There are some filtration companies out there that want you to believe that they can provide you equipment that will filter your tap water and make it comparable to our spring water. This is impossible and a false statement.
Filtration systems
range from charcoal filters and sediment filters that primarily take out chlorine, odor, and taste. Purification systems waste a lot of water, and do not remove all nitrates. Most systems are only about 90% effective. Filters require regular replacement and there is no way to know when that is without testing the water on a regular basis.
