Filterbuy's 24x30x1 MERV 13 pleated filters come in a 2-pack and are built for furnaces, AC units and heat pumps that take a 1-inch filter. MERV 13 media captures fine particles such as smoke, pollen, mold spores and dander while Filterbuy claims it still keeps airflow up. The frame is beverage board with dual wire backing, rated to 200°F and made in the USA. At $55.98 for two at Best Buy as of November 7, 2026, the price sits at the low end of what this 2-pack has recently cost across the three stores listing it.

With 9,856 ratings averaging 4.7 out of 5, buyers largely report the filters fit as expected and noticeably cut down dust. Complaints center on the gap between nominal and actual dimensions and on airflow in older systems.
The Filterbuy replacement air filter 24x30x1 (actual size: 23.88" x 29.88" 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 13 synthetic media (comparable with Healthy Living Ultimate Allergen Defense MPR 1900 & FPR 10) is recommended if you have a respiratory illness (such as asthma) with its capability to trap 98% of dust particles while protecting your home or business from bacteria, smoke, smog, lint, pollen, mold, dander, and other forms of debris without impacting air flow. High quality construction features an electrostatically charged design with 16 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.
