All the filters will function in the same way, it just comes down to personal preference for which you choose.  The white filter paper goes through an oxygen cleansing bath followed by a series of hot water baths.  The brown filter paper goes through only the hot water baths, retaining the “natural” wood color.  We don’t use any bleach or chemicals in our filter paper.  They are both compostable.   

All the filters will function in the same way, it just comes down to personal preference for which you choose.  The “halfmoon filters” (itemcodes FP-2, FP-2N) for the 3 cup and Funnex do not come pre folded due to their design and size.  We offer pre-folded circles and squares for your convenience.  However, some people prefer to fold their own circles and therefore we also offer the Un-folded filter circle (item code FP-1).

All the filters will function in the same way, it just comes down to personal preference for which you choose.  Some people like the points on the square filters for easy removal, while others prefer to have the top of the filter flusher with the carafe. The FP-2 and FP-2N filters are a “halfmoon” in order to fit into the 15 ounce brewers.

We measure our cup size in 5 ounce increments.

Yes!  The glass coffeemakers can be put into the dishwasher once the collar and rawhide are removed.  However, to avoid breakage please be sure that the carafe is secure and not bumping up next to any other dishes. You can also hand wash the carafes using this coffeemaker brush.

• Remove the collar and tie and handwash. 
•  Swirl warm soapy water in the carafe and rinse. 
• Use the coffeemaker cleaning brush 

Lovingly referred to as the “bellybutton”, it indicates the halfway measuring point on the coffeemaker for sizes 5 to 10 cup and the full line for the 3 Cup coffeemaker. The 13-cups lower bellybutton marks the halfway point, the upper bellybutton marks a full pot.

This is purely an aesthetic difference in the design and does not change the functionality of the coffeemaker.  

Yes!  You can make up to the ounce amount of the size coffeemaker you have or make less. Just adjust your coffee and water recipe to brew however many cups you would like.

None of our products should be reheated in the microwave.

The glass for the Classic Series and Glass Handle series are made in both Taiwan and Germany. The glass for the Handblown Series is made in Croatia.

• There is no difference in how they function.  All our coffeemakers are made with high quality borosilicate glass and will produce the same fantastic results. 
• The Classic Series and Glass Handle series are machine made while the Handblown coffeemakers are blown into molds by skilled glassblowers in Croatia. 
• The glass used to form the Handblown coffeemakers is thicker, a little heavier, and has a very slight green color.
• There are no logos on the Handblown coffeemakers. 
• The glass used for the Classic and Glass Handle series is thinner, lighter in weight, but still a very high-quality borosilicate and is crystal clear.  These coffeemakers will have either have our "X" logo or have "CHEMEX" in white lettering on their base.  

We offer many different and beautiful glass handle coffeemakers that are made fully from borosilicate glass.

No! The CHEMEX was literally invented so that brewing delicious coffee was easy and fun. With just a little practice, you can quickly master the technique of the CHEMEX pourover.

Any type!
The CHEMEX works very well for light, medium and dark roasts- even tea!

This is not a required step in the brewing process.  One may do this to rinse away any remaining paper fibers as well as heat the carafe. Be sure to dump out the water before beginning to brew the coffee.

This is so that the filter doesn’t collapse into the spout, as it is used also as an air channel during the brewing process.

Use a medium coarse grind. This will allow for the best extraction and flow rate will brewing the coffee. For more information go to our brewing page.

Giving your coffee time to “bloom” enhances the flavor of the brewed coffee beans. The bloom is escaping gas that has been trapped in the beans during the roasting process.  Once this is complete, water can freely extract the aromatics and coffee oils while brewing.

The coffee is ground too coarse, and the water is passing too quickly through the larger coffee bean particles. Use a less coarse grind.

• The coffee is ground too fine and is clogging the filter. Use a coarser grind. 
• The Spout is sealed off by the filter. Please make sure 3 layers are on the side of the spout.  
• We sell a filter vent clip that can help with sealing against the glass.  

• There are several ways to keep the coffee warm: 
• The carafe can be kept on a low flame on a gas stove. 

1. The carafe can be kept in a warm water bath. 
2. The carafe can be put directly on a glass top stove on a low temperature. 
3. We sell a wire grid (TKG) which can be placed on an electric coil stovetop which the carafe can then be placed on. The stovetop must be on a low setting. 
4. One can wrap a towel around the carafe 
5. You can use the CHEMEX glass coffeemaker top  
6. Pour your coffee into a Chemex thermos and it will stay warm for up to 8 hours. 

The CHEMEX is what all those other coffeemakers strive to be. Invented in 1941, it has never needed to be altered or improved upon. Winning awards in both the design and science communities, being kept in permanent collection of some of the most prestigious museums in the world, are just a couple pieces of its iconic history that none of the others can boast. Widely considered to be one of the best ways to brew the perfect cup of coffee; the CHEMEX has been the choice of coffee lovers globally for over 80 years and counting.

Yes!  You can brew loose leaf or tea bags in the carafe using your ratio and temperature preferences.  Or, you can filter it through the paper filter, based on your own recipe preferences.

The brush is flexible, and it bends to easily clean hard to reach places.  It may be folded when first delivered to you, simply bend the wire bristles out before use.

Yes, it is.

The glass coffeemakers can be put into the dishwasher once the collar and rawhide are removed.  However, to avoid breakage please be sure that the carafe is secure and not bumping up next to any other dishes. You can also hand wash the carafes using this coffeemaker brush. The other glass products can also be put in carefully in the dishwasher, after all non-glass parts are removed. They can also be hand washed.

1) Fill the water tank with water and our CHEMEX cleaning solution to the 8 cup level. 

2) Run the brew cycle to fully flush the cleaning solution through the brewer to clean and de-scale. 

3) After cleaning/de-scaling, rinse the system by running a minimum of two brew cycles using only water. Allow for a 5–10-minute cool down period between cycles. 

* We recommend descaling every 40 brew cycles or every 3 months whichever comes first.
