Crystal ECO annual replacement set (K3-K7B-K7)

The set of replacement filters for the Crystal ECO under-counter stationary absorption filter.

The K3 CarbFiber module is primary purification filter that reduces common impurities such as chlorine, lead, bacteria, and solid particles down to 10 microns.
The K7B microfiltration filter featuring a carbon block and hollow fiber membrane that removes impurities as small as 0.1 microns, including bacteria and cysts. Half of its volume is occupied by a membrane with pores 1000 times thinner than a human hair.
The K7 is the final stage filter that removes common impurities down to 0.8 microns, ensuring thorough purification.

This replacement set is efficient for removing harmful impurities from the water such as chlorine, iron, lead, other heavy metals, petroleum products, pesticides, and other organic compounds.
The cartridges do not remove water hardness (excess mineral salts that cause scale) and are designed for soft water.
The complete set is replaced together without the need for special tools, but it's important to replace the cartridges in the correct order to maintain effective filter life.
