The most common questions about water types, water filters, and more.
Third Wave Water minerals should be added to any kind of "empty water." This includes distilled water, deionized water, reverse osmosis (RO) water, or water from a Zero Water filter. When you add minerals to any of these "empty waters" (water with li
No. All Third Wave Water mineral profiles create permanent hardness, which does not add to limescale formation to your coffee makers. However, it is recommended that you use only our profiles without chlorides in your espresso machine. Some equipment
If you are wary of using distilled water or any other form of empty water because you have heard it is bad for you and your equipment, don't worry!. Once you add Third Wave Water minerals into distilled water, it is no longer distilled water, but a u
TDS stands for "Total Dissolved Solids," and represents the amount of "stuff" that is dissolved in a liquid. This stuff can be organic matter, minerals, and even some chemicals (depending on where your water is coming from). TDS matters because it ef
The water you are using may not be truly "empty" water. For the most accurate results, test your water before and after adding TWW minerals. Starting water should read at 0-9 TDS. The TDS meter is calibrated to read potassium rather than sodium. Pota
Yes. Since empty water (e.g. Distilled Water, Reverse Osmosis Water, Deionized Water, etc) does not have chemicals to reduce bacteria growth (like chlorine and chloramine) it must be handled differently. Over time, you may start to notice some bacter
Empty water can sometimes be found in the United States at the following locations:. If distilled water is unavailable where you live, there are several different options that can be great substitutes!
When dealing with unprotected water, or water that does not have any chemicals like chlorine or chloramine in it, a harmless bacteria called "biofilm" can grow. Some forms of unprotected water include distilled water, reverse osmosis water, and even
TDS, or Total Dissolved Solids, is a measurement of the amount of "stuff" that has dissolved in your water. This is measured in Parts Per Million, or ppm. For each Third Wave Water Profile, this number can vary because different profiles have differe
Both reverse osmosis (RO) and deionized water are suitable for making any of our profiles. They are equally effective as long as no minerals have been added back to them after the filtration process, ensuring a pure and consistent result for your cof
Yes. Our mineral profiles are completely safe for your equipment. Not all calcium is "bad" calcium. CaCO3, Calcium Carbonate, is bad calcium. It is formed from the reaction of calcium cations and carbonate ions that are commonly found in many natural
Yes and no. While tap water is technically safe to consume and brew your coffee with, it ends up causing issues in your equipment and in your coffee's overall extraction and flavor. Tap water, spring water, bottled water, and filtered water, can all
