5. Filtration System
The WD-M1 utilizes an advanced 6-stage Reverse Osmosis (RO) filtration system to ensure clean and great-tasting water. This system effectively removes rust, sediments, odors, and harmful substances such as TDS, chlorine, fluoride, lead, PFOA, PFOS, chloroform, and copper.

The 0.0001μm RO membrane ensures high purification accuracy, resulting in purer and tastier water, confirmed by third-party testing.
6. Maintenance
