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 with access to clean indoor air, enabling you to live and breathe freely.

What makes our products unique? We offer premium features that provide an enhanced filtration experience, including a pleated, electrostatic design that captures more particles and a reinforced beverage board frame capable of withstanding extreme temperatures.

We give customers the ability to simply purchase the exact filter size they need from the comfort of their homes. Plus, 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 filters are available in a range of MERV ratings, from MERV 8 for standard protection to MERV 13 for optimal protection. We also offer MERV 8 filters with activated carbon for odor elimination. The MERV rating indicates the filter's ability to trap particles on a scale of 1-20, with higher ratings capturing smaller microns.

Choosing the correct filter size is important. The nominal size is a rounded number, while the actual size is the filter's precise dimensions. If your current filter doesn't have a size listed, measure the width, length, and depth to find the actual size, then round up to the nearest inch for the nominal size.

It's generally recommended to replace your air filter every 90 days to maintain a healthy lifestyle and keep your system running efficiently. Our filters are universally compatible with most furnaces, air conditioners, heat pumps, and HVAC systems.

At Filterbuy, we are committed to championing indoor air quality. We believe everyone deserves access to clean air, free of allergens and pollutants. That's why we offer a variety of expert services and hundreds of custom air filter sizes, all proudly manufactured in the USA. Our new green frames symbolize the peace of mind that comes with knowing your home or business is being properly cared for.

We also offer a subscription service to simplify the process of changing your air filters. Simply find the right product and choose your delivery interval, and we'll make sure your filters arrive on time as requested.

Filterbuy's roots date back to 1958, and we've evolved into the filtration business you know and love today. As we continue to expand, we remain committed to community investment and personal aid at every possible opportunity.
