It is easy for a home water filtration system to address the problem of heavy metals in your water but only if done properly. Pure Elements focuses on this very problem with each of their Healthy Home Solution water filters. Iron, lead, mercury, arsenic, zinc and silver are greatly reduced due to the design of this water filter and conditioner. Many of our competitors DO NOT have this component in their filters. Their systems lack the ability to pull out heavy metals. While doing research on whole home water filters, be sure to make sure that the filter you purchase has the capability of reducing heavy metals.
