How it works
CROSS SOLO uses advanced reverse osmosis technology to provide high-quality water purification. The system works using a 2-in-1 replacement filter that combines 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 – Removes dissolved salts, heavy metals, and harmful substances.
Carbon post-filter – Removes odors and organic impurities, improving taste.
The CROSS SOLO direct-flow reverse osmosis system provides a seamless water purification experience with its direct-flow technology, instantly delivering 1.3 l/min of purified water. The system optimizes resource utilization with a 50% recovery rate, reducing water waste while maintaining efficiency. To ensure long-lasting performance, it features automatic membrane flushing, which prevents build-up and extends membrane life. For added safety, the system includes an automatic shut-off feature that shuts off after 30 minutes of continuous use.

Service
To To maintain optimal performance, the CROSS SOLO water filter requires periodic replacement of its filter elements.
Cartridge replacement frequency
Membrane element and carbon filter CROSS SOLO: replace every 12 months.
Replacing the cartridges is quick and easy, 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.
The CROSS SOLO has an automatic membrane rinse to prevent contamination and extend the life of the membrane. In addition, after 120 minutes of continuous operation, the automatic shut-off function is activated, ensuring resource conservation and system stability.
Important usage tip: We recommend pouring the first two glasses of water in the morning or using it to water plants. Due to natural diffusion, the quality of the purified water may deteriorate slightly during overnight downtime.
Regular maintenance with timely cartridge replacement will ensure continuous access to clean, fresh water while optimizing the longevity and efficiency of your CROSS Solo reverse osmosis filter.
