So the system is generally called a Melita named after the company Melita, named after the woman who invented this thingy
I personally use a ceramic one I found in a random coffee shop locally, they're a pain to ship, but I prefer the flavour of glass or ceramic (plastic and boiling water are bad together)
The Chemex is the most common device I see for doing it that way, but I definitely prefer my cheap ceramic holder to an expensive chemex.
The filter is a "coffee sock" which is just a fabric one, I almost made one out of cheesecloth, and then I didn't because I have a toddler during a pandemic. The one I have was from a random "coffee supplies" website, but there's a bunch on etsy.
My main issue is that after two years of *constant* use mine are starting to pour slowly, I was recommended to boil them, and I have done so (both in vinegar and water) and it didn't seem to help? So I dunno. Maybe I should use that cheesecloth I bought to make a new one...
