Chainsaw Repair

While working on dads 3300 I noticed it had some flocking missing on the air filter. Which I will try BB redneck fix later on.
Anyhow I ask dad where is the new filter I bought him years ago. He stated hanging up. So I told him to bring it up with him last weekend. Turns out I had bought him a NOS mesh one.

Now my question being that I have a NOS 530010855   mesh air filter and NOS 530010892  flocked air filter. Which would be better for him? Which one would you think would be better trapping fines?

I never paid any attention to them or any filtering difference etc in the past.  I am leaning toward putting flocked back on his saw.
