When your tap water arrives at your home, it will usually be a little over neutral in pH ~ around 7.5.
It will, however, be robbed of its electrical negative charge and will almost always have a 'positive' ORP . This means it has no antioxidant abilities and cannot assist your body in the fight against oxygen free radicals. On the contrary, it actually robs you of energy as you drink it.
The measurement of this positive or negative charge is expressed in millivolts, so an ORP reading on our ORP meter of tap water will most likely show around +350 millivolts. After it has been through Ionizing Water filters it will most likely show anything from -150 to -650mv (depending on the amount of soluble minerals in the water and on the original pH of the water).
Here's where it gets a little tricky. Some device vendors claim antioxidant effect because their water units reduce the positive charge (+350mv). What they don't tell you is that they don't reduce it enough to turn it negative. ONLY when your water shows a negative ORP (less than zero) is it antioxidant capable. Claims to the contrary are like saying "Well, your car is still muddy, but look how well we partially cleaned it!"
It's a similar situation with alkalinity. As we already mentioned, your water is already arriving at your sink with a mild alkalinity. That's because local authorities 'doctor' it with lime to keep it the alkaline side of acid, for two reasons;
- They are bound by law to do so
- Acid (less than pH 7) water is a willing host for microorganisms, bacteria and viruses.
Scientists at Shiga university in Japan have conducted long term research into optimum alkalinity of drinking water for health, and have determined it to be from
pH 8 to 9.5. Our own research has confirmed that no other devices we know of are capable of delivering a precise pH with a range all the way from neutral up to pH 10. If you are considering other devices please keep these two important facts in mind.
- You need a negative charge in your drinking water for it to be at all antioxidant.
- You need the ability to adjust pH for each individual user or family member.
The success of Ionizing water filters worldwide is due primarily to the marriage of technology and age-old water principles in the form of computerized individual pH and ORP capabilities. The precision of this onboard computerized measurement cannot be duplicated in systems without electricity, no matter what they say.
If in doubt, ask for a test of your water ionizer. This will demonstrate to you whether you are getting what you pay for.
Remember, it's not about how good your water filter is or how long it will last. It's about how long YOU want to last and how good YOUR life will be!
