Do you have a source for that? The recommendations I've seen suggest otherwise, and this matches my intuition. Wear creates and enlarges pores, and also, pores

Wear creates and enlarges pores, and also, pores of the right size get clogged resulting in more flow over pores that are too large to filter.
- Scoundreller 7y agoDepends on what's hitting the filter. All "wear" will enlarge pores by definition, otherwise it's not wear. And in your example, if pores are 0.1-0.3micron, and you have uniform 0.2micron particles hitting it, yes. But reality isn't usually so uniform. Shards of glass will create more problems for the filter media than shredded N95 mask dust :) A mask covered in saw dust will slow down and make a particle hit against the filter more turbulent = less chance of forcing its way through.
