It is important to look at the source of the articles, many are sponsored by specific name brand filter wanting to sell you theirs. The minerals in the water such as Calcium and Magnesium sound healthy but they are in a crushed rock form and cannot be absorbed by the body. The body gets its nutrients from the foods that we eat such as plants that have digested the crushed rock minerals into a form that the body can now take in. If you are looking to get nutrients from your water it is best to start with a clean slate, Purified water, which is produced by reverse osmosis. Once the water is purified now you are in control to add your own vitamins, minerals, and electrolytes. Water, by definition, is hydrogen and oxygen and hydrates the body. A remineralizer filter can be added to put back minerals, however it is recommended to use your own, which gives you the control of what you are putting into your body.

Contaminants in water fall into one of four categories, physical, chemical, radiological, and biological.

Physical contaminants include soil, sediment, leaves, and other debris. Some physical contaminants may be from the water delivery system, such as rust in pipes. Chemical contaminants may be chemicals that produce naturally in nature or those developed and used by different companies.

Radiological contaminants are not so common. Biological contaminants are a form of bacteria and viruses. These contaminants are difficult to remove from water. In fact, in some cases, filtration alone may not be sufficient. Therefore, some types of water filters, are not designed to remove biological contaminants.

Common filter such as your refrigerator filter, pitcher type, and sink adaptor types are made with GAC (granular activated carbon) Carbon may address chlorine, lead, and other contaminants. The problem is carbon creates a feeding ground for bacteria. Costly maintenance changing filters is then required.
