Service and maintenance

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 clean and dry replacement process. Thanks to this design, cartridge replacement takes less than 5 minutes and requires no tools.

For an easy cartridge replacement, check our video guide.

The CROSS Solo features automatic membrane flushing to prevent contamination and extend membrane lifespan. Additionally, an automatic shut-off function activates after 30 minutes of continuous operation, ensuring resource conservation and system stability.

This system is designed for use with high-quality tap water free of chlorine and turbidity.

How to improve morning water quality and enjoy great-tasting water anytime

To solve this issue and enhance your drinking water, we recommend installing the
Ecosoft Mineralizing Postfilter for RO systems (PD2010ECO).

Connect the postfilter between the “Drink” outlet of your reverse osmosis system and the purified water faucet, as shown in the diagram.

This solution is ideal for compact reverse osmosis filters, where purified water may slightly lose freshness overnight due to natural diffusion.

Thanks to its mixture of calcite and activated coconut shell carbon, this postfilter provides:

Post-filtration after the RO system
Additional mineralization of purified water
Improved taste and odor

Enjoy water that’s not only pure thanks to your ultra-compact reverse osmosis filter CROSS Solo, but also naturally refreshing and enriched with essential minerals.

Cartridge Replacement Notification

CROSS Solo is equipped with a smart indicator system that alerts you when a filter cartridge has reached the end of its service life:

The power indicator will start blinking.
All filter indicators will remain solid.
An audible alert will also sound:
- 10 beeps every hour
- 10 beeps each time you open the tap for water purification

These visual and audible signals indicate that it’s time to replace the cartridges.

After Cartridge Replacement

After installing the new cartridges, press and hold the “Restart” button for 5 seconds to reset the filter status. You will hear a single beep, confirming that the reset was successful and the system is ready for use.

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.
