Objectives: In order to probe into the curative effect of allergic rhinitis thought air filters, we test PM (including PM0.3, PM2.5 and PM10) before and after use it.
Methods: A total of 13 (33 ± 11 years old) clinically confirmed allergic rhinitis patients were selected to use the air filter for three months. Before and after the use of air filter (every month), indoor and outdoor PM contents of the subjects were tested. The change in PM values was shown in PM indoor / PM outdoor. In addition, based on International Study of Asthma and Allergies in Childhood, Swedish DBH Household Questionnaire and Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ), and in combination with epidemiological characteristics of Guangzhou allergic diseases, observations were made of the symptoms and seizure frequency of anaphylactic disease patients. Also the curative effect of air filters based environmental control means on allergic diseases was evaluated. The questionnaire covered family allergic histories, allergic histories, way of life, living environment, symptoms of AR seizure, seizure frequency, etc. SPSS21.0 statistical software was used for information input and analysis. Descriptive statistics for measurement data. Non-parametric test and repeated measurement ANOVA were used for comparison among groups. Where P<0.05, the difference was of statistical significance.
Results: 1 The ratio of PM0.3, 2.5 and 10 declined (P = 0.001) after the application of air filter. There was statistically significant ratio difference (P = 0.012) between the second month following the application of air filter and the time prior to the use of air filter. 2 According to the RQLQ results, the subjects saw significant drop (P=0.023) in nose, eye and emotional scores one month after the application of air filter.
Conclusions: The application of air filter will comprehensively enhance the indoor air quality and improve the allergic rhinitis patients’ quality of life.
