Most filters contain a mixture of the following.

1st usually filter wool. Quite fine. Filters out partical matter as soon as water enters filter. MAINTAINANCE: Squeeze out weekly in old tank water. Replace when falling apart or completely clogged.
2nd usually filter sponge. Sometimes just a fine sponge material sometimes a coarse and a fine sponge, depends on type of filter. MAINTAINANCE: Squeeze out monthly in old tank water or when completely clogged up. Dont over clean as some or your beneficial bacteria hang out here.
3rd usually carbon filter material. Not generally needed unless you want to remove medication or dicolouration from your water. Most people here replace this with more sponge or wool.
4th usually your media. Ceramic tubes or such like. Most of you beneficial bacteria hang out here. MAINTAINANCE: leave well alone. If they start to fall apart (takes years) then replace but only about a third at time and leave the new stuff in for a week or so to be colonised with bacteria b4 replacing the next third.
