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 makes our products unique? We offer premium features that provide an enhanced filtration experience via 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, and our robust supply chain ensures that we can deliver these custom sizes quickly at no extra cost.

Why do we love what we do? We love being able to provide a service that helps keep our community healthy. We are firm believers that everyone, everywhere deserves to breathe clean air, and we work around the clock to ensure that you, your family, and your community have access to it.

Our filters are available in various MERV (Minimum Efficiency Reporting Value) ratings, which measure the ability of filters to trap particles on a scale of 1-20. 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 ideal for homes or businesses accounting for factors like pets, smokers, and allergy sufferers. For larger homes or businesses, and those who want the best possible filtration experience, MERV 13 filters are the perfect choice.

We also offer MERV 8 air filters with activated carbon, which are perfect for homes or businesses that want to inhibit unpleasant smells with reliable MERV 8 quality.

Choosing the correct filter size is important, as the nominal size is a shorthand number rounded to the nearest whole or half inch, while the actual size is the filter's precise dimensions. If your current air filter does not have a dimension listed on the frame, use a tape measure to record the width, length, and depth to find the actual size.

Replacing your air filter regularly is crucial for maintaining a healthy lifestyle, as breathing dirty air can put you at risk of developing asthma, allergies, and other respiratory ailments. We generally recommend replacing your filter every 90 days to keep your system running efficiently and air clean.

At Filterbuy, we are committed to providing high-quality, American-made air filters that are compatible with a near-infinite number of systems. Our new, green frames symbolize the peace of mind that comes from knowing your home or business is being properly cared for. With our subscription service, we make it easy to ensure your filters are replaced on time, and you even get a discount on every delivery when you enroll.
