The ‘Tingle-Factor’ is a whole new level of clean freshness you’ll enjoy with the Quatro shower head. The result of extensive development, it works in four innovative ways. First, the water passes through a filter of red tourmaline ceramic ‘stones’. Their anti-bacterial properties remove traces of heavy metals and impurities and soften the water. Stage two is a grey ceramic filter which further removes unwanted trace elements and releases negative ions in the water. Next, natural quartz and citrine crystals reduce chlorine and activate electrons in the water. Finally a stainless steel ‘power plate’ with 292 laser-cut nozzles delivers the ultimate shower, using less water. The result: your skin and hair feel softer and cleaner. It’s like showering in a mountain waterfall, you feel energised, invigorated and tingling all over. And that’s the ‘Tingle-Factor’. Universal fit , attaches to all regular shower hoses, size: L25xDia.8cm.
