Yiai water purifier: poor pre-filter effect and high sales, it is the marketing of the business Routine?
Pre-filter is a kind of water purification equipment. Among many household water purification equipment, the water purification effect of the pre-filter is not very significant, but its sales have been high. Why do so many people choose to install such a device without obvious water purification effect? Is this a business marketing trick? So is it necessary to install a pre-filter? Yiai Xiaobian will come to analyze the actual truth of this water purification equipment with you today, and avoid installation mistakes!
Pre-filter can only play a role in rough filtration of water quality, and its filtration effect is much worse than that of reverse osmosis water purifier or ultrafiltration machine. The filtration accuracy of the pre-filter is 40 microns, which can filter and intercept larger particles of impurities. Some people think that wrapping gauze in the faucet can also play such a role, so why install a pre-filter?
First of all, we need to have an in-depth and comprehensive understanding of the pre-filter. The pre-filter is generally installed at the front end of the household water supply system and is the first protective barrier of the whole house water system. By intercepting large particles in the water, it can reduce the probability of clogging of pipes and filter elements, and also reduce the rate of water purification. The replacement frequency of the filter element of the machine reduces the cost of use. Therefore, we can say that the main function of the pre-filter is to protect the water-wading appliances and other water purification equipment in the home, reduce equipment blockage and wear, and prolong the service life.
We need to understand not only the main role of pre-filters, but also There are a few points that need to be paid attention to, so as not to be misled.
First, if you have requirements for the quality of daily drinking water at home, you need to install a reverse osmosis water purifier or an ultrafiltration machine with a pre-filter, so as to achieve water purification effect. After all, the coarse filtration function of the pre-filter is more to protect rather than purify water.
Secondly, the filtration precision of the pre-filter should be about 40 microns. Do not blindly pursue high-precision filtration. For the pre-filter, It is not that the higher the accuracy, the better, as long as it can intercept large particles of impurities, and can ensure the best water flow speed.
Third, it is necessary to choose a reliable professional water purification brand to avoid poor quality products affecting water use due to quality problems. The front interface should be made of pure copper, preferably with backwash function, and it needs to be able to withstand pressure and explosion, and can withstand low temperature.
All in all, the pre-filter is not a tasteless product, but a practical Products that help us and improve the quality of household water, so Yiai Xiaobian recommends that everyone install a pre-filter at home, so that you don’t have to worry about other water-wading appliances being worn by impurities.
