Do air purifiers help cure asthma?

In brief: No

But they may help remove allergen particles from the air that may trigger the hypersensitivity reaction that is the basis of asthma.

In brief: Filters / purifiers

Air filters capture particles; some purifiers treat the air chemically.
How the air changes depends on which you use. In order for a filter to have a significant effect on an allergy, it needs to filter the volume of air in the room at least 10 times per hour and be highly efficient, e.g. 99.74%. They help most for pet dander: light particles that stay airborne much longer than dust mite particles.

Air filters can help control allergen exposure and reduce asthma attacks and severity but they can't cure asthma.
