Minimum Efficiency Reporting Values (MERV) at Dundee High School

High school students in Michigan construct 56 temporary MERV-13 filters to combat Covid-19

The air filters will be used in elementary and middle school classrooms until the school acquires permanent air quality units.

Students at Dundee High School in Dundee, Mich., have been constructing temporary air filters to help combat the spread of Covid 19. 

Students in the construction trades class have spent about 120 hours to assemble 56 units, reports The Monroe News

Filters are graded on their ability to capture particles using Minimum Efficiency Reporting Values (MERV). Most home units have a MERV-8 filter installed as the default; the students are using MERV-13 filters.

The filters on each unit will have to be replaced every 3-4 months. The units will be brought to elementary and middle school classrooms to help filter the air until the school is able to acquire permanent air quality units. 

According to the Environmental Protection Agency, although MERV-13 filters cannot completely protect people from Covid, they do have a greater capacity to capture smaller particles, including viruses.
