3M Aura Earloop Hack - Dangerous or Awesome? Insane Fit Test Results

Can you hack a 3M Aura to be as good an earloop mask as a KF94 respirator? I Portacount tested a hacked 3M Aura N95 with earloops vs. a stock LG Airwasher KF94. The results were crazy.

Spoiler: I got the best results I've ever gotten from an Aura using hacked earloops.

*Your results will vary*. Don't assume my face and my results will be the same on your face. Mask fit is very individual, and you may get the best fit with a stock KF94. Only your own mask fit testing can tell you (doesn't have to be fancy testing with a machine).

Should you do this? If you use a respirator for work, hell no. Hacking the mask negates the NIOSH certification. This not a 3M or NIOSH approved hack.

If you normally wear KF94s, and you a have access to some form of fit testing, I think it's worth testing how it works on your face. But testing is key.

Really. Please look in to fit testing. A great mask is a great start, but fit testing is what will really help you get the maximum benefit from your masks.
