I wear a mask when going into a retail store. Not for myself-protection, as in I have never had the flu or a cold in many decades gone past. I have some ailments but my immune system is tip-top.
So...... I wear an N95 mask when going into Home Depot etc as a gesture of respect for those who work there
If you do so that’s up to you and you have a nice motive for doing so. Please wear a cloth mask though. I still have to wear my N-95 for 3 shifts in the hospital then send it for recycling. They are meant for single use. Despite what you here we are short on PPE and it would be great if we could save the medical grade masks for the hospitals
Does it have a hole that pops open for exhaling? If so, then you are only filtering while you breathe in and if you have COVID, you are exhaling all of your infection.
