There are numerous coffee paper filter sizes, brands, and types in the market. The majority of home filter machines in the UK will take a simple flat bottomed 4 cup cone paper coffee filter (also know as a size 4, or 4K).
In general for each size you can use 20 grams of coffee, which will produce up to 300ml of brewed coffee eg 2 cup machine produce about 600ml, and 4 cups top out at around 1.25 to 1.5 litres.
What size coffee filter do I need?
Your machine may describe its capacity as 12 to 15 cups: this refers a cup of about 100ml, and not full mugs. For such a machine use a 4 cup filter.
