Actual (reported)Effect of active nasal filters compared to placebo filters in the same patient group as measured by difference in maximum Total Nasal Symptom Score
To assess the effects of active nasal filters on symptoms development in patients with seasonal allergic rhinitis (SAR) exposed to air-born allergens compared to the same patients in an exposed environment with a placebo nasal filter determined by their maximum Total Nasal Symptom Score (TNSS) out of the nine samples taken during a trial day. The statistical analysis will be done using non-parametric paired Wilcoxon signed rank test.
