There are many types of water purifiers, the pre-filter should be a more special water purifier, its water purification effect can be said to be the worst of all water purifiers, there is no heating function. But this water purifier is loved by many consumers, why is this?
Although the pre-filter can not achieve the effect of direct drinking, can not soften hard water, and does not regulate the water temperature, it can well intercept large particles of impurities in the water, such as sediment, rust and so on. In this way, there is no need to worry about the impurities in the water will cause the risk of blockage in the washing machine and dishwasher at home, and it can also reduce the workload of other water purification equipment in the home and extend the service life of the filter element. In addition, the front water purifier has many advantages, its small size does not occupy the place is easy to install, more importantly, the price is favorable, the market dozens to hundreds of front filters are available. However, choosing a pre-filter with good quality and good function is not a simple thing, you need to pay attention to the following 4 points!
First, expensive is not necessarily good
The market price of the pre-filter is from tens to thousands, as the saying goes, a penny is a penny, and the pre-filter of dozens of dollars takes into account the quality, and it is indeed not recommended for everyone to buy. There are water purifiers that sell thousands of yuan on the market, we don't think that the price is high, the pre-filter is a water purifier with a very simple structure, its main role is to carry out coarse filtration, so there is no need to spend too much cost. The quality of the water purifier on the market for a few hundred dollars is very good. Regarding the pre-filter, I hope that everyone has a general understanding of its price and do not blindly choose expensive.
Second, understand the pressure range of the pre-filter
I believe that many small partners have seen the news of the explosion pipe after the installation of the pre-filter, and the burst pipe has a lot to do with the pressure bearing capacity of the water purifier in addition to the quality problem of the water purifier itself. Therefore, it is recommended that you first understand the water pressure of tap water at home and then choose the appropriate pressure strength of the front filter. Or you can choose a front-mounted filter with a pressure gauge to keep an eye on the water pressure.
Third, choose a good quality pre-filter
The structure of the front filter is simple, mainly the interface, the barrel, the filter of these three parts, in the purchase of the pre-filter is recommended to choose the interface is pure copper material, the barrel is explosion-proof and pressure-resistant material, the filter is best 316 stainless steel material.
Fourth, the accuracy of the pre-filter should not be too high
The higher the accuracy, although the better the filtration effect, but because the pre-filter is a coarse filter device, if the accuracy is too high, it is easy to cause clogging. Generally, the household pre-filter can choose about 40 microns, which will not affect the water flow but also effectively intercept the large particle impurities in the water.
Epilogue:
Although the water purification effect of the front water purifier is not the best or even not too large, its protective effect on other water purifier devices and home appliances in the home cannot be ignored. Especially in areas with water quality deviations, the convenience of the pre-filter can be clearly felt.
