  • FILTER BITTER BETTER

    Bonded, pre-folded, circle shaped filters ensure uniform extraction for pure coffee flavour. The thicker specialty fibre filter design keeps bitter elements, oils, and grounds in their place (and out of your cup). CHEMEX® filters are 20-30% heavier than other filters and remove even the finest sediment particles. The design of the filter facilitates the proper infusion time by regulating the filtration rate - about a 4 minute brew. They produce coffee with clarity, complexity, and with a light body. One warning: As the filters are made of heavy paper, they require a full rinse with hot water before brewing to remove any paper taste. 100-pack.

    • Pack of 100 filters
    • Compatible with all CHEMEX® Brewers except CM-1, CM-1C, CM-1GH
    • 20-30% heavier than other filters
    • Produces coffee with clarity and complexity
    • 100 filters per pack
    • Made in the USA
    • Place your finger between the 3rd and 4th layer of the filter and open it up into a funnel
    • Place the funnel in the top portion of the CHEMEX® coffeemaker, with 3 layers on the side with the spout
    • The spout acts as an air vent that allows air to escape the lower section of the brewer to let the coffee draw down at the proper rate
    • Gently pour hot water through and around the filter to rinse
    • Empty the water
    • Put coffee into the filter and then brew coffee
    • You can use our method to brew, find one of the many other methods available on the Internet (Here's a good place to start), or use your own!

Work as intended

I prefer the circle filters to the square filters in terms of fit. I find the circle filters are less likely to get caught in the spout, which inhibits drawdown.

As clean as it gets

The Chemex filter is in a class of its own! I own a variety of different brewers and find myself coming back to the Chemex all the time.
I prefer the pre-folded version as its box is smaller and easier to store in my cupboard.

So happy I found these filters at Ratio!! They are sold out in so many locations and I was starting to get worried I wouldn't be able to enjoy my favorite brews.
