Here presented in no-fuss 'Black', Hello Klean's Rain Shower Filter combines the benefits of filtered shower water with a spa-like rain shower head for a purified showering ritual that's nothing short of indulgent. From dry skin to unbalanced scalp, the shower filter is designed to counteract the effects of hard water. Its hero ingredient is calcium sulphite which acts to off-set about 90% of chlorine. Added to this is activated carbon to trap contaminants and eliminate odours in your shower. For additional plus points, the filter is studded with ceramic beads that enhance filtration altogether. What we love most? It's a refillable style and made with only the bare minimum amount of plastic needed.
