While selectively leaving minerals intact, our filters remove the 19 unwanted substances specified by Japanese authorities.
The quality standards for tap water established by the Water Supply Act included 51 items that needs to be checked. However, the quality standards for bottled water included fewer items (i.e., 19 items). In addition, tap water can contain residual chlorine, bacteria, and other impurities. A Cleansui high-performance water purifier equipped with hollow-fiber membrane filters can effectively filter the 17 and 2 substances designated by the JIS S 3201 (Testing methods for household water purifiers) and Japan Water Purifier Association, respectively. It notably retains the useful and essential minerals inherently found in tap water.
Great cost-performance ratio and eco friendliness of Cleansui products compared to bottled water
Cleansui products have outstanding cost-performance ratio; a faucet-mounted purifier (one cartridge) can purify water equivalent to 450 2-liter plastic bottles of water. The use of tap water for drinking can reduce greenhouse gas emissions by 99.6% in five years. This is not achievable via single-use plastic bottled water products. Water purification via Cleansui products for drinking substantially reduces the burdens on both the household finances and our planet (earth).
Substantial after-sales support
Through our online store and Cleansui club, we provides substantial after-sales support such as periodic delivery of replacement cartridges and a 24 × 7 customer care service to resolve your queries. In addition, we provide services including delivery of mounting parts, on-site maintenance, online ordering of replacement cartridges, and notification of cartridge replacement time through e-mails or social media. Moreover, after-sales supports by e-mail and telephone are available. Our products have been designed for long-term use; therefore, our customers can use them without anxiety.
Sophisticated and user-friendly product design
Pitcher-type purifiers are typically stored in a refrigerator. Meanwhile, faucet-mounted water filter purifiers provide both unfiltered and filtered water via a switching mechanism. Built-in (under-sink) filtering systems facilitate a clean kitchen. Functions considering everyday usage are achieved via the sophisticated design of Cleansui water purifiers. Therefore, Cleansui water purifiers fit nicely to various lifestyles.
