Use of laminar air flow portable filter in asthmatic children.

A new, portable laminar air-flow filter (Enviracaire) was tested on 13 asthmatic children, using a double-blind single crossover study. There was a statistical improvement in symptom scores during filter use; however, peak flows did not improve significantly. The authors feel this method of avoiding indoor airborne irritants is useful and warrants further study.
