We love being able to provide a service that helps keep our community healthy. Our range of air filters includes MERV 8, 11, and 13 options, catering to different needs – from standard protection for most homes and businesses to superior and optimal filtration for factors like pets, smokers, and allergy sufferers. We also offer MERV 8 air filters with activated carbon for inhibiting unpleasant odors.

Understanding the importance of air filter knowledge, we explain the MERV rating system, which measures a filter's ability to trap particles on a scale of 1-20. We also provide guidance on measuring your air filter, why and when to change it, and how to ensure a proper fit for your system.

At Filterbuy, we are committed to championing indoor air quality. We have proudly built our business in the USA, manufacturing our filters in multiple states, which 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 with our high-quality, American-made products.

Simplifying the filter replacement process, we offer a subscription service that ensures your filters arrive on time as requested, with a convenient discount.
