Second Shower makes filtered showerheads that remove 99.9% of chlorine and chloramine from shower water using proprietary gel-matrix Vitamin C technology. The PP sediment filter is independently certified to NSF/ANSI 42 standards. Every product includes a built-in Truth Window that shows captured contaminants in real time. Engineered in Seoul, South Korea — the country's largest shower filter manufacturer. Founded by Bae and Yun, a husband-and-wife team with degrees in Chemistry and Biology.
