Why should the filter element of the water purifier be replaced regularly?

Here, we must first understand the working principle of the water purifier. Generally speaking, a complete water purifier is composed of filter elements with different functions. Such as PP cotton, activated carbon (T33, AOC), ceramics, KDF, UF, RO or special materials. The first four kinds of core materials are mainly used for pre-treatment, and the latter is used for end filtration. The service life of the first two core materials is relatively short, generally 2-5 months for PP cotton and 8 months to 1.5 years for activated carbon. Water first enters from the front (PP, activated carbon). This process is to filter large impurities, such as sediment, rust, large floating objects and so on. And partially remove different colors and smells. Pre-filtered water enters the filter element with higher precision, thus removing small impurities, bacteria, heavy metals and other substances harmful to human body. Here, many friends will ask: Where have all the filtered substances gone? They are all attached to the wall of the filter element, and some penetrate deeper. This is when we changed the core, we found that there was stickiness around the filter element, some were light yellow and some were light red. These things are substances that bring danger to people's health. Adsorption saturation of filter element. A good filter element should not only have a large spread (the largest is as big as a basketball court), but also have a large thickness and strong natural adsorption capacity. When the adsorption of the filter element reaches saturation, the filter element must be replaced to ensure the effluent quality. Filter elements are consumables, just like printer cartridges, which need to be replaced when they are used up. Is there a water purifier that does not need to change the filter element after use? Yes, but the price is higher. The life of the filter element is the life of the machine, such as Bainuoken in America. This machine has good sealing performance and high price. Generally speaking, the life of the whole machine is 60 tons of water output. After 60 tons, the whole machine has to be sent to the garbage station. The unused new filter element has also been replaced with the main filter element, and the front end position is backwashed. As mentioned above, the pre-treatment is to filter large impurities, and the pre-treatment backwashing is to wash large impurities and discharge wastewater. This is to protect the rear filter element and prolong its life. However, as many dealers said, the rear filter element does not need to be replaced, which only prolongs the life of the rear filter element. This kind of machine is not cheap. Central water purifier. The structure and accuracy of the central water purifier are different from those of ordinary cabinet, hanging and vertical. This kind of water purifier has high effluent rate and poor accuracy. Because of its different structure, it must be equipped with backwashing function. Generally speaking, there is a little more waste water. Suitable for families with high economic living standards and requirements, it can be seen that its price is not high.
