How long does the lifespan of the water purifier filter element last? Replace it
Published by Publisher: Baichuan Hengye FilterDate: 2/21/2013 10:56:22 AM Read: With frequent incidents of water accidents and hidden dangers in bottled water appearing in newspapers and on the internet, the water purifier market is becoming increasingly popular, and water purifiers have gradually become one of the essential water appliances in people's lives. However, many consumers only realize after purchasing a water purifier that it is not a permanent durable product and requires replacement of the filter element. Faced with the vague standard of filter cartridge life in the filter cartridge market, many consumers feel at a loss about the service life of water purifier filters.
The service life of the water purifier filter element is unclear
During the investigation, it was noticed that in the entire water purifier market, well-known brands of water purifier filters in home appliance stores generally indicate the lifespan of the filter element. Some indicate the replacement time based on time, while others calculate the filter element replacement time based on cumulative flow rate. However, for the filter cartridges of more small brand water purifiers on the market, most of them still do not indicate the service life of the filter cartridges. The hollow fiber super filter element of Jinglai water purifier brand has a service life of three years and has been labeled.
Inconsistent replacement standards for filter cartridges
During the investigation and interview, the reporter found that although the merchants listed the service life standards for water purifier filters: the replacement cycle for activated carbon filters is one year, the replacement cycle for PP cotton filters is 3 to 6 months, the replacement cycle for quartz sand filters is 1 to 2 years, the replacement cycle for ceramic filters is half a year to one year, the replacement cycle for softened filters is half a year, the replacement cycle for hollow fiber ultrafiltration membrane filters is 3 years, the replacement cycle for reverse osmosis membranes is 3 years, and so on, most of these are just vague conceptual standards.
Many consumers in the interview expressed that the water quality varies from place to place, and people's frequency of use is also different. It is difficult to judge how to calculate the usage time of the filter element and how to control the capacity of the filtered water.
The standard for core replacement is difficult to determine
The reporter searched for "replacement of water purifier filter element" on Baidu, and the statistics showed that 1.57 million consumers had doubts about filter element replacement. During the interview, many consumers thought that after purchasing a water purifier, their daily drinking water would be safer. However, during the process of replacing the filter element, they realized that this safety was only temporary.
Nowadays, most water purifier products are equipped with 2 to 6 different filter elements. Unlike televisions and refrigerators, water purifier filter elements cannot be used permanently. However, it is difficult to measure the optimal replacement life of the filter element, and water purifier manufacturers are also unwilling to pay more attention, "said a person in charge of the Home Appliance Maintenance Industry Association.
In fact, in June of this year, the Ministry of Health conducted spot checks on some imported small water purifiers. As a result, it was found that 8 companies and 11 models, including 3M, Mitsubishi, and Panasonic, had substandard product quality. The reporter also learned from the quality supervision department that the regulatory inspection of water purifiers mainly focuses on domestic big brands. The high failure rate of various types of activated carbon filter products found among them is due to reasons such as unqualified immersion tests for dissolved total solids, aluminum, and arsenic indicators.
In this regard, some experts in water purification equipment also pointed out that the service life of water purifier filters is only based on the water in a certain place as a standard, and this standard is certain
