Cone-shaped filters come in various sizes, with the most common being #2, #4, and #6. These filters are used in pour-over coffee brewing methods and are made to fit specific sizes of drippers or cone-shaped coffee makers. Check what filter size your machine takes, and then we recommend you get the unbleached version. We can recommend If You Care and Melitta brand filters, which are widely available, brew well, and offer unbleached versions of all 3 primary cone filter sizes
The main difference between cone-shaped filters #2, #4, and #6 is their size and shape.
- Filter #2 is the smallest of the three, and it is designed to fit small, single-serving pour-over drippers. It has a base measurement of around 42mm and a top measurement of around 57mm.
- Filter #4 is slightly larger than filter #2, and it is designed to fit medium-sized pour-over drippers. It has a base measurement of around 57mm and a top measurement of around 72mm.
- Filter #6 is the largest of the three, and it is designed to fit large pour-over drippers or carafes. It has a base measurement of around 72mm and a top measurement of around 87mm.
It’s important to note that these measurements may vary slightly depending on the brand of filter. It’s important to check the measurements of your dripper or cone-shaped coffee maker to ensure you choose the correct size of filter. The wrong size filter can cause your coffee to brew too fast or too slow, affecting the taste and quality of your coffee.
