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

Furthermore, the efficiency of air purifiers in real-world scenarios most likely will not mimic those of controlled conditions in a laboratory (what those “99% efficiency” claims are referring to!). The location, installation, flow rate, and for how long it is operating for will all differ, as will the conditions in the space.

Real 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 standard for such is that the system must be able to eliminate a minimum of 99.97% of particulates measuring 0.3 micron size in a lab setting. Keep in mind, it is essential to keep in mind that in real life settings, the actual efficacy of these gadgets would be far less as brand-new pollutants are continuously emerging. Note that there is no market standard for the terms “HEPA-like” or “HEPA-type,” and are primarily used as marketing tactics to get consumers to buy the product.
