Each cartridge uses our intelligent filtration system, combining Certified KDF-55, Coconut Activated Carbon, and Calcium Sulfite - selected specifically for shower water to reduce chlorine, heavy metals, and everyday impurities.

With a HYDRA subscription, your replacement filter arrives automatically every 90 days, so your water — and your routine — stays effortlessly consistent.

Specs

Our internal KDF-55 and premium Coconut Carbon filters are the longest lasting filtration system, giving you a skin-loving shower for up to 3-4 months.
