We love being able to provide a service that helps keep our community healthy. We offer a range of MERV-rated filters, from MERV 8 for standard protection to MERV 13 for optimal protection, as well as odor-eliminating MERV 8 filters with activated carbon. Whether you're a healthy family looking for basic needs or an allergy sufferer or pet owner, we have the right filter for you.

Choosing the correct filter size is important. The nominal size is a rounded measurement, while the actual size is the precise dimension of the filter. If you're unsure of your filter size, use a tape measure to find the width, length, and depth, then round up to the nearest inch to find the corresponding nominal size.

Replacing your air filter regularly is crucial for maintaining a healthy lifestyle and keeping your HVAC system running efficiently. We generally recommend replacing your filter every 90 days, but this may vary based on factors like the number of pets, the presence of allergy sufferers, and the number of people in your home.

At Filterbuy, we're committed to providing clean, healthy air for all. Our filters are manufactured in the USA, and we offer a subscription service to simplify the process of changing your filters. We've been in the filtration business since 1958, and as we continue to expand, we remain true to our values of community investment and personal aid.
