Our filters serve as your defense against common allergens, while also saving you money. A simple filter change not only prevents costly repairs but also reduces your monthly energy costs. All of our filters are made right here in the USA. We offer premium features such as a pleated, electrostatic design that captures a multitude of particles. Moreover, our robust reinforced beverage board frame ensures durability, even in extreme temperatures.

We opted for the lion because, much like this majestic king of the land, we aim to deliver quality fit for royalty. Our filters are MERV 8 rated and come in a 3-pack with a size of 20" x 24" x 1" (Actual Size: 19.5" x 23.5" x .75"). They are fully manufactured in the United States, using the highest quality materials and construction (EPA Establishment Number: 103501-FL-1).

Our filters can last up to 90 DAYS before needing replacement. We do recommend changing your home air filter every 30 - 90 days for 1 inch filters. This will help maintain the longevity of the intended application like A/C and heaters. The pleated design captures more particles and extends the lifetime of the filter. Merv Filters trap airborne particles without impacting air flow, and you'll feel the difference in just 48 hours.

Installing our filters is fast and easy. Simply open, slide, and close! It's a simple yet effective replacement air filter for your home.
