I have an action / reducer / components. In one of my components (component dump) I have a Select. I get information on what type of filter my store. Where can I handle it in action, or reducer?

Some users prefer to keep every single piece of data in Redux, to maintain a fully serializable and controlled version of their application at all times. Others prefer to keep non-critical or UI state, such as “is this dropdown currently open”, inside a component's internal state. Using local component state is fine.
For the most part if you have a react-redux app I would avoid local state entirely unless you can trying to solve a very component specific problem. For example I would use local state if my component does something on a setInterval and so it is keeping its own timer.
We specifically recommend organizing your logic into "feature folders", with all the Redux logic for a given feature in a single "slice/ducks" file".
A store is an immutable object tree in Redux. A store is a state container which holds the application's state. Redux can have only a single store in your application.
IMO, the right place to sort data is not directly in the reducers but in the selectors.
From redux docs:
Computing Derived Data
Reselect is a simple library for creating memoized, composable selector functions. Reselect selectors can be used to efficiently compute derived data from the Redux store.
I'm currently using selectors to filter and sort data.
