Filtering air is NOT THE JOB OF FACE MASKS!
Face masks help contain respiratory droplets that can transmit SARS-CoV-2, the coronavirus that causes COVID-19, from people who do not know they have the virus.
Another example of a non-entity trying to be clever without the necessary intellect to know fact from fiction.
Mr Stupid and 'Karen' speak a lot of nonsense which is easily proven false but they do not care or move on to another joke idea to show how brilliant they are.
If we can persuade them that masks that stop air 100% from entering the body must be worn, we may have some peace and listen to common sense ideas.
Until then, God help us if they are ever put in charge of something important.
