Water ionizers, can make your water healthier and some even come with touch screen controls Water ionizers adjust the PH level of the water coming out of your taps and can make it more or less acidic and alkaline depending on how you need it to be. Ionized water is thought to be better for drinking whilst exercising as it has smaller molecules which are easier for the body to absorb. Alkaline water is supposedly high in antioxidants, which work to absorb the errant particles in your body that can increase the risk of cancer. However, it is the touchscreen interface which looks a little like an iPhone strapped to the tap that has fascinated most customers. The handy touchscreen gives easy access to the ionizers settings. It also has the option of audible descriptions and a colour-coded guide to indicate the current PH level of the water. The touchscreen even has an LED temperature indicator to prevent accidental burns.
