How to block all but one item type from chests

factorio

When using the Logistics network it happens often that my robots put unusable items in chests that exist only to feed a specific assembling machine.

In train wagons you can add a filter to each inventory slot so only items of that type can be put in that wagon by placing at least a single item in the slot and pressing +.
I've tried the same with chests (and all other combinations of modifier keys and mouse buttons).

Is there another way I can prevent items I don't want in a chest from being put in there?

If you have a requester chest you can set the type and quantity of the items that you want to be delivered there. I've never had robots put things in there that I don't want, however if it is a storage chest then the robots will dump anything that can't go anywhere else in there, this can clog things up if you have active provider chests as opposed to passive provider chests. I have never really needed to use active provider chests so I don't run into that issue.
