What contaminants does the Tier1 SF-WHR-140 shower filter reduce?The Tier1 SF-WHR-140 uses a specialized KDF-55 (Kinetic Degradation Fluxion) filtration media designed specifically for hot water applications. It effectively reduces chlorine, scale, sulfur odors, and water-soluble heavy metals that can dry out your skin and hair. Unlike carbon-based filters that lose effectiveness in hot water, the KDF media in the SF-WHR-140 performs reliably at shower temperatures, helping deliver softer, healthier water for bathing.

Replacement intervals may vary depending on your water quality, chlorine levels, and shower frequency. Replacing the cartridge on schedule ensures maximum chlorine reduction and consistent water flow through your Culligan WSH-C125 housing.
Is the Tier1 SF-WHR-140 NSF/ANSI certified?The Tier1 SF-WHR-140 is manufactured in an IAPMO-certified facility and is tested against NSF/ANSI Standard 177 for free chlorine reduction in shower filters.
