Safety and hygiene carefully considered.

It keeps the bacterial way through its filter which uses special silver impregnated activated carbon. It properly takes into account both skin safety and hygiene.

Provides plenty of hot water without the impurities for your skin

The two-step filtration system that uses granular coconut shell activated carbon and fibrous activated carbon removes contaminants such as free residual chlorine and trihalomethane.

Two Filter Layers

  • Tap Water

  • Granular Coconut ShellActivated Carbon

  • Special FibrousActivated Carbon

  • Water that is Good for the Skin

Granular Coconut Shell Activated Carbon

Using incredibly high quality granular coconut shell activated carbon as a water absorbent, it physically absorbs odors organic chlorine compounds (such as trihalomethane, tetrachloroethylene), agricultural chemicals (CAT), and mold smells, allowing free residual chlorine to be powerfully removed by the reaction.

Special Fibrous Activated Carbon

Combining ion exchange fiber, it simultaneously assists the granular coconut shell activated carbon filter as it absorbs soluble lead. It enhances filtration power.
