How to find the right coffee filter
The two most common coffee filter types are 102 and 1x4, and both are V-shaped. There are also X-filters, all of which have the same shape and angle. Filters that only have a number, such as 102, have a smaller angle and height compared to X-filters.
Always refer to your coffeemaker’s manual for more information about which coffee filter to use, or check the filter holder.
