A filter set is a group of filters that allow you to analyze a specific subset of your data.

For example, you may have done a survey of all people in the US and you may want to focus only on men in Maryland. Create a filter set where 'gender' variable equals 'men' and 'state' is 'Maryland'. Apply it and new analyses will be run on that subset of your data.

You can create and switch between different filter sets to quickly segment and drill down your data.
