  1. a Between the hours of 7 am – 10 pm, the cat allergen concentration increases for 33% from the intermittent allergen release. Emission rates based on Custovic et al. [76].
  2. b A total of 8 cigarettes per day. Per cigarette emission rates (mg/cigarette) based on Klepeis et al. [46].
  3. c Emission rate of infectious doses (or quanta) per hour (q/hr) based on Liao et al. [56].
