Pure H20 Bio-Technologies, Inc. Announces New Filing U.S. Provisional Patent Application For Tetrasilvertetraoxide as Disinfectant Agent for Cryptosporidium
11/7/05

BOCA RATON, Fla., Nov 07, 2005 (BUSINESS WIRE) --
Pure H20 Bio-Technologies, Inc. (Pink Sheets:PHBT) announced today it filed a new Provisional Patent Application with the United States Patent and Trademark Office, Washington, D.C. for Tetrasilvertetraoxide as a Disinfectant Agent for Cryptosporidium.

Pure H20 Bio-Technologies, Inc. engaged Clancy Environmental Consultants, Inc., (CEC) St. Albans, Vermont to perform disinfection studies utilizing TTO as an alternate disinfection technology. Tests on TTO were performed by CEC with progressive reports dated 1204, 3-31-05 and, 7-1-05. The studies concluded TTO, used as a disinfectant, is a superior product that out performs halogens in the process of killing Cryptosporidium parvum oocysts.

Joseph P. Doxey, President of Pure H20 Bio-Technologies, Inc. stated, "Given the fact that the Pure H2O Bio-Technologies water purifier system contains the disinfectant within the system and only releases disinfectant-free potable drinking water, TTO became an excellent candidate for disinfection of Cryptosporidium.

PHBT followed a strict and meticulous protocol to qualify for NSF certification. It achieved new successes in the studies utilizing TTO, accumulated extensive raw data in disinfection technology and filed two patents with the U.S. Patent and Trademark Office in Washington D.C., with one patent currently under review and the other patent-pending recently submitted. The claims PHBT accomplished by its extensive research and testing bring the company one step closer to the status required for NSF certification. Attaining these claims that PHBT described in its patents for both the engineering and microbiology fields of the disinfection delivery system places PHBT in an optimum position to increase its market share.

TTO Background: Tetrasilvertetraoxide (TTO) is considered to be a viable candidate for killing Cryptosporidium a deadly waterborne pathogen. Silver compounds have for many centuries, been used to purify water for drinking and for the prevention and treatment of pathogenic microbes. It has been tested successfully against numerous bacterial and algal strains. The scientific findings of the United States Environmental Protection Agency included a statement that adequate product chemistry, efficacy (killing of EPA specified microbial species), environmental fate, toxicology and ecological effects data have been reviewed showing that human exposure from the purposed use is minimal.

The Company

PHBT is a publicly held company specializing in the manufacturing, design and sale of its unique residential, commercial and hospital point-of-use potable water disinfection systems. These systems are specifically designed to work effectively against water-borne pathogens and remove heavy metals and objectionable biomass.
