Equipment will be warranted if certain conditions are met:

• The product still be within the warranty period.
• The damage must be confirmed by a Mitsubishi Cleansui technician as a manufacturer defec
• The product is not in cases of refusal to accept the warranty
• Warranty stamps and serial numbers must be intact, with no signs of scratches, erasing or fading
• The product only use tap water (according to QCVN 01-2018/BYT, water pressure from 0.07-0.35 Mpa, below 35 degrees Celsius, and above freezing temperature.

Consider using a water meter, especially in households or workplaces where multiple people share usage.

Water passes through 4 filtration layers (non-woven fabric, ion exchange fiber, activated carbon, hollow fiber membrane), removing all impurities, dust, mold, dissolved lead, residual chlorine and microplastics. Filtered water meets QCVN 6-1:2010/BYT standards. Therefore, it is rich in minerals and completely safe for drink directly. However, it is essential to ensure that tap water is treated at the factory. Boiling the water does not pose any danger or alter its properties, so you can use it without any concerns.

EU201 employs a water leakage prevention mechanism with an EUC2000 cartridge, reducing the risk of leaks by minimizing the number of cartridge units. Controlled by a locking valve at the faucet, the system ensures water enters cartridge only when needed, minimizing static water pressure on cartridge and pipeline.

This leakage prevention mechanism has been in use since 1990 and is consistently maintained for Cleansui’s high-end water purifiers. Statistics indicate that over 80% of under-sink water purifiers in Japanese apartments and condominiums use this mechanism.
