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 in that they offer premium features, such as a pleated, electrostatic design that captures more particles and a reinforced beverage board frame capable of withstanding extreme temperatures. This enhanced filtration experience sets us apart.

We solve the problem of allowing customers 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. Our air filters come in a variety of sizes, including 20x20x1, 16x25x1, 20x25x1, and 20x25x5 Honeywell filters.

The Minimum Efficiency Reporting Value (MERV) rates the ability of filters to trap particles on a scale of 1-20, with 20 capturing the smallest microns. Our MERV 8 filters provide standard protection (90% of airborne particles), MERV 11 filters offer superior protection (95% of airborne particles), and MERV 13 filters offer optimal protection (98% of airborne particles). We also offer MERV 8 filters with activated carbon for odor elimination.

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 recommend replacing your filter every 90 days to keep your system running efficiently and the air clean.
