The water you shower in is typically treated with chlorine and other chemicals by your municipal water supply to keep your water safe, but this can actually be harmful when absorbed in large amounts. These chemicals can damage hair, skin, nails, and when inhaled through steam in a hot shower can even irritate your throat and lungs. For sensitive, dry, or damaged skin and hair, the iSpring SF Series Shower Filters (SF1S, SF2S, SF3S) provide the solution you need. Featuring a scientifically formulated process of 12 different filtration media in 15 stages, iSpring SF series shower filters significantly remove sediment and reduce chlorine, pesticides, heavy metals, and chemicals coming into the shower. Compatible with every standard 1/2 in. shower and all types of showerheads (fixed, handheld, rain), iSpring shower filters purify shower water to give you smoother, softer, and shinier skin and hair, making showers a pleasant experience and a health journey for you and your loved ones.
