How filter capacitors work is based on the principle of capacitive reactance. Capacitive reactance is how the impedance (or resistance) of a capacitor changes in regard to the frequency of the signal passing through it. Resistors are nonreactive devices. This means that resistors offer the same resistance to a signal, regardless of the signal''s ...
filter is usually equal to the total number of capacitors and inductors in the circuit. (A capacitor built by combining two or more individual capacitors is still one capacitor.) Higher-order filters will obviously be more expensive to build, since they use more components, and they will also be more complicat-ed to design.

If the capacitors were ideal, there would be no way that smaller value capacitors could filter better at higher frequencies. But every ceramic cap maintains a capacitor-like behavior up to some frequency. Then the parasitic inductance starts to assert itself and ultimately, at high frequencies, dominate the impedance characteristic.
