Water Filtration Technology Explained

Every water filter is built around one or more of eight core technologies — activated carbon, reverse osmosis, UV, ion exchange, ultrafiltration, ceramic, distillation, or KDF media. Each one removes different contaminants and misses others. The technology that's right for you depends entirely on what's in your water, not on price or marketing claims. These guides explain the science behind each approach and which contaminants each technology is and isn't certified to remove.
