Objective witnesses such as cats and dogs have proven the benefits of HRCM filtered water. If an animal is given different plates of water to make a choice with tap, any bottled and HRCM filtered water it will choose the last. The cups may be changed: for example, pour HRCM filtered water in the cup where the bottled water was, the result will not change: having a choice, an animal will drink HRCM filtered water.

The necessary to change aquarium water once a week is common knowledge. For that it is necessary to settle tap water for several days in a separate container. It was noticed that aquarium fish (both small and big) felt perfectly at home in HRCM filtered water (there was no need to settle it first). Water also can be changed less often.
