Is there independent verification that KDF is effective?
In August, 1992, KDF was awarded the U.S. E. P. A.’s approval as a “pesticidal device”, which means it has the ability to kill algae, bacteria (including Pseudomonas florescens, Ybrio cholera, Legionella pneumophilia, and coliforms), fungus, mold, and many parasites and viruses found in drinking water supplies, through the natural process known as “electrochemical oxidation/reduction”. KDF has also been certified by independent water purification authorities to kill a target bacteria within the “less than 1 minute contact time” required to be effective in point-of-use water filters. Thus it is “bacteriacidal”, a much preferred classification to that of “bacteriostatic”, a term often used with filters impregnated with silver, which only slightly retards bacterial growth. NOTE: KDF is a relatively expensive substance. Our water purifiers have the substantial amount of KDF needed to do a thorough job. There are other brands, some with the same kind of housing as ours, that contain only a
