Ehdotuksen tiedot

This document stipulates a method that evaluates inactivation/removal effectiveness against airborne microorganisms in air cleaning devices, such as air filters set up in a heating, ventilation and air-conditioning (HVAC) system in commercial, institutional and office buildings, also air-purifying systems, or air sterilizers in these buildings. The airborne microorganism inactivation/removal effectiveness is based on an evaluation of the ability of the duct-mounted air-filtering devices to capture or inactivate bacteria, moulds or viruses with common particle sizes. By measuring the inactivation/removal effectiveness, the quality level of the product can be assessed. This method includes detailed requirements for the test rig, which simulates the nominal air flow rate of the devices. The method also covers data acquisition, analysis, and reporting of results.
