Our goal is to provide you, your family, and your community with access to clean indoor air that enables you to live and breathe freely.

What makes our products unique? We offer premium features that provide an enhanced filtration experience. Our pleated, electrostatic design captures more particles, and our reinforced beverage board frame can withstand extreme temperatures.

We solve the problem of allowing 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. Our air filters come in various sizes and MERV ratings to cater to different needs, such as standard protection (MERV 8), superior protection (MERV 11), and optimal protection (MERV 13). We also offer odor eliminator filters with activated carbon.

The MERV rating measures the ability of filters to trap particles on a scale of 1-20, with the highest number capturing the smallest microns. MERV 8 filters are perfect for almost any home or business that wants great indoor air quality at a reasonable rate, while MERV 11 filters are suitable for homes or businesses with factors like pets, smokers, and allergy sufferers. MERV 13 filters are ideal for larger homes or businesses and those who want the best possible filtration experience.

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. We recommend replacing your filter every 90 days to keep your system running efficiently and maintain clean air.

At Filterbuy, we are committed to championing indoor air quality and ensuring everyone has access to clean air. Our products are 100% American-made, and we offer a subscription service to make filter changes a hassle-free process. As our company has grown, we've stayed true to our values of community investment and personal aid.
