In fact, many direct drinking machines used now can fully purify the water quality when they are used. In fact, it depends on the water purification effect of the direct drinking machine or the quality of the filter element used inside. Usually, home direct drinking machines have four filter elements. The front RO membrane filter element can remove impurities in water, and the back activated carbon filter element can remove peculiar smell and abnormal color in water, and at the same time, it can adjust the taste of purified water. After that, the ultrafiltration membrane filter core can intercept and remove the tiny suspended solids and bacteria remaining in the water, and the final post-activated carbon can effectively improve the purified water quality and let you drink the purest and healthiest water. ?
