The earliest water ionizers only offered a single-stage carbon filter. Carbon is a great filtration media for removing chlorine and most other impurities from your water. Carbon is also great because the minerals that are needed during water electrolysis pass through it. But, carbon alone does not get the smaller contaminants, chemicals and heavy metals out of your water. To get those out you need multi-stage water filtration systems.
As water ionizers advanced over the years, they added more stages to their filters. The most common stages that they offered were a sediment filter to take the bigger impurities out and activated carbon to kill bacteria. Even to this day you see many water ionizers for sale that offer this simple filtration design. But even these three stages is not enough. Here’s why.
United States tap water is very challenging. It has a lot more in it besides bacteria and chlorine. Most tap water in the United States has a wide range of contaminants, such as leftover pharmaceutical drugs, fluoride, heavy metals, radioactive materials, nitrates and nitrites from farming, pipe cleaners, and more.
To remove all of these different contaminants, you need more stages of filtration. More expensive water ionizers add ceramic filtration to their water filtration system. Ceramic filtration targets some of the smaller contaminants in the water. But even a carbon, ceramic, and sediment filtration system still isn’t enough!
The most advanced multi-stage water filtration systems, like those offered in Water for Life USA water ionizers, have all of the above stages but also add ion exchange resin to remove fluoride and heavy metals from the water. The ceramic filters they offer is are also more advanced, specifically designed to target difficult contaminants. Water for Life USA water ionizer filters not only offer all of these stages of filtration, but they repeat those stages as well through the use of a dual filter multi-stage water filtration system. That means your tap water is passed through most stages twice! The end result is that you get water that is 99.99% pure.
