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

In addition, the efficiency of air purifiers in real-world scenarios likely will not mimic those of controlled conditions in a laboratory (what those “99% efficiency” claims are referring to!).

True HEPA. Real HEPA filters are effective at eliminating ultra fine particles (think: dust, dander, pollen, mold and other common irritants in the house). The industry requirement for such is that the system should have the ability to get rid of at least 99.97% of particulates measuring 0.3 micron size in a lab setting. Remember, it is important to note that in real life settings, the real effectiveness of these gadgets would be far less as new pollutants are continuously emerging.
