What sets Filter King apart is their focus on quality and performance. Their filters serve as a defense against common allergens, while also saving you money.

Moreover, their robust reinforced beverage board frame ensures durability, even in extreme temperatures.

The brand's choice of the lion as their symbol is intentional, as they aim to deliver quality fit for royalty, much like the majestic king of the land. Their filters are MERV 11 rated, ensuring exceptional performance in capturing airborne particles without impacting air flow. These 12-pack air conditioner filters, size 20" x 20" x 1" (actual size 19.5" x 19.5" x .75"), are fully manufactured in the United States and made from the highest quality materials and construction.

Filter King's filters can last up to 90 days before needing replacement, and they recommend changing your home air filter every 30 - 90 days for 1-inch filters. This will help maintain the longevity of the intended application, such as air conditioning and heating systems. The pleated design of their filters captures more particles and extends the lifetime of the filter, and the difference can be felt in just 48 hours.

Changing your air filter has never been easier with Filter King. Their filters feature a simple yet effective design, allowing you to open, slide, and close them with ease. Protect your home and breathe the best air possible with Filter King's premium air filters.
