Cleansui, the trusted brand of water purification in Japan, removes contaminants while leaving minerals intact, delivering clean drinking water.

The original proprietary Clean Water filtration system ensures the high level of performance.

The unique and advanced filtration system uses a combination of a filtering net, non-woven fabric, ceramics, activated carbon as well as the proprietary hollow fiber membrane filters.

1Ceramic Filter*1

The special ceramic filter removes soluble lead, as well as other contaminants.(Insoluble lead is removed by the hollow fiber membrane.)

2Activated Carton Filter*1

Activated carbon filter reduces unpleasant odors, chlorine and mold (2-MIB). It also removes pesticides, herbicides, CAT, Volatile Organic Compounds (VOCs) such as total trihalomethanes (chloroform, bromodichloromethane, dibromochloromethane, bromoform). tetrachloroethylene, trichloroethylene, 1,1,1-trichloroethane and others.

3 Hollow fiber membrane filter

The core differentiator of Cleansui’s Clean Water filtration is the hollow fiber membrane filter made of ultra-fine polyethylene. The sidewalls of the membrane can remove minute particles (as small as 0.1 micrometer) in tap water; including bacteria, algea, fungi, micro-organisms, cysts, cyprosporidium, metal particles such as rust, lead and more.

Advanced technology

The microporous hollow fiber membrane is a sophisticated filter developed by Mitsubishi Rayon’s macromolecular chemical technology. Each hollow fibre membrane has a macaroni-shaped cross section with millions of pores on the sidewall. This technology allows for removal of minute particles as small as 0.1 micrometer from tap water.
