What is reverse osmosis water systems?

Reverse osmosis (RO) is a water purification process that uses a partially permeable membrane to filter out impurities from drinking water. In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property that is driven by chemical potential differences of the solvent, a thermodynamic parameter. The result is that the solute is retained on the pressurized side of the membrane and the pure water is allowed to pass to the other side. To be "selective", this membrane should not allow large molecules or ions through the pores, but should allow filtered clean water to pass freely.

How does a reverse osmosis system work?

A reverse osmosis system reduces sediment and chlorine from water with a prefilter before it forces water through a semipermeable membrane to reduce dissolved solids. After water exits the RO membrane, it passes through a postfilter to filter the drinking water before it enters a faucet.

How often do I need to change the RO filter?

G3: The CF filter has a 6-month lifetime; the CB filter has a 1-year lifetime; the RO filter has a 2-year lifetime. Waterdrop G3 Reverse Osmosis System has a smart faucet and filter life indicators that will remind you to replace the filter.

When you change filters, do you need to turn the water off?

The water source and power supply are not required to be cut off when the filters need to be replaced. The replacements can be directly screwed and reinstalled. RO system can be normally used after resetting and the flushing process are finished.

Why is the RO remineralization filter necessary?

Because reverse osmosis water filtration system has a high filtration accuracy, leaving no minerals in the filtered water. While drinking mineral water is beneficial for human body, so MNR35 RO remineralization filter is a perfect add-on filter offering fresh and beneficial water.

Kind notice
Please refer to this diagram and be informed that you need to drill a hole on your countertop to place the smart faucet (No need for this step if your countertop already has a hole). Besides, an adapter will be installed on your household water tubing to connect to RO system’s wastewater tubing and input water tubing.
Electricity is required to run the RO system.
We do not recommend using well water as source for our RO systems. We do not recommend connecting tankless RO to a refrigerator or ice maker.
It's highly recommended to install our RO system with components provided by Waterdrop. Installing the system with any parts or accessories that are not provided by Waterdrop may cause the system to malfunction or shorten the lifetime of the system/filters.
