7 Best Chemex Filters (Metal + Reusable + Paper Filters)

Henry Muller

Have you ever found those sediments once you brew coffee using a Chemex?

The culprit may be the filter that you are using while brewing.

The Chemex brewing method is renowned among coffee enthusiasts for its clean and flavorful cup of coffee. The filters you use during the coffee-making process play a crucial role in keeping your coffee clean.

In this article, I will give you a list of the best filters that you can use while brewing Chemex. Along with this, I have also included a buying guide that will help you choose the right filter.

Let’s start.

Things to consider when buying a coffee filter for Chemex

1) Size of the filter

There are different sizes of Chemex coffee makers available such as 3-cup, 6-cup, 8-cup, and 10-cup models, so it's essential to choose a filter that suits your specific model.

For efficient brewing using the filter of the right size is essential. Too large or too small filters can result in an uneven extraction.

2) Filter material

These filters come in different materials, including paper, metal, and reusable cloth. Each material has its own pros and cons. For example, if you want filters that can be easily disposed of and can produce a cleaner cup then paper filters are feasible.

For a full-bodied cup with more texture and flavor, you can pick metal filters as they are reusable and environmentally friendly. To maintain a balance between paper and metal filters, cloth filters that allow some coffee oils and fines to pass through can be used.

3) Thickness

Thicker filters yield a cleaner cup of coffee with fewer oils while thinner filters result in a richer and more delectable cup.

Thus the thickness of the Chemex filter can strongly affect the flavor and texture of your coffee.

4) Shape

Chemex filters come in different shapes, including square and circular.

Square filters are folded into a cone shape when positioned in the Chemex, while circular filters are pre-folded and require no effort. The choice varies as per individual’s preference.
