All performance claims and pricing were taken from the manufacturer's literature and certified claims.
Many models were considered and not included in this comparison because of undocumented or exaggerated performance claims. Some brands made exaggerated claims in their literature and on company web sites that did not match their "certified claims". Only performance claims that have been certified by NSF, UL or the CA. Dept. Of Health were included in our comparisons.
The water treatment industry is extremely regulated. Companies that market undocumented products, or make uncertified claims are heavily restricted as to how and where they can sell their products. Beware of products that offer different Performance Claims in different states. CA, WI, IA, and several other states, prohibit uncertified claims.
