4 separate tests were run in the same room over a period of weeks due to occupancy at various times.
Allowable limits are standardized.
Bacteria must be less than 400 UFC/cm2.
Coliform (feces) must be less than 10 UFC/cm2
Test 1 > 4 hr. run at 8000 mgs/hr and 19 ppm. showing swab count before treatment and swab count after treatment using one generator.
Test 2 > about 2.5 weeks later was run for 2hrs (same concentration but half the time). Pre-treatment counts are much less than test 1 before ozone was ever introduced and tend to remain lower on all tests.
Test 3 > was written on 5 sheets of paper with before and after of one swabbed area on each sheet (unknown reason).
Test 4 > was done with smaller automobile machine at 2000 mgs/hr. and 17 ppm for a 4 hr duration
