Antioxidant filters will NOT do everything that a water ionizer will do because they don’t produce acidic water. An antioxidant filter is more effective in terms of filtration, but it won’t produce acidic water like an electric water ionizer. Both types of technology are very effective when it comes to the health benefits from drinking alkaline water that contains hydrogen ions. Both technologies are effective at removing pesticides from the surface of fruits and vegetables by soaking them in water with high pH levels.
The goal of both systems when it comes to providing health benefits from drinking water is to produce free hydrogen, which acts as an antioxidant. Both systems produce micro clusters which are more readily absorbed. That is where the similarity ends.
Electric Water Ionizers “EWI”:
Electric water ionizers run water across electrically charged plates that produce two streams of water. The “drinking” stream produces a mass of bubbles in your glass when it first comes out of the machine. The bubbles are hydrogen gas. When the beneficial hydrogen bubbles rise to the surface, the benefit of the hydrogen bubbles is lost in the air. That is why I always try to drink fresh water within the first ten seconds of it coming out of the machine.
EWI’s can produce tremendous variation in pH because they are artificially forcing ionization through the power of the use of combining electricity with the available minerals in the water. The pH and ORP of water produced by an EWI will always return to the natural ionization level of the source water, which is dependent upon the level of minerals in the water. Here is a cool way to demonstrate this fact. You can use an EWI to create really low negative ORP such as negative ORP. Run a few ounces of negative ORP water into a glass and use an ORP meter to test the level. Next, put the palm of your hand over the top of the glass to make sure the water doesn’t go flying out, and shake the glass vigorously for ten seconds. When you retest the ORP, you will find that it has dropped hundreds of points. The “temporary” or “unstable” ORP level will disappear as the water reacts to the movement and the air.
EWI’s don’t remove much in the way of contaminants. Some remove more than others (Jupiter’s Biostone filter being the best and Chanson’s tiny carbon block filter being the worst). I believe that every EWI should have a pre-filter system (about $250) because there is a lot of nasty stuff in our water that you can’t see.
Antioxidant Filters “AF”:
Antioxidant Filters produce hydrogen ions naturally by running water over magnesium. This method of ionization was discovered by Dr. Hayashi in the year 2000 when he was working for the Japanese Institute of Water in an attempt to understand why water ionizers were so effective.
The pH and ORP in the water produced by AF’s is “stable”, which is why the ORP level will sustain itself at a much lower level for long periods of time such as a week. I have people reporting from all over the USA and Canada that ORP levels produced by their Alkastream units maintain the ORP level for much longer than the water produced by an EWI. The reason for this is that the AF’s put minerals in the water and the presence of the minerals causes an continued coupling and uncoupling of the hydrogen bonds that join hydrogen atoms to oxygen atoms in a water molecule. It sounds a little “scientific”, but it is true as electrical reactions are taking place in every piece of matter in the universe, including inside our bodies. So, if you plan to take the water with you to work or to the gym, you will get better ORP stability from an AF than from an EWI.
The decision as to whether you should purchase an EWI or an AF should depend upon your needs. If you need acidic water for skin care of sterilizing applications, or for really low ORP levels for strong detoxification, or fighting off cancer (Google Dr. Robert Young’s thoughts on this subject), an EWI is the answer. I always recomment a pre-filter system with a EWI.
If you are looking for clean and ionized drinking water for drinking water, I recommend an AF over an EWI.
