Irritants that are embedded into furniture or flooring are also not captured by them.

Additionally, the efficiency of air cleansers in real-world situations likely will not simulate those of regulated conditions in a laboratory (what those “99% efficiency” claims are describing!). The location, setup, circulation rate, and how long it is running for will all differ, as will the conditions in the area.

The industry requirement for such is that the system needs to have the ability to get rid of at least 99.97% of particulates determining 0.3 micron size in a laboratory setting. Keep in mind, it is very important to keep in mind that in reality settings, the real effectiveness of these devices would be far less as new contaminants are continuously emerging.
