The Bishuiyuan water purifier purchased by applying for Everbright Credit Card is the D401 super nanofiltration water purifier, which is the latest water purification product developed and produced by Beijing Bishuiyuan Water Purification Technology Co., Ltd.

Bishuiyuan super nanofiltration machine is completely different from traditional water purification equipment. It completely surpasses traditional water purifiers in the four aspects of "safety, health, water saving, and power saving". The two mainstream water purifiers currently on the market are ultrafiltration machines and reverse osmosis machines. The purification effect of the super nanofiltration machine is more obvious than that of the former, and it has achieved a leap in the safety of water quality. Compared with the latter's pure water, the super nanofiltration machine has achieved the same level of safety. Completely retains various trace minerals beneficial to health in the original water. In addition, the super nanofiltration machine does not consume electricity, and the wastewater ratio during the purification process is extremely low. The concept of energy conservation and environmental protection is particularly outstanding.

It should be said that the performance of this machine is quite good! ! !
