# Filtering

In a [push based approach](http://reactivex.io/rxjs/manual/overview.html#pull-versus-push), picking and choosing how and when to accept items is important. These operators provide techniques for accepting values from an observable source and dealing with [backpressure](https://github.com/Reactive-Extensions/RxJS/blob/master/doc/gettingstarted/backpressure.md).
