The Jolie Replacement Filter fits inside the neck of your Jolie Filtered Showerhead and needs to be replaced every 90 days. We made our filter best-in-class by focusing on the two most effective filter mediums for the shower: KDF-55 and Calcium Sulfite. This is the good stuff — built to remove more chlorine & heavy metals than any other filter on the market. Past the 90-day mark, the filter's efficacy will wane and it won't be doing its job. We shower everyday — treat your body right by ensuring your water is clean for a healthier, happier you. Our filter has been independently tested by third-party labs and far exceeds NSF-177 certifications for contaminant removal (including over 84% removal of chlorine through the entire lifespan of the filter, which far exceeds NSF-177 certifications of 50%) Far exceeds NSF-177 certifications Best-in-class at removing chlorine & heavy metals Ultrasonically welded to ensure quality Contains the two best filter media: KDF-55 & Calcium Sulfite
