I guess I used the wrong term! They are like sponge "bubblers". They just put air bubbles into the tank. Most betta kits seem to come with those and they don't really filter the tank. I forgot there are also sponge filters, which I heard are quite effective!
I think I actually have something like you pictured around. I just have to find where I put it.
