"Total Dissolved Solids (TDS) are the total amount of mobile charged ions, including minerals, salts or metals dissolved in a given volume of water, expressed in units of mg per unit volume of water (mg/L), also referred to as parts per million (ppm). TDS is directly related to the purity of water and the quality of water purification systems and affects everything that consumes, lives in, or uses water, whether organic or inorganic, whether for better or for worse."
I did a quick little test just to use as a reference to show you guys the comparisons between tap water, bottled water, and Zero Water and their contaminants... It comes with it's own TDS tester which is simple to use, all you do is turn it on, wait for the display to read "000" and plunge it into a cup of water, that's it! I'm not sure if it's just placebo, but when I drink Zero Water it feels lighter almost, like I'm drinking air; it's very fresh and crisp tasting. All you have to do is load tap water into the top portion of the filter and wait! It can take a little while so every few glasses of water or so you gotta be filling it up with more water, not that big of deal though! Try it!
