CROSS Solo Reverse Osmosis Filter

In a context where tap water quality becomes a major concern (taste, odors, pollutants, PFAS, etc.), choosing a high-performance purification system is essential. With the Cross Solo, Ecosoft offers a direct-flow osmosis system that is intelligent and capable of providing drinking water immediately, without a bulky tank, while guaranteeing efficiency and safety.

Why choose a direct-flow osmosis system?

• Ultra-pure water on demand: no need to store, water is filtered on demand, which reduces risks of stagnation or secondary contamination.

• High sanitary quality: elimination of contaminants (bacteria, viruses, PFAS, heavy metals, etc.).

• Improved taste and smell: removal of chlorine, odors, and unwanted tastes.

• Simpler maintenance than a storage system; less space required.

Technical characteristics & specifics

• Purification flow rate: approximately 1.5 L/min or ~90 L/h for similar models.

• Recovery rate: > 50% (this is the amount of useful treated water vs water rejected).

• Quality of filtered water: TDS (total dissolved solids) reduced to a low range (ex. 5‑15 ppm) depending on the model.

• Inlet pressure: typically between 2‑5 bar.

• Dimensions & footprint: comparable models are quite compact (ex: ~ 435 × 140 × 458 mm, weight ~ 11 kg) which allows installation under a sink.

• Smart functions:

  • Filter change indicator (visual / audible).

  • Automatic membrane rinsing (after use, after inactivity period).

  • Leak protection, automatic shutdown in case of problems.

• Source water requirements: pH between ~ 6.5‑8.5 ; maximum TDS of inlet water up to ~ 1500 ppm in comparable cases.

The advantages of the Cross Solo

• High performance: intense purification thanks to quality RO membrane, significant pollutant removal, PFAS included.

• Comfortable flow rate for daily use (kitchen, direct consumption).

• Simplified maintenance thanks to indicators, easy filter replacement, automatic rinsing.

• Space saving: slim design: under-sink installation is possible without monopolizing space.

• Safety and reliability: anti-leak protection system, water quality monitoring, warnings.

Who is this model for?

• Households wishing for purified water on demand (drinking, cooking).

• People sensitive to water quality (taste, health, possible presence of contaminants).

• Homes with limited under-sink space, but concerned with performance.

• Those who want an automated device, with less manual maintenance.
