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

Our products are unique because we offer premium features that enhance the filtration experience. Our pleated, electrostatic design captures more particles, and our reinforced beverage board frame can withstand extreme temperatures. We give customers the ability to easily purchase the exact filter size they need from the comfort of their homes, and 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. By replacing air filters regularly, you can maintain a healthy lifestyle, as 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 energy costs and repairs.

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

Our selection includes a range of MERV (Minimum Efficiency Reporting Value) ratings, which indicate a filter's ability to trap particles. MERV 8 filters are perfect for almost any home or business that wants great indoor air quality at a reasonable rate, capturing 90% of airborne particles. MERV 11 filters are ideal for homes or businesses with pets, smokers, or allergy sufferers, capturing 95% of particles. MERV 13 filters offer the best possible filtration, capturing 98% of particles, and are perfect for larger homes or businesses.

We also offer MERV 8 filters with activated carbon, which can help inhibit unpleasant smells while providing reliable MERV 8 quality.

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. The number of filters you need will depend on your specific situation, but our selection includes package quantities ranging from 1 to 12 filters.

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

Our robust, homegrown network of manufacturing facilities across the U.S. allows us to swiftly fulfill diverse, custom orders directly to households and businesses nationwide.
