Our goal is to provide you, your family, and your community with access to clean indoor air, enabling you to live and breathe freely.

Our products are unique in their premium features, offering an enhanced filtration experience. They feature a pleated, electrostatic design that captures more particles, and a reinforced beverage board frame capable of withstanding extreme temperatures.

We aim to solve the problem of customers having the ability to simply purchase the exact filter size they need 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. We offer a wide range of air filter options, including 20x20x1, 16x25x1, 20x25x1, and 20x25x5 Honeywell air filters.

The Minimum Efficiency Reporting Value (MERV) rating system measures the ability of filters to trap particles on a scale of 1-20, with 20 capturing the smallest microns. Our MERV 8 air filters are perfect for almost any home or business that wants great indoor air quality at a reasonable rate. MERV 11 air filters are ideal for homes or businesses accounting for factors like pets, smokers, and allergy sufferers, while MERV 13 air filters offer the best possible filtration experience for larger homes or businesses.

We also offer MERV 8 air filters with activated carbon, perfect for homes or businesses that want to inhibit unpleasant smells with reliable MERV 8 quality.

Choosing the right air filter size is important. The nominal size is a rounded number, while the actual size is the precise measurement. If your current filter does not have a size listed, use a tape measure to find the actual size, then round up to the nearest inch to find the corresponding nominal size.

Changing your air filter regularly is crucial for maintaining a healthy lifestyle, as breathing dirty air can lead to respiratory issues. We generally recommend replacing your filter every 90 days, but the frequency may vary based on factors like pet ownership, allergy concerns, and the number of occupants in your home.

Our air 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. The number of filters you need will depend on the specific needs of your home or business.

At Filterbuy, we are committed to providing better air for all. We champion indoor air quality and believe that everyone deserves to breathe clean, fresh air. Our filters are constructed with high-quality materials, and we are proud to manufacture them in the USA. We also offer a subscription service to make the filter replacement process easier and more convenient.

Our company has evolved from its inception in 1958 to the thriving filtration business it is today, with a focus on community investment and personal aid. When you see the Filterbuy green frame, you can be confident that you are breathing crisp, pure air.
