Some projects are pretty simple ”they contain only a few tasks or resources, and it's easy to keep track of them onscreen in your views. However, there are those projects that are very large and take up many, many screens of data. Finding that certain set of tasks or resources you are looking for in this situation can be difficult. Filters allow you to limit the data shown onscreen so it's easier to find the information you need.
