PP filter element reminds you: how often should the water purifier filter element be replaced?

PP filter element reminds you: how often should the filter element of the water purifier be replaced? One of the water appliances. However, many consumers only find out after purchasing the water purifier that the water purifier is not a durable product once and for all, and it also needs to replace the filter element. In the face of the vague standard of filter life in the filter market, many consumers feel at a loss for the life of the water purifier filter. There are many concepts of water purifiers, but the key is a filter element. The filter element determines the quality and service life of the water purifier. Although the name of the filter element of the water purifier is different, it is the same. The water purification materials are mainly hollow membrane and activated carbon. The hollow membrane is similar to a new generation of food-grade ultrafiltration membrane (an upgraded version of PVC alloy ultrafiltration membrane) produced by Quanlai Water Purifier Co., Ltd. in cooperation with Zhejiang University; while the activated carbon is mainly composed of coconut. Shell, walnut shell, etc. Activated carbon has a strong adsorption effect and is easy to breed bacteria, so some silver ions will be added to it for antibacterial and anti-virus, so it is also called coconut shell silver-loaded activated carbon. However, activated carbon itself is easy to breed bacteria. After the adsorption of organic matter is saturated, not only can it not play the role of adsorption and water purification, but it will release harmful substances, making the water purifier a sewage device. Therefore, ordinary household water purifiers need to be cleaned or even replaced after one or two months of use. The filter element of the water filter is generally marked with the life of the filter element, and some indicate the replacement time according to the time, and some calculate the replacement time of the filter element according to the cumulative flow. However, for the filter elements of more small brand water purifiers on the market, most of them still do not have the filter element marked with the service life. The Lvyuan brand hollow fiber ultra-filter has a service life of three years and is marked. Filter replacement standards are not uniform Lvyuan experts found in the investigation and interview that although the business has listed the life standards of the water purifier filter element: the replacement cycle of activated carbon filter element is half a year, the replacement cycle of PP cotton filter element is 3 to 6 months, and the replacement cycle of quartz sand filter element is 3 to 6 months. The replacement cycle is 1 to 2 years, the replacement cycle of the ceramic filter element is half a year to one year, the replacement cycle of the softening filter element is half a year, the replacement cycle of the hollow fiber ultrafiltration membrane filter element is 3 years, the replacement cycle of the reverse osmosis membrane is 3 years, etc., but these Mostly just a vague conceptual standard. In the interview, many consumers said that the water quality is different in different places, and the frequency of people's use is also different. It is difficult to judge how to calculate the use time of the filter element and how to control the capacity of the filtered water. The filter replacement standard is difficult to determine. Lvyuan experts searched for water purifier filter replacement through Baidu. Statistics show that 1.57 million consumers have had doubts about filter replacement. During the interview, many consumers thought that after purchasing a water purifier, their daily drinking water would be safer, but in the process of using and replacing the filter element, they realized that this safety is only for a short time. Today's water purifier products are mostly equipped with 2 to 6 filter elements. Unlike TV refrigerators, water purifier filter elements cannot be used once and for all. However, it is difficult to measure how the service life of the filter element is a good state for replacement, and water purifier manufacturers are reluctant to pay more attention. A person in charge of the Home Appliance Repair Industry Association said so. Lvyuan water purifier experts also learned from the quality supervision department that the supervision and sampling inspection of water purifiers by the supervision department is mainly concentrated on domestic big brands. Among them, various types of activated carbon filter products found that the unqualified rate of products was relatively high, and the reasons included the unqualified soaking test of total dissolved solids, aluminum and arsenic indexes. In this regard, some water purification equipment experts also pointed out that the service life of the water purifier filter element is only for the water in a certain place as a standard, and this standard is definitely not suitable for all parts of the country. If the water quality in the south is used as the standard, it will be lacking in the north; if the water quality in the north is used as a reference, the water quality in the south will be a little too high, which itself has a lack of standards.
