Reusable Chemex Filters

Just so you know, if you click on a product on and decide to buy it, we may earn a small commission.

If you’re the proud owner of a Chemex coffee maker and looking for ways to live more sustainably, we’ve got you covered. Even though you coffee fans want that guaranteed smooth, low acid coffee flavor that comes from the pour-over brew method, you’re worried about your impact on the environment. We understand.

It may seem like a big task, but reducing waste doesn’t have to be difficult or inconvenient. One easy way you can do this with your Chemex is to stop using disposable paper filters and switch to reusable ones. 

We all want to do the little things we can to help the environment. While you can choose to compost your traditional paper filters, many people don’t have the time or the space to handle composting filter paper. That’s why reusable filters are the best option for people looking to do their part quickly and easily.  

Not only will buying a reusable coffee filter help the planet, but it will save you money in the long run. 

In this article, we’re going to break down the different options for reusable filters for your Chemex and provide an example of each, so you’ll know exactly which one is right for you. 

Filter Types

While Chemex has advanced the coffee-making industry greatly since they showed up on the scene in the 1940s with the family-invented Chemex coffee maker, they have yet to put out a reusable filter for their products. Chemex users must continually order more disposable filters or look elsewhere for one that will last. 

Fortunately, several types of reusable filters are compatible with Chemex: Metal, cotton, and hemp. Each filter type comes with its advantages and disadvantages. Some are harder to clean, while others do a better job of keeping out sediment. 

Metal Filters

Metal filters are the most common reusable filters. While the design varies by product, many are double-walled food-grade stainless steel with stainless steel mesh on the inside to provide the best flavor immersion with the fewest loose coffee grounds. 


  • They make a stronger cup of coffee than paper because they’re non-absorbent and don’t soak up the oils and flavors of the grind. 
  • They’re durable and long-lasting.


  • They can be difficult to clean 
  • They don’t always keep out all of the sediment 

Best Metal Filter Option: Barista Warrior Gold Conical Filter

These metal gold-tone coffee filters are dishwasher safe for simple, quick cleaning and will last for years. Just rinse it under warm water for a quick clean. They remove more of the bitterness from coffee, and they can also be used in some pour-over coffee makers and coffee drippers. The manufacturers of this stainless steel filter even offer a six-month money-back guarantee. If metal is the right type of reusable filter for you, be sure to check out Barista Warrior. 

Cotton Filters

A Chemex coffee filter made of cotton, often known as a Chemex coffee sock, is another eco-friendly compromise between paper and metal filters. These natural filters may require a finer grind than others to do their best, but they can still work with any size grounds and help give a rich texture to coffee. 

The best thing about cotton filters is making hot or cold brew cups of coffee with them. You can learn more about this (and the other benefits of cotton filters) here. 


  • They remove more coffee sediment than a metal filter
  • They retain more oils and flavors from the coffee beans than a paper filter  
  • They’re affordable 


  • They have to be hand cleaned with hot water and dried to remove the built-up coffee oils
  • They aren’t as durable as metal filters 
  • They’re not bacteria and mildew resistant, so you must wash before and after every use

Best Cotton Filter Option: Sentir Cubano Cloth Coffee Strainer

These white filters are unique because of their steel handles that allow for easy insertion and removal. They’re made out of sturdy flannel material and will last years with proper care. These filters will make a good, strong cup of coffee every time. 

Hemp Filters 

While cotton and metal filters are a great alternative, there is no eco-friendlier option than hemp. Not only are they better for the environment than cotton, but they also last longer and don’t develop bacteria as easily. 


  • They filter out sediment without absorbing the coffee oils
  • They’re naturally resistant to mildew and bacteria 
  • They’re more durable than cotton 


  • You have to rinse and dry them after every use 

Best Hemp Filter Option: Bolio Organic Hemp Cone Filters

These hemp filters do the job just as well as paper without the waste while putting out a full, delicious coffee flavor. This company also offers a money-back guarantee on their product if this hemp filter isn’t for you. 


Just because coffee drinkers switch from disposable filters, it doesn’t mean they have to compromise on ease and the delicious taste of coffee. There is a Chemex reusable coffee filter for every type of coffee lover. 

No matter your personal preference, whether you want to toss your filter into the dishwasher on your way out, or you don’t mind taking the time to hand wash it, there is one to suit your needs. Take this into consideration before buying one for your Chemex. 

No matter which reusable filter you choose, creating less waste while enjoying the coffee experience always pays off. 

Happy Caffeinating!
