Why Do Most People Use Household Carbon Block Filters？

We know that there are many chemicals, particles, bacteria, organic matter and toxins in tap water before it is pre-filtered by the water supply company. Due to the different water quality control standards implemented by different countries and regions, or the use of water filtration equipment and water quality monitoring equipment are not the same,these directly lead to the difference in the quality of tap water in the residents of various regions. 

For running-water companies in many countries, how to effectively treat and filter out the chemical organic matter and toxins hidden in tap water is a challenge they face. Tap water comes from natural springs, reservoirs or other sources of water (such as farmland, lawns, street and industrial runoff).

For health and safety reasons, the water company will filter and disinfect the water first when it is used, whether it is directly used as drinking water.They usually use chemicals such as chlorine to disinfect water. Other chemicals may also be incorporated into the water during the disinfection process, such as volatile organic chemicals, bromates, fluorides, sulfates, nitric acid, and even radioisotopes such as radium. These may be by-products produced after the water has been sterilized. In any case, one or more of them may exist in most tap water and need to be filtered out.

In addition, water needs to pass through a series of long pipeline networks as it travels to individual homes. During this process, bacteria or other impurities attached to the water pipes would have a good chance of contaminating the water again.
