Are air purifiers effective in preventing asthma attacks?

1 doctor agrees

In brief: Yes

I must qualify this answer. If the purifier has hepa filters with a very fine filtration rating, most allergens like pollen, dander, etc may be removed and a good result may be seen.
Make sure to clean the filter outside so any trapped dander, plooen, etc can be away from the asthmatic and nnot dumped back into the home environment.

In brief: Yes

In patients that asthma symptoms are worsened by dust and environmental allergens, air purifiers seem to work very well.
