The Clever dripper and the Hario Switch are the two main ones I think, but then there's a lot of niche ones. The overall category is called "immersion dripper".

My main concern is the plastic, so I've got one from a smaller brand entirely made of ceramics. (it's much more expensive though).

The Switch has some plastic and rubber, but the parts that touch coffee/water are all metal and glass.
