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

Additionally, the effectiveness of air purifiers in real-world circumstances likely will not mimic those of regulated conditions in a laboratory (what those “99% efficiency” claims are describing!).

The industry requirement for such is that the system needs to be able to get rid of a minimum of 99.97% of particulates measuring 0.3 micron size in a lab setting. Keep in mind, it is necessary to keep in mind that in reality settings, the actual effectiveness of these devices would be far less as brand-new pollutants are continuously emerging.
