OdorStop units have been imitated, even to the point of others copying our exact model numbers. In addition, most ozone manufacturers misrepresent the ozone output of their units knowing that customers do not have the equipment necessary to measure the output.

We accurately report the ozone output and are committed to research, development, and technological advances that leave others trying to follow, but never able to catch up. We continue to set the standard in the industry with a 5 year warranty and a 30 day money back guarantee. The OdorStop OS3500 is the perfect choice for anyone looking for the best ozone generator available.

To ensure you are purchasing GENUINE OdorStop products, and not an imitation, please look for the trademarked OdorStop name and logo.
