Is this the best type of drinking water filter for my water?

If the water to be filtered is municipally-treated city water low in minerals, then less expensive carbon block filtration systems may be sufficient. If the water is very high in minerals, then a reverse osmosis system that removes minerals, salts and chemicals may be desired. In many cases people generally prefer water treated by reverse osmosis, since it provides purified, "bottled-quality" water, instead of just merely removing chlorine tastes like many filters.
