Bacterial Filtration Efficiency (BFE) Report

The BFE test is performed to determine the filtration efficiency of test articles by comparing the bacterial control counts upstream of the test article to the bacterial counts downstream.

InterMask BFE Report

Breathability Differential Pressure Report

The Delta P test is performed to determine the breathability of test articles by measuring the differential air pressure on either side of the test article using a manometer, at a constant flow rate.
