Friendly To Skin General tap water is weak alkaline ranging from pH 7.2 to 7.4, while skin is weak acid from pH 4.5 to 6.5. The difference gives rise to mutual neutralization, leaving alien substances on skins. But water softening makes possible change of the tap water' pH into weak acidity (from 5.2 to 5.6) friendly to the skin. Refreshment After Bathing Such an unpleasant feeling after a bath is attributable to hard water in which calcium, magnesium, and the like are included. These substances are dried and remain in skins just like stone powder. But water softening makes you feel refreshed after a bath because it removes fully something like stone powder by changing hard water into that containing sodium (Na) good for skins. Cleansing Because water softened is weak acid, it washes off the dirt even lodged in pores of the skin, helping you wear makeup and protecting the skin from various skin diseases such as acne, dermatophytosis, eczema, dry dermatitis, and the like.

Only the amount equivalent of one third to half of hard water displays excellent cleansing effects. Sodium (Na) contained in soft water makes hair lustrous and removes static electricity. As well, soft water prevents alopecia by giving life to damaged hair and pores of the skin. Tableware Washing Washing with hard water has extraneous matters or stains left over tableware after full dryness of them, while that with softened water doesn't cause the problem and is very hygienic since it keeps bacteria from propagating.
