Here is a good article on this topic.

"Sling filters are basically OSGi services which are implementing javax.servlet.Filter interface. They are mostly used for authentication of request, post processing of markup or adding/modifying some request parameters etc. Sling supports filters by applying filter chains to the requests before actually dispatching to the servlet or script for processing."

Thanks Jitendra can you provide any real time scenario example

 Let's suppose, you want to meet any govt officer and before meeting to him, you have to go through peon (big boss) and he will do the checks before granting permission to you. 

In similar fashion, any request comes to AEM system, go through these filters and these filters do the verification of the call.
