Founded in 2002 and headquartered in Pennsylvania, USA, the ZeroWater brand is mainly engaged in water filter bottles. ZeroWater is a typical technology-based company that supplies purified water to the pharmaceutical industry, nuclear power plants and naval submarines, and has only been involved in the water filter pot industry for a short time. With years of technology accumulation, ZeroWater's water filter jug has been an instant success and has been the No. 1 seller in the North American market for many years. The ZeroWater water filter jug is extremely performant, ranking at the top of several review sites, with the ZP-010 and ZD-013D ranking second and third in the U.S. Consumer Reports, behind Clear2O's CWS100 and being recommended.
 
ZeroWater's filter cartridge uses a 5-stage filtration unit that uses a particle filter to remove small particles of sediment, a suction sponge to absorb contaminants, activated carbon to remove odors, ion exchange resins to replace metal ions, and a high-density filter membrane to remove ultrafine particles. ZeroWater claims that the TDS value of the filtered water is 0, which meets the standard for direct drinking, hence the name "Zero Water". The test results of the well-known home evaluation website Your Best Digs show that the TDS value of ZeroWater filtered water can indeed be reduced to 0, which is the only product that can reduce the TDS value to 0 at present.
 
ZeroWater essentially filters minerals from the water and is actually producing deionized water, which is why it claims to have a 0 TDS value after filtration. This water has reached the extreme of soft water, and it tastes better when used for cooking, tea and soup, which is also the reason why it is sought after. It should be noted that deionized water is different from purified water, because deionized water may contain harmful substances such as viruses, it is not recommended to drink it directly, but purified water has no hidden danger.
 
However, ZeroWater's water filter cans are mediocre in their ability to remove chloroform, so the filtered water may still have some disinfectant smell. Because ZeroWater water filters need to filter more inorganic salts, the ion exchange process takes longer than other brands. One of the highlights of the Zerowater water filter jug is that it is equipped with a TDS detector on the top of the kettle, and consumers will come with a TDS detector pen when purchasing the water filter jug, which can measure the TDS value of the water before and after filtration.
 
ZeroWater's water filter jugs have a lot of products, but the difference is very small, and they are divided into different series only according to their capacity. ZP-010 is a water filter pot with a total capacity of 2.3 liters, which can filter about 10 cups of water at a time, in addition to the normal spout water, there is also a water outlet button at the bottom of the product, which can press the water out. ZD-013 can filter 8 cups of water at a time, suitable for 1-2 people; The ZD-018 can filter 18 cups of water at a time, which is suitable for a large number of families.
 
Zerowater's product body is made of food-grade synthetic resin, and its filter element is common in all its products, and there is no clear service life, and the amount of water that can be filtered is estimated according to the formula "20,000 ÷ TDS value of pre-filtration water", but the extreme purification level is a great test for the filter element, and the use in areas with poor water quality will greatly shorten the life. In addition, although it is not directly equipped with a filter life indicator, ZeroWater officially recommends replacing the filter element when the detector pen shows "006", which is more intuitive.
 
Although hard water is harmless to the human body, the water quality will bring inconvenience to life, such as scaling the kettle and reducing the efficiency of cleaning products. For South China, where the total hardness value of tap water is about 50, the practical significance of reducing TDS to 0 is not significant. On the contrary, the total hardness value of tap water is generally above 300 in North China and Northwest China, which may be more needed, but the long-term use cost will be relatively high, and household water purifiers are undoubtedly a better choice.
