The Airmaster T20 by Tuprotec has been set up at a cannabis cultivation facility in California to evaluate its odor removal effectiveness. Six fully functional units were placed above the crops in the facility. Over a period of about 20 days, from September 20 to October 11, engineers monitored the ambient ozone levels in the greenhouses while the Airmaster T20 system was in operation to determine if the system increased ozone levels in the working areas. Ozone measurements were taken using a model 49i ozone analyzer from Thermo Scientific, which is approved to meet US EPA standards.

During this time, the average ozone level in the greenhouses was 5 parts per billion (ppb). The highest level recorded in one hour was 23 ppb, when 3 out of the 6 units were running on medium. Other times, all six units were set to the highest level. These ozone levels are much lower than the state and federal limits for ozone. Even when the ozone levels were at their highest in the greenhouses, they were still lower than the ozone levels outside during the same period.
It was found that the Airmaster did not produce ozone at levels that could harm people or the cannabis plants in the greenhouse, as well as that, during the time of the experiment, the ozone levels inside the greenhouses were lower than the usual outside levels. As a result, using the Airmaster to control or reduce cannabis odors was not found to create issues related to ozone production and meets EPA standards.
