They baffle the out flow a little bit, because it is sucking in water slower, but its not a whole lot. It's also good to protect the betta fins from the intake. I actually baffle my intake and outflow, but I don't have one of these handy things, I just stuffed some filter sponge in the intake.. gets kinda gross sometimes, haha, but its probably just that good bb? Right? Thats just what I tell myself to feel better when I have to touch it..
I've never seen one of those in person, but it looks like a pretty soft sponge, what if you got two and cut one long ways sorta like the pop bottle baffle and used it as an out flow baffle?
