Selective Filtration™
Our proprietary Selective Filtration™ technology removes 99.9% of contaminants while leaving in all essential minerals. Reverse Osmosis (RO) filters also remove 99.9% of contaminants, however, RO also remove ALL the minerals found in tap water – including minerals your body needs. RO systems can waste thousands of gallons of water annually while flushing contaminants down the drain.

Preventing Sediment Buildup
If your water supply contains elevated levels of sediment, a dual-stage Sediment Removal Filter System is recommended to prevent decreased filter life due to particulate buildup within the filter. Rust from old plumbing, upstream construction contributing to excess sediment finding its way into your water supply, and water supplies with high levels of sand and contaminants can all result in water conditions not suitable for a single-stage filter system.
