We love being able to provide a service that helps keep our community healthy. We offer a variety of air filter sizes and filtration ratings to cater to different needs, from standard protection for healthy families to optimal protection for larger homes or businesses.

The Minimum Efficiency Reporting Value (MERV) rates the ability of filters to trap particles on a scale of 1-20, with higher numbers capturing smaller particles. 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. MERV 13 filters are perfect for larger homes or businesses, and those who want the best possible filtration experience. We also offer MERV 8 filters with activated carbon, which are perfect for homes or businesses that want to inhibit unpleasant smells.

Our filters are universally compatible and will work with any furnace, air conditioner, heat pump, or HVAC system, as long as you choose the proper size. We generally recommend replacing your filter every 90 days to keep your system running efficiently and air clean, but this can vary based on factors like the number of vents in your home, the presence of pets, allergy sufferers, and more.

At Filterbuy, we are committed to championing indoor air quality and ensuring that everyone, everywhere, has access to clean indoor air. We are proud to be an American-made company, with a robust manufacturing network that allows us to swiftly fulfill diverse, custom orders across the country. Our new, green frames symbolize the peace of mind that comes from knowing your home or business is being properly cared for.
