Some of the same minerals from our Perfect Mineral drops are in our new VOC filter, but our Perfect Minerals are little different. Our Perfect Minerals come from the Great Salt Lake in Utah. Its nutrient-rich waters contain over 72 ionic minerals and trace elements that are 8-10 times more concentrated than regular seawater-in precisely the same proportion as healthy human fluids. Our pH + Mineral Boost VOC filter adds calcium, magnesium and a blend of other proprietary healthy minerals to your water.
