Abstract
The present invention relates to a mineral filtering apparatus in which the raw water is passed through a plurality of filtering processes, such as automatically filtrating without pressure, multiply filtering, ions exchange, sterilization, deodorizing, and releasing mineral substance. The filtering apparatus generally comprises a cover, an inlet water box, a first filtering unit, a filtering box, a second filtering unit, a storing reservoir, a mineral substance barrel that is disposed within the reservoir, an outlet filtering core that is disposed within the reservoir, a spout, a bottom bracket, and a water pan. The storing reservoir is provided with a mineral stone barrel with which the water soluble mineral substance is released. When the raw water flows from top to bottom, it can be treated with filtrating, deodorizing, ions exchange, sterilizing, magnetizing processes such that the treated water is clean and suitable for direct drinking. The treated water contains plentiful mineral substances that are nutritious to human beings.
