At Filter King, our mission is to keep your air fresh and clean, no matter if it's dust, pollen, or smoke that's troubling you. Our filters work wonders in homes, offices, and hospitals alike. What sets us apart is our extensive selection - we offer over 800 air filter sizes, all ready to go.

We specialize in crafting top-quality filters that make a genuine difference. Find the ideal filter for your space, and let's work together to ensure the air you breathe is the best it can be. 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 proudly 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 as our symbol because, much like this majestic king of the land, we aim to deliver quality fit for royalty. Our 4-pack MERV 8 rated air conditioner filters, sized at 20" x 25" x 1" (actual size: 19.5" x 24.5" x 0.75"), are the perfect example of this commitment to excellence.

Fully manufactured in the United States using the highest quality materials and construction, our filters can last up to 90 days before needing replacement. We recommend changing your home air filter every 30 to 90 days for 1-inch filters, as this will help maintain the longevity of your air conditioning and heating systems.

The pleated design of our filters captures more particles, extending the lifetime of the filter and protecting your home. The MERV rating ensures these filters trap airborne particles without impacting air flow, so you can feel the difference in just 48 hours.

Installation is a breeze – simply open, slide, and close. Our replacement air filters for the home are a simple yet effective solution to keep your indoor air quality at its best. Visit our store to find the perfect filter for your needs, and let Filter King help you breathe easier, day in and day out.
