Yes. The Viral Kill Model 450 uses UV‐C light to kill microbes and a catalyst to reduce odors and other gaseous contaminants. There is no ozone in the Viral Kill products. The Fresh Preservation products, Model 2400 and the Model 300, use UV bulbs that generate two different types of UV light: germicidal to inactivate microbes and ozone‐generating to eliminate ethylene and other gases. A catalyst removes all the ozone before exhausting clean air back into the storage facility. Removal of ethylene with the self‐contained ozone is critical to extend the shelf life of fruits and vegetables. The ozone also helps eliminate odors via an oxidation process.

No, unlike plasma generators, ozone generators, ROC generators, or ion generators, the Bluezone does not INJECT harmful contaminants into the space. In fact, the catalyst in all Bluezone models REMOVES harmful ozone from the ambient air.

The CDC recognizes the effectiveness of UV germicidal light in killing the coronavirus as well as molds and bacteria. This means air purification systems like Bluezone could be funded through federal relief measures.

UVC or ‘germicidal’ lamps have been used for decades in healthcare and other settings to kill bacteria (e.g., tuberculosis), or viruses in air (inside light‐tight air ducts), and for sterilization of drinking water. UVC radiation has been shown to inactivate the SARS‐Coronavirus.

Bluezone Model 450 has been tested at a third‐party virus testing lab demonstrating that Bluezone eliminated 99.9995% of the virus broadly used as the surrogate for the SARS‐Cov‐2 coronavirus.
Bluezone Products, Inc. the company that developed and manufactures the Model 450 has had extensive studies conducted by engineering and public health companies to define the right number of Bluezone units needed to reduce risk in various indoor settings. Following the guidelines provided for the number of units needed in restaurants is expected to provide a level of risk reduction that is the same as having customers wear cloth masks.
