Made in India..maybe?
Can't tell from the can in the picture. It should have the origin of manufacture on it if imported.
One could always call and inquire as to where they are made. Could be Japan or Korea as well.
If the particle count passes the muster why wouldn't it be good?
Well, usually if you have a good particle count ..you'll have the rest of the filter be of higher quality too ..but there's other factors like ADBV quality and integrity. Some don't like dome end bypass valves ..etc.
You wouldn't like a start up rattle regardless of how good the PC was (I'm speaking of total consumer satisfaction).
