Filtered water has passed through a fine strainer and/or activated carbon. While carbon filters reduce bad taste and odours like chlorine, most are not effective in removing contaminants like nitrates, lead, sodium, bacteria..and the list goes on. Cargon filters can also remove organic chemicals, however, most are too small to be very effective.
Consumers today are seeing a wide variety of bottled water on the market. It can be confusing when you look at all the different brands and types of water. How do you know what your're getting?
Spring, Mineral, Natural
All of these bottled waters come from an underground source such as a well or spring. However, these waters may still contain many of the minerals, salts, inorganic metals, and chemicals that can be found in tap water.
Distilled, Purified by Reverse Osmosis
These waters typically come from a well, spring or tap and are processed to remove most contaminants. They must contain 10 ppm of Total Dissolved Solids, (TDS) or less .. compared to Spring Water that typically contains 300 to 450 ppm of TDS.
