Subject:  OZONE - Indispensable in Schools


During the influenza epidemic in St. Louis, the most critical and 
advanced cases were transferred to an open air school, which made 
for high percentage of mortality.  In one particular ward, 
experiments were made with ozonized air on cases approaching or at 
the crises period of the diseases where patients were able to 
inhale at all, they WERE AT ONCE RELIEVED AND SUCCESSFULLY CARRIED 
OVER THE CRISIS.

Two schools were then used for an experiment, one with OZONIZED 
air and another with ordinary air.  Both schools contained 
approximately the same number of rooms.  The following cases of 
sickness were observed and tabulated: 

                    OZONIZED AIR  ORDINARY AIR
                       CASES         CASES

Tonsilitis              13             57
Sore Throat             24             60
Colds                   46             64
Headache                 9             66
Stomachache              0             25
Earache                  1             15
Toothache                0             20
Indigestion              0              9
Fever                    1             49
The Grippe               0              6
Pneumonia                0              4


Comparing the total days absent we find that in the school where 
OZONIZED air was used, the school children were absent, due to the 
foregoing cases of sickness, 475 school days, while in the school 
where ordinary air was circulated by means of the ventilating 
system, the school children were absent a total of 1,098 school 
days.

Thousands of lives would be saved every year if homes and schools 
were equipped with apparatus for the circulation of Ozone. 
Injected with the air of the building to the extent of one part of 
Ozone to one million parts of air, it effects approximately 100% 
purification.  In five years that Ozone has been used in the 
Public Schools of St. Louis, TUBERCULOSIS CASES HAVE BEEN REDUCED 
50%, ALSO OTHER DISEASES HAVE BEEN MATERIALLY REDUCED.
