The Sprite High Output Shower Filter installs in less than five minutes. Just remove your shower head, screw on the filter, then screw your shower head to the other end of the filter.
Cartridge change does not require removing the filter from the shower arm. Just unscrew it in the middle, replace the cartridge, and screw it back together.
The only recommended maintenance is reversing the filter cartridge once a month. Many users, however, do not reverse the cartridge and get good results. Reversing the cartridge with improve flow and add to the life of the cartridge.
