Irritants that are embedded into furnishings or floor covering are also not caught by them.

Furthermore, the effectiveness of air cleansers in real-world situations likely will not mimic those of regulated conditions in a laboratory (what those “99% efficiency” claims are referring to!).

The industry standard for such is that the unit must have the ability to eliminate at least 99.97% of particulates determining 0.3 micron size in a laboratory setting. Keep in mind, it is very important to note that in real life settings, the real effectiveness of these gadgets would be far less as brand-new contaminants are continuously emerging.
