About
The goal of this clinical trial is to evaluate the efficacy of air purifiers in reducing allergy symptoms in patients with a cat allergy. The main question it aims to answer is:
If there is a reduction of early asthmatic response (EAR) compared to placebo.
Participants were asked to remain in an exposure chamber for 2 hours while their symptoms were monitored.
Full description
For this protocol, 30 patients with cat allergies were exposed to 80ng/m3 of Fel d 1 allergen in the ALYATEC Environmental Exposure Chamber (EEC).
The active group of 15 had Dyson BP06 air purifiers running at speed 2, while the placebo group had the purifiers on, but not circulating air (speed 0). Participants were monitored for the primary objective of reduction of EAR, alongside other secondary objectives:
