From the brand, the mission of Filter King is to keep your air fresh and clean, whether it's dust, pollen, or smoke. The company offers over 800 air filter sizes, ready to go, and specializes in crafting top-quality filters that make a difference.

What sets Filter King apart is their focus on delivering quality fit for royalty, much like the majestic king of the land, the lion. Their filters serve as a 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 Filter King's filters are made right here in the USA, using the highest quality materials and construction. They feature a pleated, electrostatic design that captures a multitude of particles, and a robust reinforced beverage board frame that ensures durability, even in extreme temperatures.

The MERV 11 rated 4 pack Air Conditioner Filter, with a size of 16" x 20" x 1" (actual size: 15.5" x 19.5" x .75"), is a testament to Filter King's commitment to quality. This filter can last up to 90 days before needing replacement, and it's recommended to change your home air filter every 30 - 90 days for 1 inch filters to help maintain the longevity of the intended application, such as A/C and heaters.

The pleated design of the Filter King filters captures more particles and extends the lifetime of the filter. Merv Filters trap airborne particles without impacting air flow, and the difference can be felt in just 48 hours. The installation process is fast and easy, with a simple "Open, Slide and Close" process.

In conclusion, Filter King is the brand to trust when it comes to keeping your air fresh and clean. With their focus on quality, durability, and performance, you can be sure that your home or workplace will breathe easier with their filters.
