Berkey Water Filtering Performance
All Berkey Water Filter systems are classified as water purifiers. In order to meet purification standards, a water filter must be able to remove specified contaminants to a predetermined level, known as a "standard". This purification standard is the highest level of water contamination removal that a water filter can obtain and very few manufacturers are able to make the purification claim without the use of harsh chemicals like iodine or chlorine. Berkey does not use chemicals. Instead, we rely on simple time-tested micro-filtration and a unique ionic absorption technology to purify the water.
