How to buy a household water purifier

As the “heart” of the water purifier, the RO membrane directly determines the water quality and the cost of replacing the core (the price of a single unit is usually in the range of 50-120 U.S. dollars). But 90% of users do not know: scientific maintenance can make RO membrane life 1-2 years longer! Today we are from 5 key dimensions, hand in hand to teach you to guard this “water purification engine”.

After the membrane system has been running for a period of time, sometimes the treatment capacity decreases significantly and fails to reach the designed capacity. The reasons for this phenomenon are mainly related to the working environment of the membrane system, selection and design, installation and construction, operation and management, and the performance of membrane products.

Simply on the point of “drinking water”, whether it is filtered water from a water purifier or bottled water, there is not much difference. After all, it's all “H₂O”. The only difference is that the water inside the “impurities” (including minerals) is different. This difference is reflected in the type of impurities, the amount of a particular impurity.

Friends, how long has your water purifier filter not been changed? Is not think as long as there is clean water flow out, is equal to everything is fine? In fact, this idea really have to change! Because the water purifier is not a ‘perpetual motion machine’, the cartridge is its core components, once the overdue use, not only lose the filtering function, but also may become a breeding ground for bacteria.
