For a water purifier, one of the core components is the filter element. The safe operation of each filter element is a prerequisite for ensuring the safety and health of drinking water quality. If the filter element is not replaced for a long time, it will not only cause harm to the operation safety of the whole machine, but also cannot guarantee the safety of your drinking water, and it may not necessarily save money. Second, the filter element of the water purifier is overloaded, reducing the operating life of the whole machine. The principle that the filter element can filter the pollutants in the water is that they have a smaller pore size than the pollutants to retain the pollutants in the water, or adsorb the pollutants and different colors and odors through the activated carbon adsorption. If it is not cleaned and replaced in time, the whole water purifier will be overloaded, the filter element will be blocked, and the water flow will gradually decrease. Because of the blockage, the entire operation of the water purifier will become slow and sluggish in order to filter the pollutants in the water as much as possible, and the life of all components and filter elements will be shortened rapidly. Finally, the effect of the filter element is weakened, and the small loses the big, which damages the health. If the filter element of the water purifier is not replaced, the pollutants may be squeezed and blocked, the effect of the filter element will be weakened, and the filtering effect will not even be achieved. If consumers directly drink these polluted "filtered water", it is actually similar to drinking tap water, and may drink some harmful impurities into the body. Therefore, it is necessary to replace the filter element regularly and in time!
