Yesterday I wore the only type of mask that has a chance (very slight) of warding, the N95. I don’t have a clue if it was successful on that front but I can say with 100 % accuracy that my nose felt it was a mistake. The N95 securely covers all the areas where a virus could seep through tighter than any other paper/cloth type mask in the marketplace including a nose guard and filter to cleanse the air. Yet even with this protection we honestly don’t have a clue whether Covid or any of its more durable strains can leak through. All we can be assured of is if you have a nose the size of mine at the end of just a few hours you will feel the pain, not the gain. The metal guard and cloth irritates your nose to the point of abrasions that simply hurt (OW) . Today I might actually double maks not for the protection but to reduce the pain at least around the nose area. Masking is now the law of the NY Indoor land which is not only a pain in the neck but other parts of the body as well.
