OdorStop, the leader in the ozone industry, is pleased to offer the OS4500UV. 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 OS3500UV, which has become the standard in the ozone industry, but it has a larger blower and 4 ozone plates instead of 3. It will eliminate even the most severe odors caused by mold, mildew, tobacco, fire and smoke, water and flood damage, animals, and more.

The OS4500UV has variable ozone output, a 12 hour timer with a constant on (hold) option, and is equipped with a UV light for additional sanitizing power. The UV function allows bacteria to be killed at a very high rate even when the ozone is on low. The ozone plates can also be cleaned easily without having to take the unit apart.

We continue to set the standard in the industry with a 5 year warranty and a 30 day money back guarantee.

About UV
OdorStop offers the OS4500UV model with a UV function which has the added benefit of ultraviolet filtration of bacteria and viruses. The advantage of this unit is that it can be run continuously with the ozone on low and still kill bacteria at a high rate. Examples of usage for UV include restaurant kitchens, bathrooms, food processing facilities, warehousing, etc.

Ultraviolet light is simply one form of energy coming from the sun. UV is as old as the earth itself and actually purifies outdoor air. UV offers benefits from special lighting for science and industry to disinfecting characteristics.

Ultraviolet lamps are in disinfection technology to target and destroy disease-causing bacteria, viruses and microorganisms. UV light has been proven for decades to effectively disinfect air, surfaces and water.

In some instances consumers require filtration of bacteria and viruses in addition to odor elimination. This is why OdorStop offers models with a UV function. Our UV models come with a high quality bulb which should be changed about every 2 years depending on usage.
