Let's say fuzzballs are carried in micro water droplets. Indeed, they are so small they can act as water condensation nuclei. Let's assume you breathe moisture containing fuzzballs onto a mask. Sure, the mask will initially catch the moisture. But at room temperature the moisture will not stay on the mask forever. It will eventually evaporate, taking fuzzballs off the mask and into the surrounding air. In the air micro water droplets are too light to fall to the ground and remain suspended in the air as a form of mist, a ground level cloud if you will. Here are two videos showing the effect of mask on moisture breathed out.
Penetration of cloth masks by particles was almost 97% and medical masks 44%.
Conclusions: This study is the first RCT of cloth masks, and the results caution against the use of cloth masks. This is an important finding to inform occupational health and safety. Moisture retention, reuse of cloth masks and poor filtration may result in increased risk of infection. Further research is needed to inform the widespread use of cloth masks globally. However, as a precautionary measure, cloth masks should not be recommended for HCWs, particularly in high-risk situations, and guidelines need to be updated.

Basically, at the scale of viruses, every surface is sticky (due to things like Van Der Waals forces). When a liquid droplet lands on the fiber of a mask, the liquid can evaporate, but a virus (and other dissolved solids) can't. So, even when the droplet has evaporated, everything solid that was in it is still attached to the fiber.

If what you say is true, then masks are what's causing the breakthrough cases. How could you not catch covid with it literally in your face full time?

Surgical masks don't really do much thats not to say they do nothing but the effectiveness of the basic surgical facemask has been in question long before covid

At best they redirect air this may make the area that your breath travels less in distance but it would be the same volumetric wise as little air acctualy will be filtered bye the mask
There is no positive air preshure against the mask material there for there is no power to the actual filtering of particulates
To sum it up there is no possible way to filter air with the current facemasks we have none... literaly none are made to filter exhaled air
This could be done and be done cheap yet hear we are without that solution seems odd considering it might acctualy work

When the water evaporates the viral particle is attached to the mask.
