*What does this data mean*
Filtration Efficiency: The ability to filter out ~64nm NaCl particles using my test setup. Higher number is better
Time to Breathe: This is a kinda of crappy measurement that I use to estimate breathability. I time how long it takes me to breathe in while holding 0.25in H20 pressure drop. Longer time means the mask is hard to breathe in.
Pressure Drop: Using my Time to Breathe data I have estimated NIOSH 85LPM pressure drop. This is a measurement of resistance to airflow, so a lower number is better.
