For clearing custom filters you can use primefaces resetInput, along with clearFilters() discussed in other answers, and a custom actionListener method. See code snippets below:

Controller.java

public void clearAllFilters() {

    DataTable dataTable = (DataTable) FacesContext.getCurrentInstance().getViewRoot().findComponent("form:dataTable");
    if (!dataTable.getFilters().isEmpty()) {
        dataTable.reset();

        RequestContext requestContext = RequestContext.getCurrentInstance();
        requestContext.update("form:dataTable");
    }
}

I hope this helps anyone looking to clear custom filters.
