Breathe easier at home with these Filterbuy MERV 13 air filters. This 2-pack is perfect for keeping your HVAC system, furnace, or AC unit running cleanly and efficiently. The nominal size is 20x25x1 inches, but the actual size is 19.5\ x 24.5\ x 0.75\ – so be sure to check your slot fits that. Why MERV 13? It's a hospital-grade rating that traps a whopping 98% of airborne nasties. We're talking about pollen, pet dander, mold spores, dust, and even bacteria and smoke particles. If you have allergies, asthma, or just want the cleanest air possible, this is the filter for you. It's made with electrostatically charged synthetic media and has 12 pleats per foot to grab more particles without restricting airflow. The frame is tough beverage board with a wire backing, so it won't warp in heat or humidity (handles up to 200°F). Each filter should last about 3 months. Easy to install – just follow the airflow arrow on the frame. Best part? It's 100% made in the USA with recyclable materials. A simple upgrade for a healthier home.
