Event 1: Air freshener was sprayed twice in an unventilated area, first 1 metre away from the device and then 30 cm away from the device. There is a small increase in PM2.5 concentration, followed by a sharp increase in VOC concentration.
Event 2: Multipurpose polish spray had the least effect on the IAQ, with the spikes only reaching the lower end of the amber range for both PM2.5 and VOC concentration.
Event 3: Hairspray had the highest spike of PM2.5 concentration, reaching 427μg/m3 and then rapidly reducing to 58μg/m3 within a space of 5 minutes. VOC concentration immediately after PM2.5 concentration increased.
For all conditions, VOC concentration reduce after a long period of time due to the lack of ventilation so it takes longer to remove from the air. Better ventilation is required to reduce the time taken for VOCs to leave the air, by opening windows, using an extractor fan or using an air purifier.
