How do you test a filtration mask?

Test for good filtration and fit

But a much simpler method is the candle test, popularised by US science educator Bill Nye. If you can blow out a candle while wearing your mask, that's a fail. It means your mask doesn't adequately stop the flow of air. If you can blow air out, air can also leak inward just as easily.

How can filter efficiency be improved?

To increase air-filter efficiency, select a filter with a lower pressure drop. Filters with lower pressure drops have less resistance, which increases airflow and helps your air conditioner operate more efficiently. Dust-holding capacity is closely related to pressure drop.

What is particle filtration efficiency?

Particle Filtration Efficiency (PFE) is aimed to determine the up-or downstream efficiency of filter materials and devices to retain submicron level particles. Also referred to as the Latex Particle Challenge, this test is performed on materials allowing one cubic meter per minute (1 cfm) flow
