Frequently asking

What are the product warranty terms?

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 defect
  • 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 01-1: 2018/ BYT), water pressure from 0.07-0.35 Mpa, below 35 degrees Celsius, and above freezing temperature.
  • The product is used properly voltage.
Can alkaline water be used regularly? If alkaline water is boiled, will it lose its properties?

You can consume alkaline water regularly at a suitable level for your body. In addition to natural minerals, alkaline water also contains dissolved hydrogen, a byproduct of the electrolysis process. This hydrogen is effective in reducing oxidative stress and offers various health benefits.

To understand effects on the properties of alkaline water when boiled, let’s examine its characteristics:

  • – Naturally rich in alkalinity
  • High levels of antioxidants (due to ultra-small H2 molecules)
  • Ultra-small water molecule cluster structure
  • Abundant natural minerals (as a result of the electrolysis process, alkaline water is richer in minerals compared to tap water)

However, it’s important to note that boiling alkaline water may impact some of its positive properties, specifically characteristics 2 and 4. The evaporation of H2 molecules and precipitation of natural minerals can occur at high temperatures. Consequently, certain beneficial aspects of alkaline water may be compromised during boiling.

EU301 has been utilized for more than a year, but "Replace Cartridge" indicator has not illuminated. Is it necessary to replace cartridge? Why does "Replace Cartridge" indicator light up in some instances, even when it hasn't been used for a year?

“Replace Cartridge” indicator has two expiration warning states:

  • Flashing light/red: EU301 has been operational for 346-365 days – Signaling that the cartridge is approaching expiration.
  • Solid light/red: EU301 has been operational for more than 366 days – Indicating the need to replace with a new cartridge.

If EU301 has been in use for over a year and the indicator hasn’t activated, there may have been power outages or unplugging. The device only counts time when it has power. Our customer care department will call to remind about the cartridge replacement time. Additionally, our technical department will also check to ensure the counter is functioning properly.

If the “Replace Cartridge” indicator lights up before one year of usage, please contact 1800 8171 (Southern) – 1800 8172 (Northern) (free of charge). Our technical staff will come for inspection and address any issues.

Is there any intermingling of these two water sources when the auxiliary faucet and main faucet simultaneously direct water into the sink? Can the auxiliary faucet be detached?

Customers are free to use water from both the main and auxiliary faucets for tasks such as washing vegetables or cleaning the sink. Nevertheless, it is not advisable to mix these two water sources for direct drinking, as the water from the auxiliary faucet may have an unstable pH.

It is crucial for customers not to remove the auxiliary faucet, as doing so may compromise the safety of the system and introduce the risk of bacterial contamination from the auxiliary faucet head into the cartridge.

Other brands use chemicals to clean electrode plates. I find that the polarity reversal mode of the EU301 is insufficient. Has Mitsubishi Cleansui intervened with chemicals? What is the substance, how is it done, how often, and how much does it cost?

Electrolysis tank has Titanium and Platinum electrode plates, five in total, processed tightly to produce water with different pH levels. EU301 has a self-cleaning mechanism to extend lifespan of electrode plates. However, within 2 years, if the pH levels of water are not achieved as initially, please contact Cleansui for cleaning electrolytic tank. Customers can rest assured because the chemical is extracted from lemons (citric acid).

Cleaning electrode plates should be done by Cleansui technical service. To avoid damage or unintended issues, customers should not attempt to open the device for cleaning.

Cleansui Vietnam is implementing the Cleansui Care (C-Care) service to care for EU301. However, the scope of application is currently limited in some areas. For details, please contact Cleansui Vietnam at:
