Corsair 750D question

[mojothehut]

Hey guys. Looking for anyone who has experience with the Corsair 750D.

Kind of a dumb question, but curious how fine the magnetic dust filter for the top fan vents is. I'm considering replacing my Antec P280 with the 750D.
I hate dust and am already worried about it. I don't plan on using the top fans so will want the filter in place. Kind of wondering how porous it is. All the pictures online I've seen it looks fairly lame, just a metal grate? no mesh?

Edit: NVM.

Im not sure there is a top filter in that case. On my carbide air 540 there is a front magnetic filter, but nothing for the top.

Apparently that metal grate/mesh panel on the top is considered the top filter

There is no mesh on the top vents. Only on the front and bottom where the PSU intake is.
