About this item

  • Step 1: Fold the CHEMEX filter in half. Then fold in half again, bringing the two corners together. Place your finger between the 3rd and 4th layer and open into a funnel.
  • Step 2: Place the funnel in the top portion of the CHEMEX coffeemaker, with 3 layers on the groove side. The groove is an air vent (and also the pouring spout) and allows air to escape from the lower portion of the coffeemaker.
  • Step 3: Put coffee in the filter paper cone. Use one heaping tablespoon per cup of coffee (adjust to personal taste if needed after first brew). Refer to brewing instructions for remaining steps.
  • THICKER: 20-30% thicker than the competition, specialty fiber filter design keep bitter elements, oils, and grounds in their place (and out of your cup)
  • Fits all CHEMEX Coffeemakers except CM-1, CM-1C, CM-1GH

Customers find these coffee filters work well with Chemex glass makers, effectively filtering out fine grounds and oils while bringing out coffee flavors and removing bitterness.

★★★★★

Works great! Better than regular cone filters.

T-MozJanuary 4, 2026

I'm not new to making pour-over coffee, but I am new to using a "fancy" filter like these Chemex filters. They did a really good job. The coffee tastes better than with the cone-filter brand I was using before, and the water actually goes through the grounds more consistently too. With the previous cone filters, the water seemed to slow way down by the time I had poured half the water in. Not so with the Chemex filters - the water flows pretty consistently from start to finish. Read more

Great filters

AndreaJuly 9, 2025

These Chemex natural coffee filters are the only ones I use now. They fit perfectly in my Chemex and never tear or collapse. I love that they’re unbleached, so I don’t have to worry about any extra chemicals in my coffee. They filter out the fine grounds and oils really well, leaving my coffee clear, smooth, and rich without any bitterness. I also notice they’re strong enough to hold even when I make a larger batch. Definitely worth it if you want to get the cleanest taste from your beans. Highly recommend to any Chemex user. Read more

Before being a Barista required a Master's Degree.

JernDecember 6, 2017

I prefer the unbleached. If you have a Chemex this is what you want, don't mess around with imposters and makeshift solutions the filter is key. All the reusable mesh ones have failed me, despite wanting to like them. I've tried it all... Industrial Automatics like the Burr, fancy home models like the Ninja or Braun, French Press, Keurigs, Nespresso, cold brew, and on and on. At the end of the day the Chemex pour-over is my go-to, all-time heavyweight coffee making champion and it's dead simple, cheap and quick. To qualify: I'm not a uppity coffee connoisseur. I've never been a barista. I don't have really staunch opinions on grind levels, temperatures and astrological charting for my morning coffee. I just want it to be good and the way I want it. Some helpful hints / important points for those going down this road: 1. First, rinse the filter (esp. for the unbleached). A variety of reasons exist but just do it and we'll leave it at that. 2. The folded side (thickest) goes against the side with the spout / pouring channel. This has less to do with the quality of the coffee so much as it has to do with not making a mess. It's not a recommendation, it's the directions on the side of the box. 3. Get the other stuff A kettle like this: Pour Over Coffee Kettle with BUILT-IN THERMOMETER - Large 1.2L - Gooseneck Drip Coffee Kettle and Stainless Steel Stovetop Tea Pot with a temperature gauge and the gooseneck spout. Using a regular tea kettle is not smart here. Any kind of grinder will do. The hand grinders are just annoying novelty products unless you live in the forest and require an off-the-grid option. After a week or two of dealing with one I think you will regret it. This one is cheap and effective: KRUPS F203 Electric Spice and Coffee Grinder with Stainless Steel Blades, 3-Ounce, Black But there's varying levels of options and design sensibilities out there for coffee grinders if you really want to complicate things. Then of course whatever Chemex model you like. I went for the Chemex 10-Cup Classic Series Glass Coffee Maker , because why feel limited? Of course, coffee is required so grab your favorite. I've been pretty loyal to this brand for a while: Heavenly Hazelnut, 2lb, Whole Bean Coffee, Light Roast, Direct Trade, 100% USDA Organic Certified The overpriced and overrated boutique stuff isn't my style. 4. If you have plants or a garden you can easily just take your grounds along with the filter and compost it or simply mix it with garden soil. This is way better than the Nespresso / K-Cup situation that I feel is just gross and unnecessarily wasteful. If you want to pursue that option go for a little caddy so you can bring the filter outside to your bin without making a mess. This one is nicely priced and will do just fine: Tierra Garden GP118 Odor-Free Compost Caddy, Mini 5. Don't let snooty people tell you how to make or enjoy your coffee. Look around and experiment with some temperature / grind levels. Throw some cheapo non-dairy powdered creamer in there if you feel the urge. At the end of the day, it's about you and your need to feel alert. 6. Try to stick with the Chemex branded products if you can- they did it first, and they thought it through. All this copy cat stuff just amounts to money-grabs. There's nothing to improve upon! It's a glorified funnel! I've tried every coffee making apparatus under the sun into the far reaches of the "stupid expensive" category range and I always come back to this simple fella and my 10-Cup (I believe the 8-Cup Chemex is on the filter box, the 10 is just a tad larger) which I guess is around $50 now. For a comparatively small investment you can kill the coffee game for many years to come. My Chemex 10-Cup is about a decade old and it still looks new. Once you do it like this you can never go back to the automatics. Read more

Great Product! Gamer Approved!

xShelp_-June 28, 2025

Classic Chemex filters, thick, durable, and designed to deliver that clean, crisp cup every time. The natural version adds a subtle earthy note and holds up without tearing or clogging. Perfect fit for the Chemex brewer and essential if you’re after consistent clarity and smooth flavor. If you're considering getting into Chemex brewing, I’d recommend sticking with the paper filters over the reusable ones, better taste, easier cleanup, and more reliable results. Read more

Zen coffee filter

PavotOctober 26, 2025

Great way to start the morning! I honestly wasn’t sure, when I first used them. I quickly learned to fold the filter, origami style, like a nun’s habit. It is a nice zen moment. These really make a delightful cup of coffee. I will use these always! Read more

Chemex Natural Filters = Healthy filters

Julianna SNovember 3, 2024

Chemex natural filters are very easy to use and safe for coffee making. Once you’ve done it a few times, you’ve got it! Step 1: Separate 1 layer out from the pre-folded filter and place the remaining 3 folded layer on the spout of your Chemex. It’s especially important to place the 3-sided fold against the spout as it acts like a vent. Step 2: As you wait for your water to heat up, pour warm/very warm water through your filter into your Chemex about 1/2 way up. This warms up your carafe prior to brewing coffee and also eliminates any paper taste from the filter. Step 3: When water for coffee is heated, pour out the warm water from your Chemex. (Yes, the filter will be wet.) Step 4: Place the wet filter back into your Chemex and add your desired coffee grinds. Step 5: Pour a small amount of the heated water into the grinds and allow coffee to “bloom” for 30 seconds as it initially brews (it really makes a difference!) Step 6: Continue to slowly pour over the remainder of your water into the Chemex to brew your coffee. Be patient. It’s worth it! Read more
