Water filtration removes dirt and sediment to clarify water and, in some cases, may also remove cysts. Few filters remove bacteria. None remove viruses without requiring extremely sophisticated (and therefore costly) membranes and high water pressure. In short, clear water doesn’t mean it’s pure, and if it’s not pure, it’s not safe to drink. In India, 86 percent of the water supply is improved, but much of the water is not safe.
 
Water treatment covers a wide range of techniques that make water more acceptable for a desired end use. A water treatment may or may not include water purification.
 
Water purification removes contaminants and germs from untreated water to produce drinking water that is pure enough for human consumption. HaloPure is an exceptional purification technology that reliably, safely and effectively kills the bacteria and viruses left behind by conventional filters.
 
In the United States, the EPA regulates the word “purify” to mean six-log bacteria reduction (99.9999 percent), four-log virus reduction (99.99 percent) and three-log cyst reduction (99.9 percent), as tested under rigid conditions.
 
In other countries, the term “purify” has not been regulated to that extent. In India, the standard for “purified” water is continuous removal of three-log bacteria. HaloPure purification technology kills the germs, bacteria and viruses that can’t be seen. The level of purification (e.g., three-log to seven-log) can be adjusted by varying the amount of HaloPure beads used in the water purification product.
