I’ve just scanned through the full report.  It says some of these disposable respirators don’t work as well as they should.

My question is which ones work best?

But I can’t see mention anywhere of which models and manufactures are the best.

This is a complete waste of everyone’s time and effort.  We’re told some respirators don’t work as well as others.  What am I supposed to do with this information?  It’s of no value whatsoever, in fact it’s wasted some of my time.

Sorry, rant over, I was just so irritated by all the facts and figures and the obviously large amount of work this involve, all to no avail, I can’t do anything with this information.

Thank you for you patience while I rant...

(Perhaps I've missed the manufactures' names, I just can't find them :-(  )
