USA with pleated synthetic media and an electrostatic charge to grab more particles.

The exact size is 19.5 x 19.5 x 0.875 inches, so they fit most standard furnace and AC returns.
