NSF-certified protection that works while you sleep – meet the filter that revolutionized under-sink maintenance

The Unseen Threat in Every Glass
Modern homeowners face a hydration paradox: while municipal water meets safety standards, residual chlorine, sediment particles, and microscopic cysts still lurk in every pour. Most solve this with bulky pitchers that clutter countertops or expensive whole-house systems requiring professional installation. The hidden cost? Compromised water quality during filter changes, mineral depletion from over-filtration, and the environmental toll of premature cartridge replacements.
Industry Insight: NSF testing reveals standard faucet filters miss 37% of chlorine byproducts, while Glacier Bay’s quarter-turn system achieves 99.6% reduction through its layered filtration matrix.
Engineering Breakdown: Three-Tier Filtration Science
1. Sediment Barrier
Melt-blown polypropylene fibers create a labyrinthine mesh capturing particles as small as 5 microns – that’s 20x finer than a human hair. This pre-filtration stage protects subsequent layers from clogging.
2. Activated Carbon Core
Coconut-shell derived carbon with increased surface area (1,000m²/g) chemically bonds with chlorine molecules while absorbing organic compounds responsible for unpleasant tastes and odors.
3. Microstructure Membrane
A pleated borosilicate glass fiber sheet provides mechanical cyst removal, trapping protozoa like cryptosporidium that resist chemical treatment.
