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 *by on Reviewed in the United States February 21, 2012* 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 boilI pour HOT tap water, into the carafe ~145 degF to pre-warmI pour hot tap water into my 24 ounce OXO thermos cup to pre-warmI put the CHEMEX filter in the top of carafeI put 5 cups, measured, of coffee into the filterWhen water is boiled I pour kettle water onto grounds to cover the groundsI 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 GROUNDSRemove the grounds filled filter and fill the pre-warmed OXO thermos mug with coffeeA bit of sugar and the nicest cup o joe is waiting for me!NO OIL SHEEN, NO BITTERNESSEasily 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 carafeI am awaiting my CAPRESSO grinder to show up at my doorI really don't need it though....SURPRISE!!!! to me " ### ⭐⭐⭐⭐⭐ Great Filters! Box of 100 can last for Years! *by on Reviewed in the United States October 30, 2017* These coffee filters are top notch, and there's a hidden bonus that I'll tell you about. First, my process:1) Use ceramic burr grinder to grind beans into a fine grind, about the consistency of powdered sugar.2) Add grinds to filter (in a chemex decanter, obviously) and then pour just enough boiling water on the grinds to soak them. This is recommended by chemex as well if you read the insert they give you.3) After about 30-60 sec I just pure water in until the level is about 2/3 up the edge of the decanter and let it brew. Works great.So using this method, and after having tried various coarser grind settings, this has proven to work the best with all different types of coffee beans. I have also tried using the metal chemex filters here and they are total junk. They clog if you use anything other than coarse grinds, but the coarse grinds don't let you get the best flavor.Now here is the tip. These chemex paper filters are REUSABLE. Yes, here's how:1) Right after you finish brewing coffee just rinse away the grinds gently under the tap.2) Don't crumple the filter or try to wring it dry. After you rinse it, and it's still wet, fold it back into its original shape as best you can and let it dry in your dish rack.3) One filter will easily last 10 brews or more. Flavor will not be compromised. When you notice the fibers of the filter start to get stringy and fuzzy, that's when you swap over to a fresh one.There is no reason to brew once and then throw away the filter. It is VERY HIGH QUALITY PAPER and in my opinion, using it multiple times actually improves the flavor. I've gotten over 20 brews from one filter and on the 20th time the chemex still did a better job than one of those cheapo paper filters they sell in most supermarkets. ## Frequently Bought Together - Chemex Bonded Filter - Square - 100 ct - Exclusive Packaging - Chemex Pour-Over Glass Coffeemaker - Classic Series - 8-Cup - Exclusive Packaging --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/1488225-chemex-coffee-filters-20-30-thicker-made-in-usa-compostable](https://www.desertcart.us/products/1488225-chemex-coffee-filters-20-30-thicker-made-in-usa-compostable) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-11*
