Due to concerns about coronaviruses this fall, the UW class, which is usually concerned with air pollution and emissions, has begun to focus on another aerial health hazard, the coronavirus aerosol.
Air pollution expert Julian MarshallUW, a professor of civil engineering and environmental engineering, leads the class in building and testing low cost DIY air purifiers. The MERV filter used in the design can remove virus particles from the air in addition to common contaminants and can be used to reduce the risk of COVID-19 infection.
These types of homemade air purifiers have already succeeded in removing particles from wildfire smoke from the air.
As part of the class project, students design different configurations of purification equipment and test how effective they are. First, the students created a “one fan, one filter” device. Next, we built a larger device with 2-5 filters in the shape of a triangle or a 3D box.Students do their own test A device to see if it’s better for a fan to push or pull air through a filter, how loud the purifier is, and how effective it is in removing particles from the air.
