What Is Mitsubishi Cleansui?
Mitsubishi Cleansui is a water purifier from Mitsubishi Chemical Cleansui Corporation which is one of Japan’s leading chemical companies. The hallmark of Cleansui water purifiers is their use of Hollow Fiber Membrane technology which can filter out impurities as small as 0.01 micron more effectively than typical water purifiers on the market.
Mitsubishi Cleansui water purifiers are certified by NSF (National Sanitation Foundation), JIS (Japanese Industrial Standards) and ISO 9001 so you can be confident that the filtered water is clean and safe to drink.
Mitsubishi Cleansui Filtration Technology
Mitsubishi Cleansui uses Hollow Fiber Membrane Filter Cartridge which is highly effective at filtering out contaminants. It can remove:
- ✅ Bacteria and microorganisms
- ✅ Chlorine and residues from tap water
- ✅ Heavy metals such as lead and mercury
- ✅ Dirt and impurities in the water
At the same time, it retains essential minerals such as calcium and magnesium, which are good for your health. This sets it apart from RO (Reverse Osmosis) water purifiers, which tend to filter out everything, leaving no minerals behind.
