The industry standard for such is that the system should be able to eliminate a minimum of 99.97% of particulates measuring 0.3 micron diameter in a lab setting. Remember, it is necessary to keep in mind that in reality settings, the real efficacy of these gadgets would be far less as brand-new contaminants are continuously emerging.
