Glasfloss 20x24x4 MERV 11 Pleated Air Filters – 6-Pack, Electrostatic, Antimicrobial

Breathe easier with these Glasfloss pleated air filters.

Each is 20x24x4 (actual depth 3-3/4 inches) with a MERV 11 rating—great for trapping allergens, dust, mold, pollen, even some bacteria and smoke.

The electrostatic media pulls in particles, and the galvanized steel frame holds its shape.

This 6-pack covers you for over a year if you swap every 3 months.

Made in the USA, antimicrobial and moisture resistant.

Perfect for furnaces or AC units that take 4-inch filters.

Prop 65 warning applies, but that's standard for many filters.
