I have a La Pavoni Europicola and my filter looks the same. It looks like 
every hole has an indentation in between. I believe that this is 
intentional, and probably has something to do with how the part is clamped 
in order to stamp or machine these tiny holes. So, I suspect, that if you 
order another you'll have the same thing. Are the holes/indentation in a 
regular pattern or irregular? If irregular, then you might have a 
manufacturing defect.

I've one of those chrome La Pavoni home pump machines, known variously as
"Inn" or "Pisa" or whatever. I unscrewed the screen for cleaning and noticed
that the holes do not go all the way to its edges. That is, there are
indentations, but it's not perfectly flat (concave when in place) and it
looks like, maybe, at manufacture, there should have been perferations at
each little dent, but they stop about half way out.
I'm wondering (1) if this is intentional--my suspicion is that it's not--and
(2) if I would get different performance with a new screen (presumably 
hole-y
all the way across).
