By the time you get to the filter caps, it's way too far from the problem to effectively fix it. If you look at the combined impedance of any reasonable size film bypass across an electrolytic it doesn't help. Parallel caps in RF and logic circuits can work (see Jim Williams) but pitfalls abound without measurement.
The dissipation factor for film/foil capacitors is lower than for metallized film capacitors, due to lower contact resistance to the foil electrode compared to the metallized film electrode. The dissipation factor of film capacitors is frequency-, temperature- and time-dependent.
A film capacitor, also known as a plastic film capacitor, uses plastic film as its dielectric. There are many types of capacitors, including electrolyte capacitors, paper capacitors, film capacitors, ceramic capacitors, mica capacitors, and air capacitors.
While ceramic capacitors offer better dv/dt capabilities, film capacitors are good (with a maximum value of 2200 V/µs) making them suited for use in snubber circuits. Film capacitors also have low equivalent series resistance (ESR), low equivalent self-inductance (ESL) and can tolerate large peak currents.
There are two different types of plastic film capacitors, made with two different electrode configurations: Film/foil capacitors or metal foil capacitors are made with two plastic films as the dielectric. Each is layered with a thin metal foil, usually aluminum, as the electrodes.
A thin film capacitor is a type of film capacitor, which is a capacitor with a metal foil as an electrode and a thin film such as polyethylene, polypropylene, polystyrene, or polycarbonate, that is overlapped from both ends and wound into a cylindrical structure. (Typical schematic diagram of thin-film capacitors)
Metallized film capacitors are not affected strongly by DC bias. Their volumetric efficiency is not as great as that for multilayer ceramic chip (MLCC) capacitors or electrolytic capacitors. These capacitors (as well as ceramics) are used in safety applications for EMI/RFI reduction and safe failure modes.

Capacitor safety precautions1. Identify the requirements The first step is to identify the requirements for the capacitor in your circuit, which means the value and type of capacitor you need. Circuit testing and troubleshooting.
Subclass X2 and Y2 are the most common type of subclass for applications that use 120VAC (USA) or 220/240VAC (Europe). X/Y combination capacitors are also available, so you might consider using one of these, as well. Whichever safety capacitor you choose, make sure that it has all the proper safety-approval logo markings.
Even if the test based on the capacitor standard is passed, this does not ensure comprehensive protection against all pos-sible overloading. Currently, a number of customers are requesting special tests on unprotected capacitors with extreme overvoltages and temperatures to prove safe capacitor per-formance.
To be clear, you should select your Class-X and Class-Y capacitors according to your design's purpose and requirements. Whereas X2 and Y2 caps are appropriate for household applications, X1 and Y1 safety capacitors are used in industrial settings.

Power capacitors can actively fail when internal or external protective devices are missing, incorrectly dimensioned or have failed.
These safety capacitors are also known by other names, including EMI/RFI suppression capacitors and AC line filter safety capacitors. (EMI stands for electromagnetic interference and RFI stands for radio-frequency interference; RFI is simply higher-frequency EMI.) Figure 1. An example of a Class-Y capacitor.
