shower filters with 25 levels of filtration, replaceable filter cartridges to prevent limescale and remove chlorine and heavy metals

True 25-Stage Filtration: Our 25-stage filter cartridge doubles the most effective filtration media (KDF 55, calcium sulfite, resin) compared to other 20-stage filters on the market, while also adding 5 new filtration media (zeolite, selenium-enriched ball, tourmaline, porous ceramic ball, small molecule ball) for more efficient and superior filtration in both hot and cold water, without clogging or changes in water pressure. Purifies and softens water – effectively reduces chlorine, heavy metals, impurities, and unpleasant odors; adjusts the calcium and magnesium ratio to soften water; inhibits limescale buildup; balances the water's pH; and infuses beneficial minerals to improve dry skin, dry hair, and more. Long-lasting: Each shower filter cartridge can last approximately 3 to 6 months or 12,000 gallons of water (depending on your local water quality and frequency of use). The worse the local water quality and the more frequently you use it, the more often you will need to change it. Universal filter replacement: These 25-step replacement filter cartridges are a common size, so they can fit any shower filter housing of a similar design. Easy installation: No tools are required; simply open the shower water filter housing, remove the old filter, and replace it with a new one.
