We love being able to provide a service that helps keep our community healthy. Our wide range of filter options caters to different needs, from standard protection (MERV 8) for general home or business use, to superior protection (MERV 11) for homes or businesses with pets, smokers, or allergy sufferers, to optimal protection (MERV 13) for larger spaces or those seeking the best possible filtration.

Understanding MERV ratings is crucial. MERV, or Minimum Efficiency Reporting Value, is a scale that rates a filter's ability to capture particles ranging from 0.3 to 10 microns. The higher the MERV rating, the more efficient the filter is at trapping smaller particles.

Our products come in various sizes, from 16x20x4 to 20x30x4, with options for MERV 8, MERV 11, and MERV 13 filtration. We also offer an Odor Eliminator filter with MERV 8 quality and activated carbon to inhibit unpleasant smells.

Choosing the correct filter size is essential. The nominal size is a rounded number, while the actual size is the precise measurement. If your current filter doesn't have a size listed, measure the width, length, and depth and round up to the nearest inch to find the corresponding nominal size.

Regular filter replacement 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 pet ownership, allergies, and the number of occupants in your home.

At Filterbuy, we're committed to providing better air for all. Our filters are universally compatible and manufactured in the USA, ensuring quality and convenience. With our subscription service, we make the process of changing your filters simple and hassle-free. Join us in our mission to champion indoor air quality and enable everyone to breathe freely.
