   The primary advantage of using a L or Pi filter (rather than a brute
force {just capacitance} filter) is the reduced amount of energy stored
in capacitance which is undesirable when an arc is experienced.
The extra storage energy and the lack of inductance (which reduces the 
amount of extra current from the rectifier/s) add to the amount of 
energy that shall be dissipated in the tube/s or other fault.

   It is a safety thing.  (for the tube/s)

   Pi filters are seldom used for low Voltage supplies (100. Volts and 
under) because little "arcs" at these Voltages.
