Breathe easier with these high-quality Filterbuy air filters! This 3-pack of 16x21x1 filters (actual size: 15.5” x 20.5” x 0.75”) fits most standard furnaces, AC units, and heat pumps. Rated MERV 8, they trap up to 90% of dust, pollen, pet dander, mold spores, and other airborne gunk—without restricting airflow.
The electrostatically charged pleated media grabs particles like a magnet, and the sturdy beverage board frame with dual wire backing holds up to heat and moisture better than flimsy cardboard frames. These filters last about three times longer than basic fiberglass ones, saving you money and hassle.
Easy to install: just check the arrow for airflow direction and slide the old one out. Made entirely in the USA with recyclable materials. If the packaging looks different, don’t worry—it’s the same great filter inside. Keep your home’s air clean and your HVAC system running smoothly with regular filter changes!
