About this item
Product details
Our CHEMEX paper filters are based on laboratory grade paper and designed specifically to filter out impurities, unhealthy and bitter elements from the coffee. Not your average coffee filter, our heavy weight bonding makes them 20-30% thicker.
It is a misconception that metal filters, percolation or plunging methods brew a “stronger” cup of coffee. In fact, what is being tasted are leftover flavors of the fats and sediments which mask the full flavor of the beans.
By using CHEMEX filters you are able to brew coffee as strong as you’d like, without acidity and bitterness. In your cup you will find only the caffeine and flavor from the desirable aromatic oils of the coffee beans. Our specialized paper works well with light , medium and dark roasts- even tea! Allowing you to make the perfect and most pure cup every time!
The CHEMEX brewing system is a preferred method of roasters and baristas worldwide to showcase the spectrum of tastes found in their beans.”
All CHEMEX Coffeemakers used together with the scientifically designed, patented CHEMEX Bonded Filters, will guarantee that our pourover brewing process will deliver the perfect cup of coffee, without any sediments or bitter elements.
100 filters per pack.

Best Filters!
These are just by far the best filters!

great filters
A must if you have a chemex or similar product. They allow for the air to escape, so... no bubbling, or splattering, like other filters. Slow filter for a perfect pour.

Best drip filter for chemex carafe
This is the only coffee filter I will use. It is designed to let coffee drip slowly into the chemex carafe to obtain maximum flavor and smoothness. I highly recommend it!
