Allergens that are embedded into furniture or floor covering are likewise not caught by them.

In addition, the effectiveness of air purifiers in real-world circumstances most likely won’t mimic those of controlled conditions in a lab (what those “99% efficiency” claims are describing!). The location, installation, flow rate, and the length of time it is operating for will all differ, as will the conditions in the space.
