No, im talking about the effectiveness of protecting others. The studies were all done about stopping or slowing the spread of a virus.
https://www.cdc.gov/coronavirus/2019...recent-studiesAnd.....helping reduce is bad? I’m not understanding what point you’re trying to make.
CDC website says to wear a mask, and goes in to specifics of why and what types. What part of their website is giving you the impression that their stance is “only wear good masks, otherwise don’t bother.”
That is the part of the website that they use to give "evidence" that cloth mask mandate is good. The very last few studies are what you're after. Read em. Very enlightening. That is where you find the information that they need Multiple layers or a filter, as well as to be tight fitting, to really have any impact of helping to slow the spread.

As you stated on your own, if you have difficulty breathing, you are advised Not to wear one by the CDC. Then you say you should, nonetheless, wear one? Not how it works. You get a mask that lets someone who has issues breathing that is made of a material that lets them breath, you have a mask that is different in its effective levels.
Just doing a quick google research, the mask types I see recommended for someone who can't breath are a gator neck one, and a bandana. You'll find both of these types Highly ineffective to prevent the spread since they are loose fitting and not capable of blocking the virus well, if at all.
I get it. People are angry that those who can hardly breath don't want to wear a mask. That being said, we need to be realistic. Anything that will allow them to breath well is not going to be effective at stopping them from spreading covid if their sick. That is the reality of it. Wear one. By all means. However, regardless of having a mask, I am not going to pretend their some catch all or even that great at reducing it. Its basically a situation of throwing everything they can at it, even if it helps Just a little, because our country can't manage to get it under control while the rest of the world is returning to normal and blocking us from going there.
They need a lot more than masks to get this under control. Even if a study I can find, they only help by Maybe 2% reduction. A point thats moot with the opening up and lessening of other restrictions.
Video is very informative. Highlights that masks are useless if you still wont social distance. Testing that shows most masks will still allow you to spread to within a foot. These are meant to be used with social distancing. Not alone. A point a lot of people don't grasp.
