Avesa Water Filter Quality
Your Avesa Wellness Water System comes with five filters, four of which require periodic replacement to keep the water flowing at its crystalline best. The Crystal-Boost Technology filter does not require changing.
Note that there are two different qualities of carbon filters, including antibacterial silver. ORG values are listed.
This chart below does not show the sediment filter. Originally it was not going to be included, but the extra filtration was needed due to the poor quality of municipal water providers. So this is actually a five filter system.

The largest single section in the of the "EPA Regulated Water Contaminants" published in Water Technology magazine, is the section on Organics (including VOCs, or "Volatile Organics"). In this category the EPA lists 32 very nasty chemical contaminants - many with familiar names like benzene, 1,1 dichlorethylene, carbon tetrachloride, dioxin, styrene, toluene, chloroform, and vinyl chloride. To give an idea of the extensiveness of this list, a single one of the 32 items is "Total Trihalomethanes", a category made up of still uncounted chemicals, assumed to number in the thousands, that are formed when water containing organic matter (i. e., virtually all water) is treated with chlorine. The maximum allowable level for trihalomethanes, which are suspected cancer causers and are present in virtually all chlorinated tap water, is only 1/10 of one part per million. For the Organics category, the primary treatment in all cases and the only recommended treatment in most cases, is activated carbon.
The EPA's Pesticides category lists 14 familiar poisons such as Aldicarb, Chlordane, Heptachlor, and Lindane. In all 14 cases, activated carbon is the only recommended treatment. Of the 12 Herbicides listed (2,4-D, Atrazine, etc.), activated carbon is the only treatment recommended.
For Organics, Pesticides, and Herbicides, the standard treatment, and in most cases the only treatment recommended, is activated carbon.
