After the reform and opening up, along with the rapid development of the city, industrial pollution, agricultural pollution, and domestic pollution have brought great threats to our domestic water. The Chinese Academy of Sciences issued a national study report: 436 of China's 532 rivers It is subject to different degrees of pollution. At present, there are about 190 million people in rural China who have excessive levels of harmful substances in drinking water. The concentrated discharge of sewage in cities is seriously exceeding the self-purification ability of water bodies. Water pollution has become an invisible killer of human health.
Water purifiers are becoming an indispensable part of home appliances. However, many families do not know enough about water purifiers. They have to say that diligence and thrift is a good habit of the Chinese nation. However, many families have excessive savings and feel that it is troublesome to replace the filter. And costly, two or more years have not replaced the filter or other normal maintenance, resulting in the more dirty and dirty water purifiers but I do not know. The following small series from the time to give you a general knowledge of the replacement of water purifier filter:
As people's health awareness increases, the number of households installing water purifiers is increasing. As we all know, the filter element is the core of the water purifier, which is responsible for filtering out rust, sediment, heavy metals, bacteria, residual chlorine and harmful to the human body. Heavy metal, to protect the body healthier and safer. The water purifier also needs regular maintenance. The filter element of the water purifier needs to be replaced regularly, so as to fully guarantee the purifying effect of the water purifier. Otherwise it will become secondary pollution.
(1) will reduce pure water effluent
The filter element works for a long time, and the filter element filled with pollutants causes clogging, which not only reduces the amount of pure water flowing out, but also greatly reduces the filtration effect, which also causes the wastewater generated by the water purifier to increase, thereby increasing the cost.
(2) Shorten the life of the RO filter
Long-term non-replacement of the filter element to overload it, due to blockage, some activated carbon that is not responsible for filtering large particle impurities must bear this external burden. Especially for RO water purifier, the core RO reverse osmosis membrane The replacement cost is quite high. The replacement of the primary membrane is not timely, and the life of the reverse osmosis membrane is seriously reduced. Because the filter cartridge is not replaced in time, the RO membrane filter is clogged and the RO membrane needs to be replaced, and the RO membrane filter costs are high. It will lead to an increase in costs.
Perhaps, you only have to bear the replacement cost of 'PP cotton filter', just because of the bad habit of 'changing the filter element irregularly', you need to bear the double cost of two filter elements, and even more.
Answer: It is not possible.
The water purifier filter must be replaced regularly. Everything has its service life. If the filter element is replaced in an overdue period, there is no doubt that the water quality begins to deteriorate. To ensure the safety of drinking water, it is the best policy to replace the filter element regularly!
Some people may say: 'Since it is so dirty, I still don't need a water purifier.'
But why not think about it in reverse: 'The filter cartridges are so dirty, how dirty is our water?!'
In fact, as long as the filter element is replaced regularly, the water purifier is still the first clean baby! In the United States, the installation rate of water purifiers is 90%, and most families have a clear sense of health, regularly replace the filter to ensure the water quality in the home. Lasting security.
The answer is: Nothing so far. The filter element is a consumable item, just like a printer cartridge, it needs to be replaced when it is used up.
The water purifier is generally filtered by a combination of several filter elements. Each filter has a certain service life. When you feel that the purified water is getting smaller, see if the filter is obviously colored or the water purifier is getting worse. I have to replace the filter.
Therefore, through the above introduction, we can understand that whether we are from a health point of view or an economic point of view, it is very important to regularly replace the water filter of the water purifier in our home.
