At Filterbuy, we take pride in being a one-stop-shop for all your air conditioning, furnace, and HVAC system filter replacement needs. To ensure you find the perfect fit, regardless of your specific requirements, we offer hundreds of custom sizes across a variety of filtration ratings.

Our goal is to provide you, your family, and your community with access to clean indoor air, enabling you to live and breathe freely. What makes our products unique are the premium features that deliver an enhanced filtration experience. These include a pleated, electrostatically charged design that captures more particles, as well as a reinforced beverage board frame capable of withstanding extreme temperatures.

By giving customers the ability to easily purchase the exact filter size they need from the comfort of their homes, and leveraging our robust supply chain to deliver these custom sizes quickly at no extra cost, we aim to solve the problem of finding the right fit. Ultimately, we love being able to provide a service that helps keep our community healthy.

Our 22x22x1 replacement air filters are designed for furnaces, air conditioners, heat pumps, and HVAC systems. With an actual size of 21.50" x 21.50" x 0.75", these MERV 8 synthetic media filters (comparable to MPR 600 & FPR 5) protect homes from dust, pollen, and more by trapping 90% of airborne particles without impacting airflow.

Electrostatically charged and pleated, these filters capture more harmful particles, last 3 times longer than fiberglass models, and are 100% manufactured within the United States. The industrial-grade beverage board (recyclable) frames with dual wire backings improve structural integrity, outperforming standard cardboard designs.

Please note that if you receive items with a different label, frame, or media than what is pictured, any such alteration is purely cosmetic, and your filter will still function exactly as described.

In addition to our 22x22x1 offering, we provide a variety of other popular sizes, including 16x20x1, 16x25x1, and 20x20x1, all available in 4-packs. These filters cater to the needs of healthy families, basic home requirements, allergy sufferers, pet owners, and even large rooms or medical settings, with filtration effectiveness ranging from 90% to 98% for airborne particles.

Whether you're looking for standard, superior, or optimal protection, Filterbuy has you covered with MERV 8, 11, and 13 air filters to suit your specific needs. We're committed to championing indoor air quality and believe that everyone, everywhere deserves to breathe clean, fresh air.
