Our Technology

Cleansui is the trusted brand of water purifiers in Japan, and is now available in Australia and New Zealand. The remarkable purification system removed contaminants but leaves healthy minerals intact.

Cleansui's original proprietary filtration system ensures high level performance.The unique and advanced filtration system uses a combination of filtering net, non-woven fabric, ceramics, activated carbon with hollow fibre membrane filters.


1. Hollow fibre membrane: 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 particals such as rust, lead etc.


Advanced Technology

The microporous hollow fibre membrane is a sophisticated filter 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.

In addition to the hollow fibre membrane, water is filtered through non-woven fabric, ceramics, and anti-bacterial activated carbon filters in the purification process.


2. Ceramic: The special ceramic filter removes soluble lead, apart from other contaminants. (Insoluble lead is removed by the hollow fibre membrane filter).


3. 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.
