This ionic shower head contains mineral stones which emit negative ions to purify and filter water, control pH and absorb lime deposits. The shower head is designed to spray very fine jets which soften water pressure and give a spa-like shower experience with relaxing effects. The enclosed stones consist of two types of minerals: red mineral stones for water mineralization, offering benefits for the skin, and grey tourmaline stones that help to control the pH of water. In addition to purifying water and filtering both chlorine and impurities, these balls improve skin and hair softness, purify water, as well as provide a sense of freshness throughout the body. The hand-held shower head saves up to 30% of water. It is made of stainless steel and ABS and includes a standard connection for the shower hose. The shower head is easy to install, so you just have to connect the hose to the hand-held shower head and turn it clockwise. It also features three spray settings: rainfall, jetting and massage. The product measures 22.5cm in length and a head diameter of 7.9cm. It weighs 249g.
