Filtration
4 filtration layers in one high-performance cartridge
Mitsubishi Cleansui's filtration technology removes up to 17 groups of harmful impurities. Four filtration stages in one cartridge suit the quality of tap water in Thailand — above all the hollow fiber membrane, which removes impurities and microscopic bacteria that conventional activated carbon cannot.
-
1Non-woven fabric
Non-woven mesh fabric
Removes coarse impurities and insoluble suspended solids. Its 3D structure removes suspended solids and impurities as large as 0.01 mm without using chemicals, ensuring water quality safety.
-
2Activated carbon and special ceramic
Activated carbon and special ceramic
Removes dissolved lead. Efficiently adsorbs residual chlorine, organic compounds, pesticides and unpleasant odors while preserving the natural mineral content of tap water. Mitsubishi Cleansui's activated carbon has an adsorption capacity three times greater than ordinary activated carbon on the market.
-
3Hollow fiber membrane
Hollow fiber membrane
Water passes from the outside of the hollow fibers through millions of ultra-small 0.01-micron pores into the fiber. Impurities as small as 0.01 micron — algae, microorganisms, bacteria, turbidity and metal particles — are removed, while clean water and natural minerals such as Na⁺, K⁺, Mg²⁺ and Ca²⁺ pass through, giving clean, delicious water that keeps its minerals.
SUPER HIGH GRADE
Removes 17 substances
A SUPER HIGH GRADE cartridge removes up to 17 substances found in tap water:
Turbidity and chlorine
- 1
Turbidity Turbidity
Sediment carried in the water, such as rust, mercury and bacteria, is filtered out completely.
- 2
Chlorine Free residual chlorine
Used to kill bacteria and microorganisms in the water, but it spoils the taste.
Industrial and agricultural chemicals
- 3
Trichloroethylene Trichloroethylene
An industrial chemical that affects liver and kidney function; a carcinogen.
- 4
Tetrachloroethylene Tetrachloroethylene
An industrial chemical that affects liver and kidney function; a carcinogen.
- 5
1,1,1-Trichloroethane 1,1,1-Trichloroethane
An industrial chemical that affects liver and kidney function; a carcinogen.
- 6
Benzene Benzene
A liquid chemical that is highly flammable.
- 7
Phenols Phenols
A corrosive, flammable toxin used to make plastics.
- 8
Anionic surfactants Anionic surfactants
Widely used in cleaning products — cheap, foamy and good at removing grease, but very irritating.
- 9
Agricultural chemicals CAT (agricultural chemicals)
Pesticides that seep in from farming that puts quantity ahead of quality.
Trihalomethanes (THMs)
- 10
Trihalomethanes Trihalomethanes
Organic matter in tap water combined with chlorine; a carcinogen.
- 11
Chloroform Chloroform
A type of trihalomethane, and a carcinogen
- 12
Bromodichloromethane Bromodichloromethane
A type of trihalomethane, and a carcinogen
- 13
Dibromochloromethane Dibromochloromethane
A type of trihalomethane, and a carcinogen
- 14
Bromoform Bromoform
A type of trihalomethane, and a carcinogen
Heavy metal and odors
- 15
Soluble lead Soluble lead
Harmful to health; it can pass to an unborn baby and affect learning development.
- 16
Musty odor (2-MIB) 2-MIB (musty odour)
Removes unpleasant odors from water
- 17
Geosmin Geosmin
A natural organic compound released by mold-like bacteria.
Membrane
A high-quality membrane
Cleansui's hollow fiber membrane filters water thoroughly clean. In 1984 Mitsubishi Chemical (then Mitsubishi Rayon) developed a ground-breaking hollow fiber membrane that removes bacteria and rust remarkably well. Today it is highly regarded as a precise filtration membrane and widely used in water purification plants, disinfectant production and medical water.
-
0.01 µm
The secret of advanced removal
The wall of the hollow fiber (polyethylene) efficiently removes particles larger than 0.01 micron (1/100,000 mm), bacteria and iron rust from tap water.
-
4–6 µm
Removes Cryptosporidium
Cryptosporidium measures 4–6 microns, and the hollow fiber membrane removes particles larger than 0.01 micron. Multiplying in the small intestine, it causes stomach pain, fever and severe diarrhea, and chlorine does not kill it.
-
Red rust
Removes red rust
Efficiently removes the red rust often found in the pipes of older buildings.
-
Less clogging
Why it clogs less
The hollow fiber has a mesh-like structure, so it filters not only at the wall but through its inner surface too. That structure is why it clogs less than other makers' membranes.
