In this double blind, placebo-controlled study we examined the value of using a device for ionizing the air in the immediate environment as a therapy for asthma bronchiale. Nineteen adult patients with stable, reversible asthma were randomised to blind treatment with either an active device or an inactive placebo-device. After four weeks treatment the patients were given the alternative device for another period of four weeks. We measured daily peak-flow, symptomscore, use of medicine and spirometry and found no differences between the two periods. Therapy with ionization of the environmental air in patients with bronchial asthma should not be recommended.
