Refrigerator filters generally rely solely on carbon filtration. While activated carbon is very effective at removing a wide range of contaminants, the problem with this type of filters is that they contain a very small amount of activated carbon. Further, the time the water spends in contact with the carbon is too little to provide full absorption which makes the filter less effective.

In 1987 this exciting breakthrough technology for water purification was discovered. KDF media has been proven to be the best way to remove major contaminants from our water and shown to stay active longer than any other purification method. The result is better water than bottled water, at a fraction of the cost.

When KDF technology is combined with granular activated carbon, the KDF protects the carbon from rapid exhaustion with chlorine by handling the chlorine first, thus allowing the carbon to have a much longer effective life. KDF media with carbon has about 10 times the active life of carbon that is not protected like this.

KDF & carbon working together are proven effective against microorganisms, chlorine, heavy metals, (aluminum, arsenic, cadmium, iron, lead, mercury, etc.), hydrogen sulfide, nitrates, odor, poor taste, THM’s, PCB’s, dioxin, glyphosate and thousands of other organic chemicals and inorganic poisons, for an extended time, . . . at the minimal cost of approximately one cent per gallon.

An Ultrafilter serves as a barrier to separate harmful bacteria, viruses, and other contaminants from clean water. Water passes through a .03 micron membrane which only lets fresh and crisp water through the other side.
