BOCA RATON, FL (08/09/06) -- Pure H2O Bio-Technologies, Inc. (Pink Sheets:PHBT) announced today that it filed on July 25, 2006, a Non-Provisional Patent with the United States Patent and Trademark Office, Washington D.C. for Tetrasilver-tetraoxide (TTO) as a Disinfectant Agent for Cryptosporidium. This patent is a follow-up for the Provisional Patent filed on July 28, 2005.

Joseph P. Doxey, President of Pure H20 Bio-Technologies, Inc., said, "The claims, which PHBT accomplished by extensive research and testing included in the patent application, bring the company near to the status, which will give the disinfection system NSF certification."

Pure H2O Bio-Technologies, Inc. developed an improved scientific protocol for this product and engaged Clancy Environmental Consultants, Inc. (CEC) St. Albans, Vermont to perform disinfection studies utilizing TTO as an alternate disinfection process for potable/drinking water.

TTO is an ideal candidate for disinfection of deadly waterborne pathogens such as Cryptosporidium and other protozoans such as Giardia lamblia, whose cysts or oocysts are chlorine-resistant. This current application is a new development in the use of this product for drinking water disinfection within a contained system developed by Pure H2O Bio-Technologies, Inc.

The United States Environmental Protection Agency has stated 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.

It should be noted that very few laboratories in the world have the capability to test for efficacy against Cryptosporidium oocysts. For this reason, PHBT chose Clancy Environmental Consultants, Inc. who is nationally/internationally recognized for their expertise in performing these tests and advising commercial and federal clients. PHBT is confident that claims described in its patents for both microbiology and engineering fields will be verified, thereby placing it in an optimum position to claim a significant market share.
