This helps us achieve our goal of providing you, your family, and your community access to clean indoor air that enables you to live and breathe freely.

What makes our products unique? We offer premium features that provide an enhanced filtration experience. Our pleated, electrostatic design captures more particles, and our reinforced beverage board frame is capable of withstanding extreme temperatures.

We solve the problem of enabling customers to simply purchase the exact filter size they need from the comfort of their homes. Our robust supply chain ensures 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. Breathing dirty air can put you at risk of developing asthma, allergies, and other respiratory ailments. Old filters can also cause system defects, leading to unwanted expenses via energy costs and repairs.

We generally recommend replacing your filter every 90 days to keep your system running efficiently and your air clean. This timeframe may vary based on factors like filter size, pet ownership, allergy concerns, and the number of people in your home.

Most of 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. If you see a specific brand name on a listing, make sure it matches your unit model.

The number of air filters you need depends on the number of vents in your home. Our selection includes package quantities ranging from 1 to 12 filters, so we've got you covered.

Changing your air filter is easy. After finding the right size, turn off the power supply, remove the cover from your intake vent, take out the old filter, and insert the new one in the direction of airflow. Then, replace the cover and turn the power back on.

At Filterbuy, we care about the air you breathe because we consider it the foundation for maintaining a healthy lifestyle. We work around the clock to ensure you, your family, and your community have access to clean indoor air, free of allergens and pollutants.

We now offer a variety of expert services and hundreds of custom air filter sizes that are compatible with a near-infinite number of systems. This enables us to always provide value with a quality product that empowers you to protect your home or business, regardless of your filtration needs.

Our new, green frames are constructed with the same high-quality materials you have grown accustomed to. We made this switch to help symbolize the peace of mind that comes from knowing your home or business is being properly cared for.

From our first air filter produced in 2013, we have proudly built our business in the USA, now manufacturing in multiple states. This robust, homegrown network gives us the unique ability to swiftly fulfill diverse, custom orders directly to the doors of households and businesses across the country at premium rates.
