Metal Free Water is water that is distilled three times to remove impurities and contaminants including metal ions. They are checked with the Heavy Metals Test General Kit to ensure that there are absolutely no metals present.
The Metal Free Water Test Kit was produced especially for users of the heavy metal test kits where users have to find metal free water to produce the specimen solution for testing with the kits. It was found that many of the bottled water or distilled water sold online contained metal ions despite claims to the contrary.
Metal Free Water may also be used for washing because it is clean and may be used for drinking but only for the short term. It is not suitable for long term consumption because there is no mineral content or nutritional value in the water.
