The HTI Technology: Forward Osmosis
The Best Products
Developed in concert with the US Department of Defense, HTI filters have undergone extensive testing in independent laboratories and by the U.S. military. The nominal pore size of the HTI forward osmosis membrane is 3-5 angstroms. The size of bacteria range from 2,000 to over 500,000 angstroms. The smallest viruses are 50 to 1,000 angstroms. To put this in perspective, if HTI’s membrane pore is compared to the size of a dime then the smallest bacteria would be larger than a two-car garage.
The Best Technology
Conventional water filters fall short when confronted with a real war-time environment. Hand pumps use hydraulic pressure to move water across a membrane. If supply water is dirty, these systems often clog and fail. Chemical purification treatments can kill biological pathogens, but require precise dosages and exposure times and leave an unpleasant taste. In addition, chemical treatments do nothing to remove turbidity from your next drink. Conventional systems also fail against most chemical poisons and heavy metals .
The Best Science
HTI products employ a proprietary membrane filter that is hydrophilic (attracts water), allows water to pass through, yet blocks very small contaminants due to the tight construction of the membrane. Water is driven across the membrane, not by hydraulic pressure, but by osmotic pressure created by a standard sport drink powder on the clean side of the membrane.
