Abstract
An apparatus includes (i) a test chamber having an inlet and an outlet; (ii) an introduction system configured to introduce a test pollutant into the test chamber such that the test pollutant is entrained in air flowing from the inlet to the outlet; (iii) a support configured to retain the test article, wherein the support defines a passageway downstream of a location of the test article such that air flowing from the inlet to the outlet passes through the filter medium prior to entering the passageway; (iv) an air flow apparatus configured to draw air from within the test chamber through the passageway and the outlet; and (v) a respiratory conditions simulation system configured to simulate an aspect of respiration, an external environment simulation system configured to simulate an aspect of an external environment, or both the respiratory conditions simulation system and the external environment simulation system.
