True, but I was responding to a poster who asked about protecting themselves. An improperly fit N95 would provide the same amount of protection for others as a surgical mask.To do a quantified fit test takes a trained technician, but getting any sort of respirator to fit properly is really quite easy, from my experience. And even a poorly fitting mask (N95 or not) is going to do a decent job of stopping you from expelling aerosols as long as it covers nose/mouth.
Last time I did a fit test they had me move around while I wore it, and it was really eye-opening how easy it is to inadvertently lose your seal.
