Controlled trial of an electrostatic precipitator in childhood asthma.
A cross-over trial was conducted on 10 children with moderate to severe asthma, who had positive skin tests to Dermatophagoides pteronyssinus and nocturnal wheeze. An electrostatic precipitator was used during the night to remove airborne particles from the bedroom. During use of the precipitator peak expiratory flow rates were no better than in a control period.
