How to identify the quality of PP filter element

At home, the existence of a water purifier is indispensable. The first-stage filter element in the water purifier is made of PP cotton filter element. The first-stage filter element will not only directly affect the water quality, but also affect the subsequent third- or fourth-stage filtration effect. It is related to the life of the filter element, so the quality of the PP cotton filter element is very important for the water purifier. Before distinguishing whether the quality is good or bad, let's first understand the PP cotton filter element: Introduction of PP cotton filter element PP cotton filter element is a fiber filter element made of polypropylene (a kind of plastic raw material, also called PP material). It is dense and the filtration accuracy can reach 1m. It is mainly used to filter out impurities larger than 1m in tap water. In addition, the filtration process of the PP cotton filter element is from the outside to the inside. The closer to the inner layer of the filter element, the smaller the pore size. The filtering precision is also higher. Because the PP cotton filter element belongs to the first-stage filter element of the water purifier, most of the impurities will be filtered out at this stage, and the more impurities are filtered, the easier the filter element is to be blocked. Therefore, the life of the PP cotton filter element is very short. The area with poor water quality may need to replace the filter element in a short time, and the area with better water quality will not exceed six months. Therefore, if you buy a household water purifier with a PP cotton filter element, in order to avoid secondary pollution of the water purifier and affect the filtering effect of the filter element later, it is recommended that you replace the filter element every 3-6 months. Identify the quality of PP cotton filter The quality of PP cotton filter is determined by the tightness of its fibers. The internal fibers of a high-quality PP cotton filter are tight and uniform, and this difference cannot be seen with the naked eye when purchasing. So how should we distinguish? 1. Look at the weight. We can measure the weight with our hands. The heavier the weight, the higher the fiber density of the filter element. The quality is also better. 2. Look at compressibility. 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 hand feel, the stronger the hand feel, the better the compression performance.

Nowadays, it is very common for us to utilise in water filters. And the quality of is decisive to production efficiency.
