*It is not recommend to use well water as the source of RO system, or connecting a tankless RO system to a refrigerator or ice maker.
It is strongly recommended to use the components provided by Waterdrop to install RO system. Installing the system with any parts or accessories not supplied by Waterdrop may cause system failure or shorten the service life of the system / filter.


Smart Flushing
The elegant Waterdrop reverse osmosis system changes the connector of traditional internal water tubing, into the design of integral waterway which forms an isolation barrier to reduce the breeding of bacteria.
Automatic flushing without operation for 3 hours, the filter is always pure, bringing better purification enjoyment.
Improve bone health and help prevent diseases such as reducing post-menopausal bone density.
Lowers bad cholesterol:
Lowers harmful cholesterol due to its magnesium and potassium content to protect your heart.
Promotes digestion:
Help digestion by increasing the amylase secretion from the pancreas with its sulfate content.
Beautiful sink:
Its rich mineral content It moisturizes the skin and delays wrinkles.
