The FilterBuy replacement air filter 12x24x1 (actual measurements: 11.38" x 23.38" x 0.75") ensures that your furnace, air conditioner, or HVAC system is circulating the cleanest air possible to help preserve your budget and healthy lifestyle. Odor Eliminator MERV 8 synthetic media (comparable with Clean Living Odor Defense MPR 600) is recommended to prevent undesirable smells from food, smoke, pets, and other sources. This does not take away from its ability to trap 90% of airborne particles, protecting your home or business from debris, lint, pollen, mold, dander, and other forms of dust without impacting air flow. The high-quality construction features an electrostatically charged, pleated design that captures more harmful particles and prolongs the products lifespan by three times that of fiberglass models. Plus, our industrial-grade beverage board frames are paired with dual wire backings that significantly outperform traditional cardboard compositions by improving structural integrity with their ability to endure temperatures up to 200 degrees Fahrenheit. Installation is also made simple with the addition of easy-to-understand arrows that help identify the direction of air flow and subsequently the way the filter needs to be placed. To top it off, all our components are 100% manufactured within the United States and designed with recyclable materials, providing an eco-friendly alternative to enhancing your air quality. FilterBuy: Breathe Freely!
