Chemex does not make a metal filter and does not recommend using one at all.

Yeh, id advise people watch other guides this is not great info for a chemex coffee

Ridiculously poor design placement of the start button on that fancy grinder. I see something like that and wonder what else they did wrong. Throw it out and get an OXO $100 grinder. Good seeing the grind size. No need to wait for it to cool down if you pour it into a room-temp cup. I appreciate the effort and the production quality.

Do Not buy a CHEMEX! You are responsible for shipping to receive your package (approx $20) and if you have to exchange/return you are responsible to find a carrier of your choice and pay for shipping going back. When you call Chemex they never answer phone and you will be disconnected after few minutes . All contact is thru emails , if you get lucky .After getting your Chemex you will be spending hundreds of dollars bcuz you will need a Scale, Burr Grinder , Gooseneck Kettle , Filters coffee beans and after all that after brewing the coffee by the time you even finish your cup the coffee that is left in the carafe is COLD , and yes , you will have to buy another Gadget , a warmer to keep your coffee warm..
