How the media works

The heart of this system’s effectiveness lies in its KDF-55 combined with catalytic carbon media—a potent duo that doesn’t just filter but actively fights bacteria. KDF-55 uses a specialized process that changes the chemical makeup of waterborne bacteria, suppressing their ability to grow and multiply. Meanwhile, catalytic carbon excels at absorbing chlorine and neutralizing odors, improving both the safety and the taste of your water. Together, they create a bacteriostatic environment inside the tank, reducing bacterial colonies before they can enter your home’s water supply.
