About this item
Product details
The Filterbuy replacement air filter 18x24x1 (actual size: 17.38" x 23.38" x 0.75") ensures that your furnace, air conditioner, heat pump, or HVAC system is circulating the cleanest air possible to help preserve your budget and healthy lifestyle. MERV 11 synthetic media (comparable with Micro Allergen Defense MPR 1200 & FPR 7) is recommended if you have pets or allergies with its capability to trap 95% of dust particles while protecting your home or business from smoke, smog, lint, pollen, mold, dander, and other forms of debris without impacting air flow. High quality construction features an electrostatically charged design with 14 pleats per foot that captures more harmful particles and prolongs the products lifespan by three times that of fiberglass models (replace every 90 days for best results). 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 and withstand exposure to moisture. 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.

Perfect Fit
We have a forced hot air furnace in our home and I always know where to get my filters. Filterbuy site is easy to navigate and to make a purchase. I have ordered from other sites in the past and the size was always to spec. Filterbuy filters take into consideration the fact that it needs to fit into the return and are always a perfect fit.
