OdorStop, the leader in the ozone industry, has developed a revolutionary new product, the OS4500UV2. It is the first and only combination ozone generator and UV air cleaner and can be used to eliminate odors at their source at a high rate in occupied spaces, even with the ozone off. To accomplish this innovation, we took our top rated UV model and added an “off” option to the variable ozone output, an extra 254 NM UV-C bulb, and a charcoal filter - features never before used on an ozone generator. It is truly a breakthrough in ozone technology and the only professional grade ozone generator that can be used in occupied spaces. The OS4500UV2’s patent pending design and technology guarantees it is the most versatile ozone generator available. It is lightweight, has variable ozone output, a timer with a “hold” option, and the 4 ozone plates can be cleaned without taking the unit apart. In addition, the ozone plates are pre-installed at our factory so there is no assembly required. With an industry leading 300CFM fan, it is perfect for eliminating odors and deodorizing large areas such as hotel suites, offices, homes, basements, and more.
