How does the whole house water purification project distinguish the quality of the filter of the domestic water purifier?


Most domestic water purifiers or pure water machines use PP cotton filter as the first-stage filter. The first-stage filter will not only directly affect the water quality, but also affect the subsequent three-stage or four-stage filter effect and filter. Life, so the quality of PP cotton filter is particularly important for water purifiers. Before distinguishing the quality, the whole house water purification project first understand the PP cotton filter:

PP cotton filter is a fiber filter made of polypropylene (a plastic material, also called PP material). The diameter of PP cotton filter is uniform and dense. The highest precision of filtering is 1μm, which is mainly used for impurities greater than 1μm in tap water. Filter it out. In addition, the filtering process of PP cotton filter is filtered from the outside to the inside. The closer to the inner layer of the filter, the smaller the pore size. The higher the filtering accuracy. Because the PP cotton filter belongs to the first-stage filter of the water purifier, more than 80% of impurities will be filtered at this stage, and the more impurities filtered, the easier the filter will be blocked. Therefore, the life span of PP cotton filter is very short. The filter element may need to be replaced in more than two months in areas with poor water quality, and the longest area will not exceed six months. Therefore, if you have a PP cotton filter in your household water purifier, in order to avoid secondary pollution of the water purifier and affect the subsequent filtering effect of the filter, it is recommended that you replace the filter every 3-6 months.

The quality of the PP cotton filter is determined by the tightness of its fibers. The fibers inside the high-quality PP cotton filter are tight and uniform, and this difference cannot be seen with the naked eye when buying. How can we tell?

First: look at the weight. We can measure the weight with our hands. The heavier the fiber density of the filter element is. The better the quality.

Second: Look at compression. Generally, the higher the fiber density of the filter element. The better the compression performance, the better the quality of the PP cotton filter. We can judge by the feel of the hand. The stronger the feel, the better the compression performance.

The above two points may not be usable when we buy a new water purifier, but we can come in handy when we buy a PP cotton filter replacement separately.

There are four sizes of PP cotton filter elements for whole house water purification projects , which are 10 inches, 20 inches, 30 inches, and 40 inches. When we buy and replace PP cotton filters for water purifiers, please be sure to understand the original PP Size of cotton filter. Just buy the same size as the original size.
