| Update: I spent a week in Somersworth, NH, and the tap water quality is horrible, in terms of a TDS reading of 150ppm, compared with nyc 40ppm. A single tea bag filter (working with the pump) was only good for purifying 6 liters of water to 1ppm. After that, the next 6 liters went no lower than 82ppm. I continued filtration with an unused filter. | Update: I spent a week in Somersworth, NH, and the tap water quality is horrible, in terms of a TDS reading of 150ppm, compared with nyc 40ppm.

| + | Update: If you want to remove flouride, a TDS meter will not be that helpful, because flouride is added to water at 1ppm. The TDS meter does not have enough resolution to estimate the percentage of flouride that is removed by your filter. | ||

| " The problem with the Zero unit, you see, is that pure water seeks to become contaminated. It will hungrily absorb CO2 from the atmosphere, forming carbonic acid, as well as any contaminants in the air. More dangerous is the fact that the Zero Water Filter removes 100% of the chlorine form the water. If your municipality did that, your community would suffer another yellow fever, legionella or other bacterial/viral disease outbreak. | " The problem with the Zero unit, you see, is that pure water seeks to become contaminated.

| The purification technology in this unit itself is sound, but the product has no technology to keep the water pure once it is made so. In water treatment science it is more expensive to keep water pure than it is to make it pure. I am willing to bet that if you do not sterilize your pitcher daily, you have bacteria growing in the system.

| Pure water will strongly attract any impurity, including contaminants in the air. In order to keep purified water pure, after being transferred out of the filter, you should continue to keep it in a glass container with a sealed lid. Another option is to dirty the water so it is no longer pure! Add some lemon juice, tea, cinnamon sticks or cloves. | Pure water will strongly attract any impurity, including contaminants in the air.

| + | Should drinking water be at a certain pH? Well, I'm taking the pH out and making it completely neutral with the ion exchange resins. There is some marketing fad to sell alkaline water. If it's supposed to be basic, then I've got that covered because I brush my teeth with baking soda. The food you eat will have so much more ions in it than the trace amounts in water. Does it matter that it goes in with the wrong pH, if it quickly gets mixed up with the food in your belly? | ||
