WARNING : Portable Oxygen Concentrator's Do not Filter out covid-19 If you use them, they just suck the air around you. Up into your Nose??? I just found this out today. I am going to use my Oxygen Tank next time I have to go to the store. I am trying to find a way to put a filter from my Mask to cover the Filter on my Concentrator ?
