CROSS Solo uses advanced reverse osmosis technology to ensure high-quality water purification. The system operates through a 2-in-1 replacement filter, combining a 500 GPD RO membrane and coconut-based carbon filtration to remove 99% of contaminants, including bacteria, viruses, and PFAS.

Filtration Process:

1. Reverse osmosis membrane – Eliminates dissolved salts, heavy metals, and harmful substances.
2. Carbon postfilter – Removes odors, and organic impurities, improving taste.

CROSS Solo direct flow reverse osmosis system provides a seamless water purification experience with its direct flow technology, delivering 1.3 L/min of purified water instantly. The system optimizes resource use with a 50% recovery rate, reducing water waste while maintaining efficiency. To ensure long-term performance, it features automatic membrane flushing, preventing buildup and extending the membrane’s lifespan. For added safety, the system includes an auto shut-off function, which turns off operation after 30 minutes of continuous use.

Flushing Modes

• After connecting to the power supply
• After 5 minutes of use
• After 24 hours of standby
