Frequently Asked Questions (FAQ)

Does the system waste a lot of water?

No. The pure/drain ratio is 2:1 — for every 2 cups of pure water, only 1 cup of drain water is produced.

How often should I replace the filter?

The composite filter has a lifespan of 12 months or 6,000 liters. Color change in the system and on the faucet indicates the filter status.

Is filter replacement easy?

Yes. The twist-and-pull design allows you to replace the filter without turning off the water or power.

Can I get hot water immediately after setting the temperature?

After setting the desired temperature and the heating indicator turns off, you can get hot water. It takes about 15 minutes to heat from ambient temperature to 95°C. Set the temperature in advance so you don't have to wait.

Can I turn off the heating module when it's not needed?

Yes. Simply turn off the heating switch on the system and turn it back on when needed.

Is the system safe?

Yes. The K6 includes child safety lock, dispensing temperature indication, flow meter, NTC, and overheat protection to prevent burns and dry operation.
