Consider safety first when it comes to air purifiers

Strange but it is true. It is very, very hard to get well organized, properly documented scientific research about the technologies behind air purifiers, a multimillion dollar global industry!

It is strange because if the science is soundly grounded, I would expect an air purifier manufacturer to understand the scientific basis of their brand. I would expect them to expound the effectiveness of their unique technology. Even more, I would expect them to assure users that their technology is perfectly safe, that they kill microbes but are perfectly harmless to the human beings. Unfortunately, my expectations are not met. 

True because I have spent unlimited hours looking for scientific technical papers supporting the technologies behind the current air purifiers and bathroom exhaust fan available in the market and still have very little to show for it. Whether deliberate or not, marketers of these products just don’t bother to put up scientific papers on their websites. Where they do, they make no distinction between effectiveness and safety of their particular brands. The scientific references are mentioned only in short and do not offer sufficient detail for study by serious potential buyers of the particular air purifier.

Human testing

In the final analysis of the window exhaust fan, does this imply that there is truly no safety testing for the impacts of the active agents on human beings, who utilize air purifiers? It will be hardly if you consider it. All the users unknowingly become testers by the act of buying one and using it. 

Sadly, all we will hear on the manufacturer websites would be the nice testimonials about the advantages of the purifier. Such testimonials, although beneficial, come under the cloud of cherry picking, that is only the positive ones are published.
