What’s inside and how it works

Independent lab data indicates effective reduction of impurities, chlorine, and scale buildup, supporting consistent system performance and water clarity.

• 3-layer filtration: particulates captured by PP cotton, taste and odor improved by carbon, mineral scale reduced by inhibitor
• Independent third-party lab data supports performance claims
