What Makes the Ecosoft CROSS Solo an Effective RO System?

The Ecosoft CROSS Solo uses advanced direct flow reverse osmosis technology to deliver powerful, on-demand water purification. At its core is a high-performance 2‑in‑1 filter cartridge that integrates a 500 GPD RO membrane with coconut shell carbon filtration, designed to remove up to 99% of contaminants, including PFAS, bacteria, viruses, chlorine, and heavy metals.

Advanced 2-in-1 Filtration Technology

  • Reverse Osmosis Membrane:

    Filters out dissolved solids, heavy metals, nitrates, and harmful substances.

  • Activated Carbon Postfilter:

    Enhances taste by removing residual chlorine, odours, and organic compounds.

The CROSS Solo produces purified water at a fast 1.3 L/min flow rate, with no storage tank needed. Its 50% recovery rate ensures efficient water use, reducing waste while maintaining high performance. For reliability and longevity, the system features automatic membrane flushing, helping prevent scale buildup. Plus, a built-in auto shut-off activates after 30 minutes of continuous use for added protection and peace of mind.

CROSS Solo Maintenance Guide

To maintain optimal performance, the CROSS Solo water filter requires periodic replacement of its filtration elements.

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 optimising the longevity and efficiency of your CROSS Solo reverse osmosis filter.
