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 that enables you to live and breathe freely.

Our products are unique because we 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. 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 come in various sizes and MERV ratings to cater to different needs, from standard protection for healthy families to optimal protection for larger homes or businesses.

MERV, or Minimum Efficiency Reporting Value, is a scale that rates the ability of filters to trap particles from 1 to 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 factors like pets, smokers, and allergy sufferers. For the best possible filtration experience, MERV 13 filters are perfect for larger homes or businesses.

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

Choosing the correct filter size is essential. The nominal size is a rounded number, while the actual size is the precise measurement of the filter. If your current filter does not have a dimension listed, use a tape measure to record the width, length, and depth, and then round up to the nearest inch to find a corresponding nominal 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, but this may vary based on factors like the number of vents in your home, pet ownership, and allergy concerns.

At Filterbuy, we are committed to providing better air for all. We believe everyone deserves to breathe clean, pure air, which is why we work tirelessly to ensure that you, your family, and your community have access to the best possible indoor air quality. Our filters are 100% American-made, and we offer a subscription service to simplify the process of changing your filters regularly.
