As consumers pay more attention to health and drinking water safety issues, more and more households use water purification equipment as a standard for decoration. Moreover, the entire clean water consumption is presented as a single water purifier. Drinking water to solve the overall development trend of the program. Especially for large and villa users, drinking water to solve the overall plan of the group. As the front-end solution of the device, the role of pre-filter is also very critical.

One, on the pre-filter

Then the question is, probably many consumers don't know what a prefilter is.

In foreign markets, pre-filters are also called pipeline protectors or pipeline filters. In fact, both names are straightforward to explain its role: To filter impurities or protect waterways in the front section of the water pipe. Sounds, the former seems better understood.

The official explanation is: The pre-filter belongs to the product of total pipeline water purification. It is an impurity filter device that can filter 40-120 micron particle impurities to restore the impurity content in the water to the factory standard. It is usually installed. After the water meter, it can ensure that a large amount of precipitated impurities generated in the water supply pipe network will not cause harm to the human body, and the water pipe and wading equipment installed on the water pipe, such as water softener, water purifier, water purifier or direct drink Machines and solar water heaters, electric water heaters, gas water heaters, washing machines, etc. play an active pre-protection.

The pre-filter is usually composed of three parts: the head, the filter element and the filter cup. Although the three components seem to be simple, there are mysteries unknown to the general public. With advances in technology, pre-filters are no longer simple. The mechanical design, but added intelligent control, automatic flushing and other functions.

In addition, consumers may have doubts as to why foreign countries are called pipeline protectors to become pre-filters in China.
