CROSS 90 Balance filter uses a three-stage water purification system that effectively removes impurities, including bacteria, viruses, and harmful chemicals. The main filtration stages are described below: 

Composite polypropylene and carbon block filter 

In the first stage, water passes through a filter that traps sediment such as sand and rust, while also reducing chlorine content, organic compounds, and petrochemicals. This provides basic water purification and prepares it for the next stages. 

Reverse osmosis membrane (600 GPD) 

In the second stage, water undergoes molecular purification through a reverse osmosis membrane, which removes up to 99.8% of impurities, including bacteria and viruses. This process ensures the highest level of water purity. 

Carbon block & mineralizing postfilter 

The final stage involves passing water through an activated carbon postfilter, which improves the taste and odor of the water, providing final purification before consumption. Mineral fortification: adds calcium for improved taste and health benefits.

Smart indication and features of CROSS 90 Balance filter 

Indication of replacement filters condition 

CROSS 90 Balance filter system is equipped with a smart color-coded indicator on both the faucet and the front panel. This feature serves as a convenient reminder to change the replacement filters. 

• Green light: Indicates that the filter's capacity is sufficient. 
• Purple light: Signals that the filter's capacity is running low, prompting preparation for replacement. 
• Red light: Alerts that the filter's capacity is exhausted and immediate replacement is required. 

An additional sound indication complements this system: one short beep indicates the capacity is running out, and two short beeps signal that replacement is necessary. 

Indication of purified water quality 

The smart color indicator also monitors and reflects the quality of the purified water. Any deterioration in water quality triggers a warning, ensuring that users are aware when it's time to replace the filters to maintain optimal water purity. 

Smart functions 

• Membrane auto flushing: To enhance the membrane's lifespan and maintain high purification efficiency, the CROSS90 Balance automatically flushes the membrane at each connection to the network, 5 minutes after each water intake, and after a 12-hour standby period. 
• Leakage protection: If any leaks are detected inside the filter, the system will automatically shut off the inlet water to prevent any damage or flooding. 
• Not-closed faucet indication: If the faucet is left open for 30 minutes, the filter will emit a sound signal. If the faucet remains open, the system will automatically shut off the inlet water 3 minutes after the buzzer sounds, effectively preventing potential flooding.
