We receive lots of questions from our customers regarding the amount of ozone needed to remove odor from an object or place. While the details of the odor in your space or object make a difference in the amount of ozone needed, it is generally more successful to use a lower concentration of ozone for a longer duration than a higher concentration for a short amount of time.
For example, I had a canvas tool bag sitting in my garage that a cat had unfortunately urinated on. When I discovered the odor embedded in the tool bag from the urine, I decided to use ozone to eliminate the odor. I began by placing the bag into a plain cardboard box and ran a 40-gram ozone generator at approximately 8 percent and ran the line out. I ran the test for approximately 15 minutes.
I ran another test with the same bag in the same box. I used an ozone generator capable of .25 grams of ozone. This test was run overnight. The results were very interesting. The first test made my whole bag smell like ozone and the urine odor returned shortly after. The second test, on the other hand, was much more successful in eliminating the odor instead of just covering it up.
This is a great example of how it is not always the best solution to use high concentrations of ozone but instead give the ozone the adequate amount of time to penetrate and eliminate the odor.
