Pollen Capturing(Filtering) Efficiency

This is to test the fte ring parts in the masks to determine the performance of capturing (filtering) physically the alternative pollen particles. The altemative pollen particles in this test are about 30 μm that are about the same diameter as cedar pollen and shall be the natural-find particles which are reported non-allergicbased on the past allergic tests

Test Method Overview

Attach the conditioned sample on the test machine and let the particles fall evenly on one-side ofthe sample while a certain volume of the particles are sent into the machine at a constant speed Measure the volume of the particles which have passed through the sample against the volume of the provided particles and calculate the capturing performance(%)
