maybe secondary effects can be stronger than I realized, ? if you have chronic sinusitis from some kind of environmental exposure one way to tell would be to do a deep sinus washing and see if it gives you any temporary relief, however if your still exposed to whatever it well be very temporary relief, I'd say have your doctor do it but I don't know what his office is like, I've been to some that just wiped me out, like new buildings with closed windows and all the new carpet and other man made materials still offgassing chemicals like crazy.

Generic aspects of the airborne spread of human pathogens indoors and emerging air decontamination technologies.Am J Infect Control. 2016 Sep 2;44(9S):S109-S120. doi: 10.1016/j.ajic.2016.06.008.
Indoor air can be an important vehicle for a variety of human pathogens. This review provides examples of airborne transmission of infectious agents from experimental and field studies and discusses how airborne pathogens can contaminate other parts of the environment to give rise to secondary vehicles leading air-surface-air nexus with possible transmission to susceptible hosts. The following groups of human pathogens are covered because of their known or potential airborne spread: vegetative bacteria (staphylococci and legionellae), fungi (Aspergillus, Penicillium, and Cladosporium spp and Stachybotrys chartarum), enteric viruses (noro- and rotaviruses), respiratory viruses (influenza and coronaviruses), mycobacteria (tuberculous and nontuberculous), and bacterial spore formers (Clostridium difficile and Bacillus anthracis). An overview of methods for experimentally generating and recovering airborne human pathogens is included, along with a discussion of factors that influence microbial survival in indoor air. Available guidelines from the U.S. Environmental Protection Agency and other global regulatory bodies for the study of airborne pathogens are critically reviewed with particular reference to microbial surrogates that are recommended. Recent developments in experimental facilities to contaminate indoor air with microbial aerosols are presented, along with emerging technologies to decontaminate indoor air under field-relevant conditions. Furthermore, the role that air decontamination may play in reducing the contamination of environmental surfaces and its combined impact on interrupting the risk of pathogen spread in both domestic and institutional settings is discussed.
