How to identify the quality of pp membrane filter
The pp membrane filter in the water purifier uses a PP cotton filter. The first-stage filter will directly affect the water quality, and it will also affect the subsequent three-stage or four-stage filtration effect and the life of the filter. Therefore, the quality of the PP cotton filter is Very important. Before distinguishing the quality, you need to understand the PP cotton filter
Since the pp membrane filter element is the first element of the water purifier, most of the impurities will be filtered at this stage, and the more impurities filtered, the easier the filter element will be blocked. So the life span of PP cotton filter is very short, the area with poor water quality may need to be replaced in a short time, and the area with better water quality will not exceed six months.
How to identify the quality of the pp membrane filter, the quality of the PP cotton filter is determined by the tightness of the fiber, and the internal fibers of the high-quality PP cotton filter are tight and uniform. This difference cannot be seen with the naked eye when buying. So how can we tell? 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. Look at compression. Generally, the higher the fiber density of the filter element.
