More filters than you can shake a stick at!  We have Filtropa and Bamboo V-shaped paper filters, Chemex filters, conical filters, as well as permanent filters. Wondering which one you need? If you are using a Chemex, use a Chemex filter. For your standard V-shape, flat-bottomed filtercones like the Clever Coffee, Bonavita, Bonmac #2, Bee House Dripper, etc., the oxygenated Filtropas or Bamboo Bonmac filters are the way to go. Cylindrical filtercones like the Bonmac V-shaped Plastic Dripper, Hario V60 Ceramic Drip Cone work with the Hario V Shaped Filters.
