The 7-stage home reverse osmosis system by Home Master features an upright design with modular filters for easy access and replacement. While most RO systems require filters alone to be replaced periodically, the Home Master system replaces the entire module. Modules are required to be replaced periodically anyway, so the Home Master system allows you to do so with the filter. With larger fittings and tubing, along with a non-electric water pump, the Home Master system has a much faster flow and is much more water efficient than most RO systems.
