At Filterbuy, we take pride in being a one-stop shop for all your air conditioner, furnace, or HVAC system filter replacements. We offer hundreds of custom sizes in a variety of filtration ratings to ensure that you can find the perfect fit, regardless of your specific needs. This helps us achieve our goal of providing you, your family, and your community access to clean indoor air, enabling you to live and breathe freely.

Our products are unique in that they offer premium features that provide an enhanced filtration experience. This includes a pleated, electrostatic design that captures more particles and a reinforced beverage board frame capable of withstanding extreme temperatures.

We solve the problem of allowing customers to simply purchase the exact filter size they need from the comfort of their homes. Additionally, our robust supply chain ensures that 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. Our air filters come in various sizes, including 20x20x1, 16x25x1, 20x25x1, and 20x25x5 Honeywell filters.

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. Our offerings include MERV 8 (90% standard protection), MERV 11 (95% superior protection), and MERV 13 (98% optimal protection) air filters. We also offer MERV 8 air filters with activated carbon for odor elimination.

Customers can choose the filter size and MERV rating that best suits their needs, whether they are looking for healthy families and basic needs, allergy sufferers and pet owners, or those in large rooms and medical settings.

We believe that clean air is the foundation for maintaining a healthy lifestyle, and we are committed to ensuring that everyone, everywhere, has access to it. This is why we work around the clock to provide high-quality, custom-sized air filters that are compatible with a wide range of HVAC systems.

Our new, green frames are not only constructed with the same high-quality materials, but they also symbolize the peace of mind that comes from knowing your home or business is being properly cared for. We are proud to be a 100% American-made company, with a robust, homegrown network that enables us to swiftly fulfill diverse, custom orders directly to the doors of households and businesses across the country.

To further simplify the process, we offer a subscription service that allows customers to receive their air filters on a regular basis, ensuring that they never miss a crucial filter change. This not only helps maintain a healthy lifestyle, but it can also lead to energy savings and reduced repair costs.

As our company continues to grow, we remain committed to our values of community investment and personal aid, staying true to our roots as a small, family-owned and operated business that has been serving customers for nearly 70 years.
