Evaluation of air purification technology on eliminating cannabis chemicals and odor

The novel air purification technology, Nano-Confined Catalytic Oxidation (NCCO), has been proven to be effective at eliminating air pollutants. With the increasing legalization and decriminalization of medicinal and recreational cannabis and related products, respectively, in many countries and jurisdictions around the world, concerns have been raised about indoor air quality from smoking cannabis products, which produce gaseous pollutants and intense odor.

In this study, NCCO technology has been evaluated for its effectiveness in reducing key cannabis concentrations in polluted indoor air by direct measurements and odor intensity assessments by human volunteers. For the odor intensity measurements, 20 non-cannabis adults participated in the odor assessment. The results are remarkable and statistically significant. The reduction in Dronabinol, a pharmaceutical form of Tetrahydrocannabinol (THC), Cannabidiol (CBD), and Cannabinol, averages 93.4%, whereas that in airborne cannabis compounds with no air purification only averages 6.2%.

The technology also demonstrates statistically significant reductions in PM2.5, PM10, and total volatile organic compounds generated from cannabis smoke. The technology was able to restore high levels of harmful particulate matter to normal baseline levels. Furthermore, the odor assessment conducted by a group of 20 volunteers also confirmed statistically significant reductions in cannabis odor by 55.6% after 50 min of air purification.
