Flaws in using a manufacturer’s SWPF study

Disclaimer: I am NO LONGER a fan of Powered-Air Purifying Respirators (PAPRs). It is not the PAPR’s fault; it is the science behind the increased desire to use PAPRs for all the wrong reasons and how this could be bad news for the users. PAPRs have become increasingly popular over the past decade or so…...
