Filterbuy takes pride in being a one-stop shop for all of your air conditioner, furnace, or HVAC system filter replacements. We offer hundreds of custom sizes in a variety of filtration ratings to ensure you can find the perfect fit, regardless of your specific needs. Our goal is to provide you, your family, and your community access to clean indoor air that enables you to live and breathe freely.

What sets our products apart is the premium features that provide an enhanced filtration experience. Our filters feature a pleated, electrostatic design that captures more particles, and a reinforced beverage board frame capable of withstanding extreme temperatures.

We empower customers to simply purchase the exact filter size they need from the comfort of their homes. Our robust supply chain ensures we can deliver these custom sizes quickly at no extra cost. We love being able to provide a service that helps keep our community healthy.

The Minimum Efficiency Reporting Value (MERV) rates the ability of filters to trap particles on a scale of 1-20, with 20 capturing the smallest microns. MERV 8 air filters offer standard protection (90% of airborne particles), MERV 11 provide superior protection (95%), and MERV 13 offer optimal protection (98%), suitable for larger homes, businesses, and those seeking the best filtration.

We also offer MERV 8 air filters with activated carbon, perfect for inhibiting unpleasant odors while maintaining reliable MERV 8 quality. Customers can choose from various popular sizes, including 16x20x1, 16x25x1, 20x20x1, and 20x25x1.

When it comes to air filters, the nominal size is a rounded number, while the actual size depicts the filter's precise dimensions. If your current filter doesn't have a listed size, measure the width, length, and depth to find the actual size, then round up to the nearest inch for the nominal size.

Replacing air filters is essential for maintaining a healthy lifestyle, as dirty air can lead to respiratory issues. We generally recommend changing the filter every 90 days to keep your system running efficiently and the air clean, though this may vary based on factors like pet ownership and allergy concerns.

Our filters are universally compatible and will work with any furnace, air conditioner, heat pump, or HVAC system, as long as you choose the proper size. The number of filters needed depends on the specific needs of your home or business.

Changing the filter is a simple process – turn off the power, remove the old filter, and insert the new one in the direction of airflow, then replace the cover and turn the power back on.

At Filterbuy, we are passionate about championing indoor air quality and ensuring everyone has access to clean, healthy air. Our green-framed filters, made from high-quality materials in the USA, symbolize the peace of mind that comes with knowing your home or business is being properly cared for. With our subscription service, we make it easy to never forget to change your filters on time.
