This replacement cartridge refreshes the Red Light Shower Filter attachment’s advanced 10-stage filtration system, helping ensure every rinse feels as luxurious as the first. The multi-stage filter with KDF-55 and activated carbon helps reduce chlorine, heavy metals, microplastics, and other unwanted impurities commonly found in shower water.

Powered by a thoughtful blend of filtration media and antioxidant-infused vitamin E spheres, the filter helps preserve skin's moisture barrier while minimizing exposure to contaminants that can contribute to dryness, dullness, and brittle strands.

Replacing the filter every 75 days—or every two to four months depending on household use—helps maintain optimal filtration performance and supports the full benefits of your HigherDOSE shower ritual.
