Introducing, Tyent's "Ultra Plus" filtration. These dual, oversized, multistage filters remove every day contaminants such as sediment, chlorine, chloramines and heavy metals, but that's just the beginning. A 3rd party laboratory has confirmed that Tyent's "Ultra Plus" filtration also eliminates hundreds of other poisonous toxins including herbicides, pesticides, pharmaceuticals and much more. The .01 micron filtration level found in our "Ultra Plus" filters is the same as what is used in kidney dialysis machines. "Ultra Plus" filtration ensures the purest, healthiest and safest water available today.
