The industry standard for such is that the unit must be able to remove at least 99.97% of particulates measuring 0.3 micron size in a laboratory setting. Remember, it is important to note that in real life settings, the actual effectiveness of these gadgets would be far less as brand-new pollutants are constantly emerging.
