HigherDose Red Light Shower Filter Review (2026): Filter Needed

HigherDose has released a $600 red light shower filter combining a 10-stage water filtration system with red and near-infrared light therapy, claiming benefits for skin, scalp, circulation, and mood. After two months of testing, the reviewer found modest mood improvements and confirmed some filtration effectiveness, but noted the high price compared to top-pick shower filters and insufficient documentation for some of HigherDose's bolder filtration claims.
