Although water purifier and water purifier belong to the same water treatment equipment, there are always many people who will confuse them and think that they are similar. In fact, there are still some differences between water purifiers and pure water machines. Let's first understand the difference between water purifier and water purifier from the concept, characteristics and their respective advantages and disadvantages.
Second, the concept is different.
1 water purifier: chlorine gas in urban tap water, bacteria, viruses, colloids, rust, impurities and other harmful organic pollution caused by secondary pollution are removed by physical means such as filtration and adsorption.
Water purifier: All organic pollutants and inorganic ions in water are intercepted by RO membrane reverse osmosis with ultra-fine precision, and there is a certain amount of wastewater. The effluent is pure water, which can be directly drunk.
Third, the characteristics are different.
1 water purifier: activated carbon, meltblown filter element, microporous ceramics, hollow fiber, KDF, etc. Most of them are used to purify water, and the filter element needs to be replaced and maintained regularly, so it is impossible to remove calcium and magnesium ions from water, that is, it is impossible to solve the problem of water and alkali.
Water purifier: it has the advantages of removing harmful organic pollution such as bacteria, viruses, colloids, rust and impurities, and it also has the advantage of removing scale with a water softener.
Four. Comparison of advantages and disadvantages
1 water filter
A advantages: removing harmful substances in water, retaining minerals and trace elements beneficial to human body, drinking raw, without power supply and waste water.
B. Disadvantages: water and alkali cannot be removed. If you want to remove it, you need to increase the configuration and replace the filter element.
2 pure water machine
A. Advantages: the removal rate of impurities in water is as high as 96% or more, with good taste and pure and sweet water quality.
B. Disadvantages: there is wastewater discharge, and the water output is small, which is not suitable for domestic water. The filter element needs to be replaced regularly. For every liter of water used, 3 liters or more water needs to be discharged. The water purifier purifies the water thoroughly, so the human body needs less minerals and trace elements.
Only unpolluted, mineral-rich and alkaline mineral water is beneficial to health.
