RO reverse osmosis membrane filter, ultrafiltration membrane filter, ceramic filter, PP cotton filter, activated carbon filter, etc. At present, the two most common filter elements on the market are ultrafiltration membrane filter element and reverse osmosis filter element, and activated carbon filter element is generally used as supporting purification products. How to choose the filter element of water purifier?

Which filter element is the best in terms of life, filtration accuracy and material?

From the perspective of filtration accuracy, RO reverse osmosis membrane filter element has the highest filtration accuracy and the most thorough water purification, and the produced water is the so-called pure water.

But this kind of water also has a problem, that is, it is too clean, basically contains no minerals and trace elements, and long-term drinking is not conducive to human health.

Followed by ultrafiltration membrane filtration, the advantage is that minerals and trace elements in water can be retained, but the disadvantage is that heavy metals cannot be removed.

From the life of filter element, ultrafiltration filter element is the longest, which can generally be used for two to three years; Followed by RO reverse osmosis filter, about two years; PP cotton filter has the shortest life and needs to be replaced in 3 to 6 months. The service life of the filter element is not only related to whether it is cost-effective in use, but also related to whether it is convenient in maintenance. Generally speaking, RO reverse osmosis filter and ultrafiltration membrane filter are actually very good, and both have their own advantages and disadvantages. Personally, I suggest that the ultrafiltration membrane filter element can refer to Li Sheng water purifier, which is a representative brand in ultrafiltration. Because it is a new type of PVC alloy ultrafiltration membrane developed by ourselves, the service life is longer, and the ultrafiltration filter element is guaranteed for three years free of charge; If you are worried about the problem of heavy metals, you can choose their kitchen compound water purifier, which can not only remove heavy metals, but also remove residual chlorine, odor and abnormal color, which is convenient.
