Are filtration products considered purifiers?
Technically, a purifier would be a system that provides “pure” water – hydrogen and oxygen with no other components. Pure water of this sort does not exist except in the controlled environment of a laboratory. Most references to “pure water” are in relation to the bacteria content and not the chemical contaminant concentrations. The EPA defines “pure” as water free from all types of bacteria and viruses. Each of these definitions would describe a system significantly different from a drinking water filter. Many filtration systems are designed to eliminate chlorine resistant parasites like cryptosporidium and giardia, but should not be sold as a means of treating water of unsafe bacteriological quality.
