Dispenser pack of (100) Chemex FS-100 Bonded Filter Squares.

These filters will work and are designed for all sizes and styles of Chemex Coffee Brewers except the small Chemex CM-1C & CM-1 models (pint size models) 1-3 Cup Coffee Makers.

Chemex filters remove even the finest sediment particles as well as the undesirable oils and fats. The formulation of the filter permits the proper infusion time by regulating the filtration rate - not to slow, not too fast. Good infusion of the coffee grounds (as in brewing and steeping tea) gives coffee a richer flavor while at the same time making possible precise fractional extraction: filtering out the undesirable components which make coffee bitter by allowing only the desirable flavor elements of the coffee bean to pass through.

The Chemex filter is folded into a cone shape, exactly as in laboratory techniques. This assures uniform extraction since the water filters through all the grounds on its way to the apex of the cone. The Chemex filter is guaranteed not to burst under the weight of the liquid during filtration, and not to break when lifting out the grounds.

Fully-bodied, richer flavor, from less coffee, and as strong as you like without bitterness - that's what the Chemex filter gives you.

These are the best filters for pour overs out there. Very happy w this transition w espresso parts



If I could have given a ten star rating I would have. From the ordering to the shipping speed Espresso Parts is awesome. I desperately needed Chemex filters and was down to just a few. I had placed an order from a well known retailer weeks before, and they kept back ordering the shipment. Thankfully Espresso I discovered Espresso Parts and called to see if the filters were readily available. The person I spoke to was wonderful. As I sit here enjoying my coffee, it gives me great pleasure to submit my rating. You folks are the greatest!


The filters are exactly what I needed, and were delivered promptly. Thanks!


Came quickly!

Great communication. Order arrived quickly. Chemex is my go to and these are my favorite filters.


Excellent quality!!!


Honestly, I'm a die hard Chemex user. Nothing newly amazing to say about wonderful Chemex products. HOWEVER, the price on the filters just keeps going up and up. Use to be able to buy a box for less than $7. NOW can't find any for less than $8.50 PLUS the $4 cost of shipping and tax. Equaling over $12.50 a BOX!!! Egad! So my husband thought I was crazy. But I went for your "free shiping" over $150. offer, and you did not charge me tax. Paying only the $8.50 a box. Sooo we have enough Chemex filters to last us FOUR+ YEARS now!!! All at a great price! (Coffee filter family investment plan) THANKS!!!
