Cleansui, the trusted brand of instant water purifiers in Japan

Removes contaminants but leaves healthy minerals intact.

CLEANSUI’s original proprietary filtration system ensures the high level of performance. The special ceramic filter removes soluble lead, apart from other contaminants. (Insoluble lead can be removed by the hollow fibre membrane filter.)

  1. Ceramic

    The special ceramic filter removes soluble lead, apart from other contaminants. (Insoluble lead can be removed by the hollow fibre membrane filter.)

  2. Anti-bacterial activated carbon

    The activated carbon filter reduces unpleasant odors, chlorine and mould (2-MIB) from your drinking water. It also successfully removes pesticides, herbicides, CAT, Volatile Organic Compounds (VOCs) such as total trihalomethanes (chloroform, bromodichloromethane, dibromochloromethane, bromoform), tetrachloroethylene, trichloroethylene, 1,1,1-trichloroethane, etc.

  3. Hollow fibre membrane filter

    The core competency of CLEANSUI, the hollow fibre membrane filter, is made of ultra-fine polyethylene. The sidewalls can remove minute particles (as small as 0.1 micrometer) from tap water - including bacteria, algae, fungi, micro-organisms, cysts, cryptosporidium, and metal particles such as rust, lead, etc.

Advanced technology

The microporous hollow fibre membrane is a sophisticated fi lter developed by Mitsubishi Rayon’s macromolecular chemical technology. Each hollow fibre membrane has a macaroni-shaped cross section and has millions of pores on the sidewall. It can remove particles as small as 0.1 micrometer from tap water.
