OdorStop, the leader in the ozone industry, is pleased to offer the OS4500. It is the most powerful ozone generator in its class. It was designed to deodorize and sanitize very large spaces and is the only 4 plate ozone generator available. It has the same functions as our OS3500, which has become the standard in the ozone industry, but it has a larger blower and 4 ozone plates instead of 3.

The OS4500 has variable ozone output and a 12 hour timer with a constant on (hold) option.The ozone plates can also be cleaned easily without having to take the unit apart. It will eliminate even the most severe odors caused by mold, mildew, bacteria, viruses, tobacco, fire and smoke, water and flood damage, animals, and more.

BUYERS BEWARE! 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 OS4500 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.
