This allows us to provide you, your family, and your community access to clean indoor air, enabling you to live and breathe freely.

Our products are uniquely designed with premium features that enhance the filtration experience. We use a pleated, electrostatic design that captures more particles, and a reinforced beverage board frame capable of withstanding extreme temperatures.

We solve the problem of making it easy for customers to purchase the exact filter size they need, right 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. By offering a range of MERV-rated filters, we cater to the needs of different customers, from standard protection for healthy families to superior and optimal protection for allergy sufferers, pet owners, and larger homes or businesses.

Our MERV 8 filters are perfect for almost any home or business that wants great indoor air quality at a reasonable rate. MERV 11 filters are ideal for homes or businesses accounting for factors like pets, smokers, and allergy sufferers, while MERV 13 filters provide the best possible filtration experience, perfect for larger homes or businesses.

For customers who want to inhibit unpleasant smells, we offer MERV 8 filters with activated carbon, providing reliable odor elimination.

We understand the importance of finding the right filter size for your system. The nominal size is a shorthand number rounded to the nearest whole or half inch, while the actual size depicts the filter's precise dimensions. If you're unsure, use a tape measure to record the width, length, and depth of your current filter, 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 and ensuring your HVAC system runs efficiently. We generally recommend replacing your filter every 90 days, but this may vary based on factors like the number of pets, allergy sufferers, or children in your home.

At Filterbuy, we are committed to providing better air for all. We believe that everyone deserves to breathe clean, pure air, and we work tirelessly to ensure that you, your family, and your community have access to it. Our filters are proudly manufactured in the USA, and we offer a subscription service to simplify the process of changing your filters on time.
