How do hidden killers in water, such as heavy metals and bacteria, harm the human body?

　　Pollutants in water include visible impurities, silt, rust, etc., as well as bacteria, viruses, heavy metals, etc. that are invisible to the naked eye. 70% of the human body is made up of water. Once we drink contaminated water, the pollutants in the water enter the body and may erode our health. What are the pollutants in water and what harm will they cause to the human body?

　　Excessive water hardness
　　Long-term drinking of hard water is not good for human health and can easily lead to diseases such as gallstones and kidney stones. It can also cause skin itching, allergic dermatitis and other skin diseases.
　　Excessive iron and manganese
　　Too much manganese in drinking water may cause fatigue, dizziness, headache, memory loss, muscle pain, emotional instability, loss of appetite, vomiting, diarrhea, etc. According to research by scientists in the United States and Finland, excessive manganese and iron in the human body have an impact on the heart, and are even more dangerous than cholesterol. Excessive arsenic: Long-term drinking of water with high arsenic content will cause fatigue, weakness, palpitations, convulsions, and skin damage, causing pigmentation, keratosis, molting, hair loss, and skin cancer.

　　Chromium exceeds the standard
　　If the chromium in wastewater exceeds the standard and enters the drinking water source, it may pose a threat to human health, causing bronchial asthma, skin corrosion, ulcers and allergic dermatitis. Long-term exposure to chromium may also lead to respiratory cancer.

　　Fluoride exceeds the standard
　　Chronic poisoning caused by long-term intake of fluorine elements exceeding the human body's needs is a systemic disease that mainly affects hard tissues such as bones and teeth. Early lesions are fluorosis caused by damage to the developing enamel. Continued development can cause bone changes, manifested as back and leg pain and joint movement obstruction.

　　Bacteria and viruses
　　80% of the world's diseases are related to water contamination by parasites, viruses and bacteria. Typhoid, cholera, gastroenteritis, dysentery and infectious hepatitis, etc.

　　So, how to deal with pollutants in water?
　　Water purifiers can effectively remove various pollutants such as bacteria, residual chlorine, heavy metals, rust, mud and sand, and the water tastes good and can be drunk directly without boiling. It is an ideal drinking water solution for families.
　　However, it is worth noting that one of the most core components in the water purifier, the filter element, is called the "heart" of the water purifier. It is a consumable and each filter element has its service life.

　　Common filter element replacement cycle
　　PP cotton filter element
　　Main function: filter large particles of impurities such as mud, rust, etc. in water. Use period: 3-6 months
　　Folding PP filter element
　　Main function: filter large particles such as mud, rust, algae, floating objects, etc.
　　Use period: 12-18 months
　　US composite filter element
　　Main function: quickly adsorb residual chlorine, bacteria, organic matter, etc. to remove foreign colors and odors
　　Use period: 12-18 months
　　Activated carbon filter element
　　Main function: adsorb foreign colors, odors, organic matter, some heavy metals, etc. in water
　　Use period: 6-12
　　Ultrafiltration membrane filter element
　　Main function: filter microorganisms, bacteria, colloids, macromolecular organic matter, etc. in water. Use period: 1-2 years
　　RO membrane filter element
　　Main function: filter pesticides, bacteria, viruses, heavy metal ions, microorganisms and inorganic salts. Use period: 2-3 years

　　The harm of not replacing the filter element in time
　　01 The filter element is saturated and the purification effect is weakened
　　When the filter element is saturated and has not been replaced, the impurities in the water are still accumulating, which will cause the filter element to be blocked, the water output of the water purifier is greatly reduced, and the filtering effect is greatly reduced.
　　02 Overload work wastes money and the life of the water purifier
　　If the filter element is not replaced for a long time, it will not only affect the life of other filter elements in the water purifier, but also make the operation of the entire water purifier sluggish, affect the life of the water purifier, and increase the cost.
　　03 Lead to the growth of bacteria and may cause health problems
　　If the filter element of the water purifier is not replaced in time when it reaches the saturated state, not only the water purification effect will deteriorate, but the water purifier may also become a "sewage purifier". Because of the presence of harmful substances attached to the surface of the water purifier filter element in the saturated state, it is easy to cause bacteria to grow and pollute the water quality.
　　The water purifier can provide you and your family with a safe, healthy and comfortable drinking water environment. At the same time, in order to ensure the cleanliness and hygiene of the water quality, you must remember to replace the filter element in time!
