The Sprite Shower Pure 7-Setting Filtered Shower Head has NSF certified performance in a plastic housing. Inside the housing is a replaceable 6 month filter cartridge (model SLC) which contains Sprite's exclusive blend of filtration media for a chlorine-free shower. All-In-One shower heads disguise their utility for an aesthetically pleasing, chlorine-free shower. Sprite's “All-In-One” filters combine a filter and shower head into one unit! They can be attached to any standard 1/2-inch NPT shower arm with no extra equipment. All-In-One units can alternately take the 9 month Royale Cartridge (model ARC). Sprite's plastic units have a 1 year manufacturer's with proof of purchase. Please refer to the manufacturer's website for complete information and registration.
