This is new information to me. Probably should have already known it, but I didn't
Do they differentiate exactly what type (N number) they are talking about? Likely at least an N95. Most people wearing about an N75 mask, and they do not get clogged nearly as easy as an N95
The mask still works by keeping your spray out of other people's noses. In my world, wearing a mask is about keeping my germs away from other people not the reverse.
The article seems to be saying you have more particle deposition in the upper airway. Even if this is true (it seems this was a modeling paper, not an experimental one), the upper airway is not the big area of concern. The lower respiratory tract is where you run into the most trouble and are at higher risk of severe disease. There would be a benefit if you avoid severe disease (pneumonia and respiratory distress) and can limit the infection to the upper respiratory tract.
Also notable is that the 25 percent figure in the article does not seem to come from the paper they cite. Open it up and Ctrl + F for the number 25. There is not one place in the article with the figure 25% efficacy!
Finally, note that the findings apply to the small aerosol diameters less than 10 microns, which it is well known masks are not that good at filtering. You still get a substantial protection for the larger particle sizes.
All told, the new headline seems to over-interpret/sensationalize the modeling study. The study does not show that used masks are ineffective at actually providing partial protection for the wearer in a real-world environment with mixed particle sizes.

Uh, how do you think it gets to the lower respiratory tract from the upper respiratory tract? Having 'more particle deposition in the upper airway' is a concern.
Wear a mask CORRECTLY (which means over your nose and mouth), try to have it as tight fitting as possible and WASH your cloth masks or toss the disposable ones IN a trash can, NOT in the parking lot.
So disgusting to see these masks all over parking lots. Yuk.

Wow where do you live? Where I live people throw things in the trash and return shipping carts to the cart area. I have never seen masks all over parking lots.

I see it here. While out on walks in the neighborhood and in parking lots. It’s disgusting.
I don’t really understand why people don’t just use re-usable masks and wash them in between uses. Disposal masks are wasteful.
wow. If it were 95% useless because it's dirty - it would not matter - because the mask IS NOT FOR THE WEARER.
it's for the other people. I don't see that data in the study ... do you?
That depends. N95 masks do protect the wearer. The low quality ones most people wear do not. Plus you need to protect your eyes. Covid can enter there also. I wear a face shield or a ND95 with glasses on.
