Domestic and foreign water purifier suppliers are expanding in China, where households are feeling the pain of clean water shortages.

Companies such as United Kingdom-based Unilever, Beijing Origin Water Technology Co and United States-based Amway have developed their own water purifiers.

Unilever, the global consumer goods giant, plans to sell its water purifier, called Pureit, in China starting on July 1. It has already begun trial sales in Nanjing and will expand into Suzhou, Wuxi, Changzhou in Jiangsu province and Shanghai this year.
