When in doubt, just take a SIMPLE test.. If wearing a whatever mask/respirator and one can still SMELL car parfume in a car OR toilet freshner fragrance/ammonia in a public toilet, that means that mask is offering ZERO protection.
Ammonia smell = Previous unknown toilet user's evaporated urine..
Fake..! Where do you learn this? Ammonia smell = Previous unknown toilet user's evaporated urine..
Not even N95 can filter ammonia smell or any toilet freshener. You need to use respirator with filter that contain smell absorber like charcoal to do that...LOL
