The water purifier is really useful, which can purify the water. It can effectively intercept the visible and invisible substances in the water, including minerals and heavy metals. Therefore, whether in theory or in practice, the role of water purifier in purifying water quality cannot be denied. If it has no purification function, then it has no value of existence.
The water purifier usually refers to a small filter used for family use. Its technical core is the filter membrane in the filter element device. At present, the main technologies come from ultrafiltration membrane and RO reverse osmosis membrane.
The water purifier can effectively filter out rust, sand, colloid and adsorb residual chlorine, odor, abnormal color, pesticides and other chemicals in water. It can effectively remove bacteria, impurities, toxins, heavy metals and so on in water.
Misunderstanding of water purifier purchase
1, the more filter elements, the better: the more filter elements are not the better. Some low-end water purification products have four or five filter elements at every turn, but they all use simple filter materials, and the filtering effect may not be as good as that of a high-performance filter element.
2, just look at the brand regardless of professionalism: the complexity of household water purification, especially direct drinking water, is a team that needs professional research and development, so everyone should try to choose the brand of water purification equipment made by professional water purification enterprises, which will not only guarantee the technical quality, but also provide you with more professional services.
3, the filter element can not be changed for a long time: in fact, the filter element that will be blocked is a good filter element, which also shows that the water purifier is really effective. It is often exaggerated to claim that the filter element will not be replaced for 3~5 years in the market. Don't pursue cheap ones too much. The life of high-quality filter elements and the amount of clean water will be better, and the price will naturally go up. But the overall calculation is still cost-effective.
