What Is Purified Water?
Depending on who you talk to, purified water is considered one of two things:
Water that has been through a process (such as activated carbon filtration, distillation, deionization, reverse osmosis, or ion exchange) to remove any impurities (such as heavy metals, pollutants, and solids), or...
Water that is free from specific impurities, including bacteria and viruses!
We prefer the second definition because it matches what the U.S. EPA recommends.
So purified water (or pure water) is water that is free from impurities, including bacteria and viruses!
