Filterbuy 20x30x1 MERV 8 Air Filters (4-Pack)

At Filterbuy, we are proud to be 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 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 that enables you to live and breathe freely.

Our products offer premium features that provide an enhanced filtration experience. We use a pleated, electrostatic design that captures more particles, and a reinforced beverage board frame capable of withstanding extreme temperatures. This allows us to solve the problem of giving customers the ability to simply purchase the exact filter size they need from the comfort of their homes, with our robust supply chain ensuring quick delivery at no extra cost.

We love being able to provide a service that helps keep our community healthy. Our filters come in a range of MERV ratings, from MERV 8 for standard protection, to MERV 11 for superior protection, and MERV 13 for optimal protection. We also offer MERV 8 filters with activated carbon for odor elimination.

The MERV rating, or Minimum Efficiency Reporting Value, measures a filter's ability to capture particles on a scale of 1-20, with 20 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 ideal for homes or businesses with pets, smokers, or allergy sufferers. MERV 13 filters are the best choice for larger homes or businesses, and those who want the highest possible filtration.

Choosing the correct filter size is important. The nominal size is a rounded number, while the actual size is the exact measurement. If your current filter doesn't have a dimension listed, use a tape measure to find the actual size, and then round up to the nearest inch to find the nominal size.

It's important to replace your air filter regularly, typically every 90 days, to maintain a healthy lifestyle and keep your HVAC system running efficiently. Most of our filters are universally compatible, but if you see a specific brand name, make sure it matches your unit model.

At Filterbuy, we are committed to providing better air for all. We believe that everyone deserves to breathe clean, fresh air, which is why we work tirelessly to ensure that you and your community have access to the best indoor air quality solutions. Our new, green frames symbolize the peace of mind that comes from knowing your home or business is being properly cared for, and our robust, homegrown manufacturing network allows us to swiftly fulfill diverse, custom orders across the country.

We also offer a subscription service to make the process of changing your filters even easier, with discounts for enrolled customers. As a small, family-owned and operated company with nearly 70 years of experience, we are dedicated to giving back to our communities and staying true to our values as we continue to expand.
