Objective: To evaluate the clinical efficacy of a new air cleaning device (LG Electronics, Korea) equipped with electrostatic precipitator (EP) and photocatalytic plasma filter (PCP) in 24 respiratory allergic subjects. Material and method: Air cleaning conditioner and air cleaner were placed in living room and bedroom. Both EP and PCP (EP/PCP) filters were used for the first 4 weeks and for another 4 weeks, PCP without EP filter (PCP) was used. We measured symptom scores of asthma and rhinitis, peak expiratory flow rate (PEFR), serum eosinophil cataionic prote in? in ECP, Dermatophagoides farinae (DF) specific IgE and IgG in sera, concentrations of major allergens of DF in floor dust of living room, bedroom and in airborne dust. Results: Both asthma and rhinitis symptom scores were significantly improved not only with EP/PCP filters but also with PCP filter. The morning PEFR was significantly improved with EP/PCP filters, but not with PCP filter. Frequency of salbutamol inhalation by air cleaner with EP/PCP filter tended to de crease(p0.051), with no significant difference in serum ECP concentration. DF specific IgE significantly decreased at the 8th week with no differences in specific IgG. However, the mean Der f I levels in floor dust of bedroom (1, 128 vs. 374 ng/gm dust, p<0.01) and living room (1,516 vs 812 ng/gm dust, p<0.01) decreased, Der f1 in airborne dust measured only in 8 out of 22 subjects, and they decreased significantly with the trial of EP/PCP filter (172.2 pg/4.5m vs. 62.1 pg/4.5m, p<0.01). Conclusion: These results suggest that the EP/PCP air cleaner may be an effective tool for environmental control in respiratory allergic subjects.
