This project is based around the not-so-obvious premise that commonly available household materials are at least modestly effective at filtering particulates from the air.  A big part of what motivated me to do this project was stumbling across papers like these, which show fairly promising results using ad-hoc materials like cotton shirt fabric or tea towels.
