Abstract
Devices and methods for water purification are provided. An improved demister () for removing liquid or other particles from steam is disclosed. The demister can have adjustable outlets. In other embodiments, a demister apparatus is placed, at least partially, inside a boiler apparatus (). Additionally, a filter flow indicator () that provides an optical indication of the efficiency of a water filter is also provided. The filter flow indicator has a viewable side passage that connects the input and output sides of a filter unit. A weighted object, such as a ball (), can move up and down the side passage in response to the pressure differential in the filter system. The user can determine the status of the filter by viewing the location of the weighted object in the side passage. Additionally, a device and method of adding various minerals back to purified water in order to improve the flavor of the water is described. The device and method involve the use of a ground mineral mixture, typically chosen from minerals () that are common in natural springs. Pure water that runs through the mineral filter apparatus can take up some of the minerals, thus creating water that, although free from unhealthy contaminants, tastes like natural spring water.
