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

Furthermore, the efficiency of air purifiers in real-world situations most likely will not simulate those of regulated conditions in a lab (what those “99% efficiency” claims are referring to!).

The market standard for such is that the unit should be able to eliminate a minimum of 99.97% of particulates measuring 0.3 micron size in a laboratory setting. Keep in mind, it is essential to note that in real life settings, the actual effectiveness of these gadgets would be far less as new pollutants are continuously emerging.
