sorry, NO, the current (20A) is the rating of the filter in hand.

oh...
The meaning of '20A' is an optimum working current or peak current(can't over, like fuse)?

I think it is useless and waste your time to install the filter at the power plug. The cable itself also generates EMI if high current drawn.

Normally the noise filter should be installed inside your machine case (after the power cord) with good connection to the metal filter housing and ground. The EMI problem can be eliminated.
