The world currently faces a global epidemic, and as we try to navigate the circumstances surrounding the spread of COVID-19, it is prudent to consider indoor air quality. The most effective means of reducing the transmission of this virus continues to be through respiratory etiquette, handwashing, disinfecting surfaces, and social distancing. However, the following engineering measures can be taken to maintain a healthy work environment, and may reduce virus transfer.
- Simple things that can be done right away:
- Increasing ventilation air-flow to purge virus and other contaminants from the building
- Operating systems for a longer period of time, preferably 24/7, instead of just during the day time
- Things that require some additional effort, but are an investment in long-term health:
- Increasing air filtration to the MERV-13 or better
- Installing UV or ionization filters to help kill viruses in the air flow
These recommendations may help improve the health of both people and buildings, and are consistent with the OSHA Guidance on Preparing Workplaces for COVID-19 and the CDC Interim Guidance for Employers and Businesses.
