Box fan air filter efficiency experiment explanation | Stephen Clark

It's been 6 weeks and our box fan air filter is filthy! It's time to change the filters and we wanted to show you how much dust we've collected from the air. Now, we've reversed the airflow direction of the fan and filters to do a comparison and see which method collected more dust before losing efficiency! | Stephen Clark
