If mask were effective and the virus was “trapped” in the mask, wouldn’t the mask then become bio-hazard and dangerous to handle and disposed of?
Having worked in a hospital when I was young I came in contact with patients in isolation and there was a strict protocol on what to wear into the room, and how to dispose of the hat, gloves, MASK and gowns when leaving the room. There were RED BIO HAZARD bins for these items and they were burned.
Yet millions of mask were just tossed in the trash (or the street) and nothing was said.
I did my part. I had one mask in the car and used the same mask for the entire time. Putting it on when I was forced to and taking it off as soon as I cold.
I did not get covid or the flu.
I had to wear one when I went to my chiropractor. They had those timed scent aerosol spray things and I could smell it. Even with a mask on, I could tell what fragrance it was. If a spray aerosol could get past a mask, so could Covid. After that experience, I didn’t wear my mask. No one said anything about it either.
