Whole House Water Systems
Whole House (or point-of-entry) Water Systems process all the water used in your house (including for washing), and are usually installed right after your water meter. For systems or filters to treat only your drinking (or cooking) water, please see our wider Water Filters collection.
Two of these models, the Calmat and the Vulcan, only target specific factors such as calcium, lime scale, or rust which may be putting stress on your pipes, appliances, or hot water tank.
The principal ones are types of OPUS Water Purification Systems designed to remove a wide range of contaminants from regular municipally-treated chlorinated water: the OPUS - Whole House Water Purification Model 55 (which has two variants). Of course, Replacement Whole House Water System Filters are also available for these systems.
