Our filters not only purify and alkalize the water but they also re-mineralize it.
Some of the minerals are potassium, selenium, magnesium, calcium, zinc, iron, lithium, and trace amounts of sodium are indeed added to soften water as zeolite has a natural trace sodium content. All minerals added are trace amounts.
We are so sorry to hear that the water has an off taste, but that may be normal when you start to use alkaline water. Even if you drank alkaline water before, ours can still have a different taste as we are also adding in over 20 trace beneficial minerals.
When people first start drinking alkaline water, it can have an "off" taste as their bodies become accustomed to drinking alkaline water and as they detox, which starts in the mouth. You may experience a slightly odd taste in the water and this will slowly disappear over the course of up to two/three weeks.
It is all due to the high alkaline levels in the ionized water.
Your body is becoming acclimated to an alkaline environment and your body is also detoxing during this break-in period.
We recommend that people start out slowly, perhaps drinking a quarter cup to start with and building up over the course of two weeks, or so, acclimating your body to a new alkaline environment.
