Your layer height could be 0.2
Shell thickness is a multiple of 0.4, so that's OK
Bottom and top thickness is too low, make that bigger, like 1.0. You bottom/top thickness should be a multiple of you layer thickness, preferably 5 or 6 times. So with the settings you have now you would only get 2 layers...
In the preview, only the top 10 layers have an accurate appearance, the ones below fade out.
The mesh on the bottom of your filter is probably too thin, wall thickness below 0.4 cannot be printed.
