"Ozone owes its fame to its remarkable power of killing bacteria. That is why the world should look upon ozone as a gift to mankind. No matter how much bacteria there may be, direct application of ozone by Nature, or direct application of ozone reproduced in controlled environment will destroy any kind of bacteria, in any amount."

"Experiments with cholera and typhus bacteria are rather awkward to be carried out in a private plant, handling, say a million gallons of water per day, and the firm Siemens and Halske were very fortunate to find the Prussian State officials willing and ready to test the matter. Dr. Ohlmueller and Dr. Prall published results of their finding regarding the action of Ozone on bacteria. The experimental series covered the effect of Ozone on pure water infected with 16,000 cholera, at another time with 30,000 to 40,000 typhus, and another time with 20,000 to 40,000 coli bacteria. The result was absolute sterility after treatment. The next step was to see the result on infected ordinary river water carrying over 4,000 bacteria. After treatment with Ozone, some 5 or 6 were left over and those were harmless."

"Ozone in the air in minute quantity of only 1 part per million retards the growth of bacteria and molds."

"Ozone is a powerful germicidal. Its high germicidal activity is doubtless due to its oxidizing power."
- E. K. Rideal, Ph.D.

"Ozone generators have been installed in many homes, and that super-oxygen is particularly destructive to all microbes and at the same time it makes inert the dangerous dust with its bacteria laden tenants."

"One part Ozone in 2 million p. solution renders the virus polyomelitis inactive within 2 minutes compared with the double amount of chlorine using 3 hours."
