Hey, Apatel just posted a link to this in another thread:

Turns out PG has been used as an air sanitizer and anti-microbial in places like hospitals for years, and was reapproved for that purpose in September, 2006.
Edit - says it works against bacteria and some viruses! Targets are:
"Odor-causing bacteria, Fleas, Mites, Red lice, Animal pathogenic bacteria (G- and G+ vegetative), Shigella bacteria, Pasteurella bacteria, Listeria bacteria, Herpes Simplex I and II, Animal viruses, Influenza Virus A2, Aspergillus Niger Fungus, Mold/Mildew, Pseudomonas SPP., Shigella Flexneri, Shigella Sonnei."
