By reducing chlorine, heavy metals, and other impurities, Oshin helps protect your skin barrier. The micro–nano bubbles cleanse deeply yet gently, supporting hydration and calmness from the very first touch.

Oshin fits most standard faucets with a round spout and removable aerator. It’s not compatible with pull-out, pull-down, or irregularly shaped faucets.

The filter lasts about 3 months with regular use. The built-in display will remind you when it’s time for a replacement.

Oshin uses an Ahlstrom carbon fiber filter—engineered for high performance and sustainability—to capture impurities without stripping beneficial minerals.
