The filters in the two types can be referred as pre and post filters also. As @alexey explained, root level filter is performed after query and filter in filtered query is performed before the query.
In addition you need to understand the impact of the same other then the order they are executed. The filter in "filtered" query comes under the query scope which means that while calculating aggregations the filtered output will be considered while in case of the root level filter aggregations will be performed only on the results of the query excluding the filter. Though in both case the result documents will be same.
For example with the two queries you have posted, both will give same results, but if you are performing aggregations also the first query will calculate aggregation count from documents matching title kitchen3 and price 10000 while the second query will calculate aggregation count from documents matching title kitchen3 only without filter of price 1000.
