These mineral stones are the perfect way to purify and naturally add minerals to your drinking water. These stones are comprised of maifan stone, a natural stone which has for centuries been used to treat various diseases. It is capable of absorbing soluble heavy metals and impurities in water while also gently releasing rich minerals and increasing the alkalinity of water.

Maifan stone contains an abundance of minerals that are essential to the human body, such as calcium, iron, zinc, magnesium, copper and selenium. Maifan stone also has the ability to effectively remove mercury, lead, cadmium, arsenic and other heavy metals, fluoride and chlorine.

Each bag contains a handful of small maifan stones weighing a total of approximately 1.76 oz (or 50 g). Each stone is approximately 2mm to 6mm in size.

Maifan stones should be replaced approximately every one to three years depending on the frequency of their use.

We recommend against using maifan stones directly in your copper water pitcher, as they may pose a choking hazard and also react with the copper.
