What can the household water purifier filter?
The top 5 best water purifier can filter rust
The water is transported by a galvanized iron pipe, and water and iron are oxidized to form red iron oxide, which further oxidizes to form black ferric oxide. Pipes in new buildings are more susceptible to oxidation. The faucet is turned on for the first time every morning, and the red material in the effluent is rust.
Iron is an essential element of the human body, but as one of the indicators of drinking water, the iron content per liter of water must not exceed 0.3 mg. If the naked eye can distinguish the color of the rust in the water or can smell the rust, the iron content in the water is greatly exceeded.
Excessive iron content, not only the perception, poor taste, long-term drinking, will increase the burden on the kidneys, leading to disorders of the endocrine system, high blood pressure, and other diseases.
2 aluminum and other heavy metals
During the transportation process, heavy metals such as lead are dissolved in the water. Long-term drinking will increase the burden on the liver and kidneys of the human body, and easily cause diseases in the liver, kidney, heart, and nervous system.

Chlorine is a strong oxidizing agent with a pungent odor and a mouthfeel. Chlorine is a tap water disinfectant widely used internationally.
1. “When chlorine interacts with organic matter, such as sweat, it is easy to cause the formation of nitrogen trichloride in the surrounding air, which is very likely to damage the eyes and throat.”
2. “Residual chlorine may cause heart disease, coronary atherosclerosis, anemia, hypertension, liver and kidney discomfort, asthma and emphysema. For many years, the risk of cancer will increase!”
Whether it is surface water or groundwater as a source of water, bacteria and E. coli in tap water can be said to be ubiquitous. The harm of bacteria and viruses, I believe this is no longer necessary.
The World Health Organization (WHO) survey shows that:
80% of the world’s diseases are caused by water pollution; about 1.2 billion people worldwide suffer from drinking contaminated water; 50% of global cancers are related to drinking unclean water; 50% of global deaths are drinking and contaminated Water causes; 25 million children under the age of five die from diseases caused by drinking contaminated water; more than 5 million people worldwide have cholera, diarrhea, and malaria caused by water pollution.
