Texas A&M study looks into best materials for coronavirus masks
“We are conducting a study evaluating a wide range of household materials as resources for constructing DIY face masks,” said Professor Sarah D. Brooks, director of the school’s Center for Atmospheric Chemistry and the Environment (CACE).
The university is using aerosol counting and sizing equipment to produce airborne samples of non-biological particles, to test how well certain materials can filter them out.
The study tested the effectiveness of N95 respirators — which were found to be completely effective in stopping the non-biological surrogate particles — against the effectiveness of masks made from household articles.
N95 respirators were determined to be the best option, while coffee filters and bandanas were found to be the least effective choice.
