Coffee Filter Paper Sizes & Types: Choosing the right filter for your brew
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.
