The water in the water purifier in the community is mostly pure water. Pure water tastes good. However, purified water not only removes bacteria and harmful substances, but also removes minerals and trace elements beneficial to human body, and has no nutritional effect. Therefore, if people drink pure water for a long time, not only their health will be affected, but also some diseases will occur in severe cases.
After the installation of water purifiers in some communities, there is basically no maintenance, and there is no timely cleaning and filtering of consumables, which is easy to cause pollution and cannot purify water. The water purifier can purify water, because the filter element can partially remove floating impurities such as sediment, rust and moss in water. The filter element absorbs a lot of harmful substances every time it runs. Whether the water quality of the water purifier reaches the standard depends largely on whether the filter element is replaced regularly. If it is not replaced in time, the quality of pure water may be worse than tap water, which will bring hidden dangers to consumers' drinking water safety.
