Before the advent of the Internet, it wasn’t always easy for consumers to obtain information on water purifiers from manufacturers and distributors, and the only way to buy purifiers was through local dealers who offered only a very limited number of products. In contrast, there are now thousands of websites that not only provide a glut of information, but also sell directly to the consumer. For most products, simply type in the brand name of a purifier or generic descriptive terms ( for example, “drinking water filter ” ) in a search engine and you’ll find a multitude of websites that have detailed information and pictures, plus more models and options than can possibly be mentioned in this post.
