The Mitsubishi Cleansui EU301 is an alkaline ionizer water purifier manufactured in Japan by Mitsubishi Chemical Cleansui, a member of the Mitsubishi Chemical Holdings Group. The biggest difference between the EU301 and conventional water purifiers is its ability to both purify water and electrolyze it into various types of water with different pH levels – from alkaline ionized water for drinking and cooking to slightly acidic water for skincare.

The EU301 is also the only model in the Cleansui line that can be installed under the sink, maintaining a neat and aesthetically pleasing kitchen space while still providing pure water directly from the tap.

1. Alkaline ion electrolysis technology inside EU301

• Electrolysis cell with 5 platinum-coated titanium electrodes.

At the heart of the EU301 is the electrolysis cell, consisting of 5 electrodes made from titanium coated with platinum – two materials with high chemical inertness that do not react with water, helping the water after electrolysis maintain a stable pH without producing additional chemical impurities.

The electrodes have a lifespan of up to 12 years, and the machine has an automatic electrode cleaning mechanism after each use cycle: after using approximately 10 liters of electrolyzed water and stopping for 30 minutes, the electrode plates will be automatically cleaned, with a flashing indicator light while the machine is performing this cycle.

• Mechanism of water molecule separation and restructuring

When an electric current passes through the electrolysis cell, the minerals dissolved in the water (calcium, magnesium, etc.) move towards the negative electrode, creating alkaline ionized water rich in minerals that are beneficial to health.

Conversely, acidic water is produced at the anode. Alkaline ionized water and acidic water are then discharged through two separate pipes on the faucet, ensuring they do not mix.

2. 6 water modes and practical applications

This is perhaps the most interesting aspect for many when learning about the EU301: the machine produces six types of water with different pH levels, each serving a specific purpose in daily life.

Alkaline ionized water at levels 1-3 is considered suitable for daily consumption because it is rich in natural alkalinity similar to that found in green vegetables, helping to neutralize excess acid and support digestion. Meanwhile, strongly alkaline ionized water and mildly acidic water are designed for more specialized uses and are not intended for direct drinking.

3. Four-stage filtration system - EUC2000 filter cartridge

Before water enters the electrolysis unit, the EU301 uses the EUC2000 filter cartridge with 4 consecutive filtration layers, requiring no electricity and producing no wastewater during the pre-filtration process.

1. Non-woven mesh fabric layer - coarse filter, removes large particles and impurities.
2. Ion exchange fiber layer - removes dissolved lead from water
3. Activated carbon layer - absorbs residual chlorine, organic compounds, pesticides, eliminates moldy odors and some compounds such as Bromoform, Trihalomethanes, Chloroform, Trichloroethylene, Bromodichloromethane. Cleansui activated carbon's absorption capacity is three times better than conventional activated carbon on the market.
4. Hollow fiber membranes allow water to permeate through millions of ultra-fine pores measuring 0.01-0.1 micrometers, retaining algae, microorganisms, bacteria, rust, mold, and heavy metals, while preserving beneficial minerals.

The EUC2000 filter cartridge has a lifespan of approximately 8,000 liters of water, equivalent to about 12 months of use with an average consumption of 20 liters/day.

The EU301 is installed under the sink and connected to the domestic water supply via a separate main faucet mounted on the kitchen countertop. It is suitable for households that frequently need direct drinking water and want to keep their kitchen tidy, free from bulky, space-consuming appliances.

Frequently Asked Questions About Mitsubishi Cleansui EU301

Is alkaline ionized water from the EU301 safe to drink directly? Yes. The neutral water (pH 7.0) and alkaline ionized water modes 1-3 (pH 8.0 - 10.0) are both suitable for direct drinking from the tap. However, the strong alkaline ionized water mode (pH 9.5 - 10.5) and mildly acidic water mode (pH 5.0 - 6.5) are not recommended for direct drinking and are only intended for food preparation and skincare purposes.

How often should the EUC2000 filter cartridge be replaced? The filter cartridge has a lifespan of approximately 8,000 liters of water, equivalent to about 12 months of use at an average consumption of 20 liters/day. The machine has an automatic indicator light when the filter needs replacing.

Do the electrodes need frequent replacement? No. The platinum-coated titanium electrodes have a lifespan of up to 12 years and are automatically cleaned after each use, so virtually no manual maintenance is required over the long term.

Is the EU301 suitable for small kitchens? Absolutely. This is the only model in the Cleansui range designed to be installed flush under the sink, saving countertop space.

Does the machine require continuous power? Yes, the EU301 requires a 220V-240V power supply to operate the electrolysis process, with a maximum power consumption of approximately 250W and only about 0.5W in standby mode.
