How It Works
How the filter Works

Hollow Fiber Membrane Filtration sounds complicated, but it’s actually not. It’s doing the same thing that a common kitchen strainer or coffee filter might do, but only at a microscopic level.

Now, obviously, there is more involved to Hollow Fiber Membrane Filtration than a simple "coffee filter," but at its most basic level, that's what's happening.

Using the same technology utilized in Kidney Dialysis, the tiny polysulfone hollow fiber micro-tubes trap all bacteria larger than 0.1 microns in diameter. Harmful bacteria and microorganisms which contribute to millions of deaths each year remain inside the filter casing and are removed by simply back flushing.

Our filters are tested by Pony Testing International and EPA certified laboratories in the U.S. according to the EPA testing method 600 standards.
