CROSS Solo is an ultra-compact and efficient direct-flow reverse osmosis system, perfect for drinking and cooking. Designed to fit even in the smallest spaces, it delivers instant access to pure water while optimizing resource use with 50% recovery technology.
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:
- Reverse osmosis membrane – Eliminates dissolved salts, heavy metals, and harmful substances.
- 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.

Cartridge replacement frequency
Membrane element & carbon filter for CROSS Solo: Replace every 12 months.
Replacing the cartridges is quick and straightforward, requiring only a simple twist-and-lock mechanism. The filter automatically shuts off the water flow when the cartridge is removed, ensuring a dry and clean replacement process.
CROSS Solo features automatic membrane flushing to prevent contamination and extend membrane lifespan. Additionally, an automatic shut-off function activates after 120 minutes of continuous operation, ensuring resource conservation and system stability.
Important usage tip: We recommend discarding the first two glasses of water in the morning or using them to water plants. Due to natural diffusion during overnight downtime, the quality of the purified water may slightly deteriorate.
Regular maintenance with timely cartridge replacements will ensure continuous access to pure, fresh water while optimizing the longevity and efficiency of your CROSS Solo reverse osmosis filter.
