Excellent coffee and a free "brain puzzle" for free!
Style: Square
I love Chemex products. I have had 2 pots over the years. They always make a fantastic cup of "melitta-style" drip coffee that to me , has better overall flavor. I wonder if it might not be the chemistry-grade glass? Something Walter White might have used in Breaking Bad to start his breakfast. The filters are a bit of a Chinese paper puzzle until you become used to them. The only filters I buy are these Chemex bonded Filters/Square. Hey, doesn't everyone need a good Chemex Bonded Square Filter in the morning to get the brain in gear?

Excellent for DIY Espresso Basket Filters
Style: Circle
I purchased these Chemex filters for a different purpose than traditional pour-over coffee. I use an EK Tools 2-inch circle punch to make paper filters for the bottom of my espresso baskets, and they have worked exceptionally well. Because each Chemex filter is folded into four layers, every punch creates four paper circles. I can fit about four punches on each filter, giving me approximately 16 espresso basket filters per Chemex sheet, making this a very economical option. The paper is thick enough to cut cleanly with the punch, and the finished circles lay flat in the basket without curling or bunching. Since switching to these filters, I’ve been able to grind noticeably finer with my 1Zpresso J-Ultra while maintaining very even extractions with almost no visible channeling. The bottom of the basket stays much cleaner after each shot, and cleanup is as simple as peeling away the paper with the puck. The biggest difference is in the cup. I noticed a cleaner, brighter espresso with improved flavor clarity. There is a slight reduction in body, which is expected when using paper filters because they capture some of the oils and fine particles. I mainly drink lattes, so the reduction in body is minimal for me, while the improved clarity is still noticeable. If you’re looking for an affordable way to make your own espresso basket filters, I highly recommend these. I included photos of my setup, the punched filters, and the puck after extraction to help anyone considering this DIY approach. Overall, this has been an inexpensive upgrade that noticeably improved the consistency of my espresso.

Best pour-over filters!

Stronger than the little grocery store "cone" filters, which I have seen burst and fail. Easy to use, nice no-bitterness coffee.

A must-have for any Chemex coffee lover!
Style: Square
Absolutely love the Chemex Bonded Filter - Square - 100 ct! These filters make such a noticeable difference in the quality and taste of coffee. They filter beautifully, creating a clean, smooth cup without bitterness or sediment. The quality is excellent, they fit perfectly in the Chemex, and they hold up well during brewing without tearing. I’ve tried generic versions before and always come back to the originals because the difference is worth it. A must-have for any Chemex coffee lover!

CHEMEX FILTERS Are critical to a GREAT mug of coffee
Style: Circle
I just got my FIRST CHEMEX 8 cup carafe and these filters. I see a noticeable difference from other filters I have used in the past for drip or mechanical coffee makers. I BELIEVE THE FILTERS ARE THE MOST IMPORTANT piece of this coffee puzzle! I got the circle unbleached filters as the CHEMEX carafe is a circular drip maker. Seemed easiest to use. I have bleached CHEMEX circle filters on order to see if there is a taste difference I can discern. USE THESE FILTERS in whatever coffee maker you have...a mug, a drip, a mechanical drip...use CHEMEX FILTERS! The CHEMEX filters are much thicker than doubling up other brands of filters....So there must be more than thickness of material involved in a GREAT CUP of COFFEE. I'll, eventually, try the square CHEMEX as well as the bleached CHEMEX filters...just ....because.... HeEre's my review of the CHEMEX 8 cup CARAFE "I received my CHEMEX COFFEE CARAFE, CHEMEX FILTERS (unbleached in circle shape) and terrific roasted beans....Where's the grinder...YIKES! no grinder! It's elsewhere...WHAT TO DO till I get my grinder in hand...Well I went to the supermarket and picked up a LARGE/huge can of inexpensive coffee. CHASE and SANBORN.... I had to make something in the new pot....right???? This was the finest cup of joe. It tasted so fine with a bit of sugar. No fines or bitterness in the mug. I used the "DOT" (raised bump) on the carafe to make 24 ounce of splendid coffee. I measured out 5 cups of coffee for a 4 cup pot. I believe the filter is ALL IMPORTANT! The carafe is easy to handle. I fill the carafe with cold tap water (to the dot which is ~ 24 ounce) dot is a measurement indicator on the carafe. Putting the cold water from carafe, I put on an electric (short spout)CUISINART kettle to boil I pour HOT tap water, into the carafe ~145 degF to pre-warm I pour hot tap water into my 24 ounce OXO thermos cup to pre-warm I put the CHEMEX filter in the top of carafe I put 5 cups, measured, of coffee into the filter When water is boiled I pour kettle water onto grounds to cover the grounds I wait for the water to completely drain; thus allowing the grinds to "BLOOM" After water is through the grinds and the bubbles stop (within seconds) I continue to pour the remainder of the boiled water on the grounds...SLOWLY... After kettle is EMPTY AND ALL THE WATER IS THROUGH THE GROUNDS Remove the grounds filled filter and fill the pre-warmed OXO thermos mug with coffee A bit of sugar and the nicest cup o joe is waiting for me! NO OIL SHEEN, NO BITTERNESS Easily replicated coffee each time. To clean... I swirl HOT water in the carafe and put it aside till the morrow. DAMN! I LOVE this drip maker... I got the 8 cup carafe I am awaiting my CAPRESSO grinder to show up at my door I really don't need it though....SURPRISE!!!! to me "

Using it for the Krups Moka Brew
Style: Square
I don't have a Chemex brewer, but I do use a Krups Moka Brew. The filters for the Krups are expensive and difficult to find, so I tested these Chemex filters to see how they would perform. A square Chemex filter is 12" x 12", which means that I can cut out 9 Krups-sized filters out of each one. A box of 100 Krups filters costs 7 to 10 bucks. For about the same price, I get 900 from the Chemex. The Chemex filters are also thicker than the Krups filters - I'd say about 20%. I've been using the Krups Moka Brew for several years and love the coffee it makes (and you can even do an abbreviated brew to make something that resembles espresso). I ran several back-to-back brews comparing the performance of the Krups filter vs. the Chemex filter on my Moka Brew. I used 20 grams of the same home roasted coffee with 500mL of water for each brew, and a Capresso Infinity grinder. Skip to the conclusion if you just want the results. A) Krups filter. I used only one filter and tamped down with a moderate amount of force. The beans were ground on the finest "fine" setting (#5). This is how I usually do it on the Moka brew. From the time the water hits the coffee, it took 3m50s for the brewing to complete. Initially there was the characteristic delicious looking thick drip with the dense crema - it looks close to espresso, with a bit of the mouse tailing (sometimes I stop the brew at about 30 seconds and just drink that. It's close to espresso and very delicious). The complete brew had a lot of body with robust flavor, like a great americano. B) One Chemex filter. I ground the beans and tamped them like with the Krups filter. I was shocked to see how fast the water came through. It was a waterfall compared to the rich stream from the Krups filter. The brewing time was only 2m20s. There was none of that rich dense crema at the initial stages and the resulting coffee tasted more like a drip brew. It had thinner body vs the Krups filter, and the flavor was cleaner. It's still a decent cup of coffee, but I was surprised at the amount of difference the filter made. C) Two Chemex filters. I decided to use two filters, one on top and one on the bottom. I also changed the grind setting to 3 notches finer (#2). I tamped it pretty hard. The brewtime for this was comparable to using one Krups filter - 3m45s. However, the brew still looked different vs the Krups. While it was no longer the waterfall that it was with just one Chemex filter, and the drip rate was similar to that of the Krups filter, the characteristics were still very different. Mainly, it still lacked that rich looking initial brew stage that you get with the Krups filter. The body was thicker vs using one filter, but still slightly thinner than with the Krups filter. Conclusion: The Krups filter makes a huge difference versus using the Chemex filter. Despite being thicker, the Chemex filter results in a faster brew with less body and a cleaner cup profile. The Chemex results are still good, but closer to a normal drip brew, rather than a moka/americano quality one gets with a Krups filter. I recommend using a finer grind with the Chemex filter, and using two (or more?) filters - at least when brewing less than a full pot. The Chemex filters will still be cheaper since they're roughly 1/7 the price of a Krups filter. I can't say that one result is better than the other - it's a matter of preference. I prefer a fuller body (and an occasional "espresso" from the Moka brew), so I'll still get the Krups filters despite the high price. However, the Chemex filter is an option when the Krups filters are unavailable (as often happens). The Chemex might also result in better coffee for beans that are brighter and lightly roasted - worth testing.
