What Is a Chemex Filter?
Coffee lovers are no strangers to the Chemex filter because it is one of the coffee filters that bring great convenience to the brewing process. Like its name, this filter is manufactured by Chemex, a famous brand with a long history of establishment in the US.
This filter meets the filtering coffee grounds process requirements and supports making excellent coffee quality.
The Chemex filter provides the best convenience for many people by cutting down the cleaning time in half compared to the traditional counterparts. As this product is disposable, the only remaining appliance to clean is your carafe.
How Is Chemex Filter Structure/Materials?
The Chemex filter is made of thick laboratory-grade paper with a 20 to 30% thickness than normal paper.
It allows you to prevent harmful elements in the coffee beans from seeping down and settling in your cup. Your beverage is free of unhealthy bitter elements and other impurities, thanks to Chemex’s product.
With a smart design, you will have filter sides with different layers when using a Chemex filter.
In particular, the most important is the 3-layer side because it helps stabilize the filter when getting wet. That minimizes the risk of filter collapse, and you can safely pour hot water into your carafe.
How Much Does Chemex Filter Cost?
Chemex filter price is higher than its counterparts. There is a simple reason for that if you look at its structure. The manufacturer has used many layers to form a Chemex filter, causing a higher production cost than conventional filter papers.
Moreover, that thickness is a big advantage of the Chemex filter, making it comfortable to fold and firm to store coffee ground during the brewing process.
Why Is It Not Advisable To Reuse Chemex Filters?
You can reuse a Chemex filter, but the result the second time around will not be efficient. Let’s examine why reusing the Chemex filter does not bring the desired coffee filter effect.
First, when releasing the Chemex filter, the manufacturer designed it to have the highest efficiency for only one time. Chemex filters aren’t meant to be rinsed. That is also why a box of Chemex filters has up to 100 pieces corresponding to 100 uses.
The second reason is its practical effectiveness. After one use, the tiny particles from the coffee powder will stick in the Chemex filter. They can be coffee oil, coffee grounds, or impurities.
Even if you try to empty the used coffee powder and clean the surface of the Chemex filter, these particles remain.
And worse, as you use it for the second time, the remnants will settle more, causing over-extraction. It will slow down the filtering process and not be able to perform at its best.
All coffee lovers recommend not reusing Chemex filters, for they want the best cup of coffee. Poor-quality coffee will not bring you a great experience. Meanwhile, using a new Chemex filter for each brew is the best way to ensure quality.
Above are all the reasons not to reuse the Chemex filter. It is advisable to use a new Chemex filter in every new brewing for the best performance and efficiency.

Reusable alternatives are filters that you can use many times. You will not throw it away after one use, and all you need is to clean it and let it dry.
The CoffeeSock Reusable Filter
There are many ways to filter coffee, and one of them is to use a coffee sock. You can reuse Coffee socks many times. The maintenance is straightforward: wash it with water and detergent, then let it dry to ensure it is always in the best condition before starting the second filtration.
For extra cleaning, it is necessary to soak the filter in boiling water for a few minutes. The advice is to buy two for use in turn while waiting to dry.
Normally, CoffeeSock is made from organic fabric to ensure safety when used. Its design is quite diverse with 6/8/10/13-cup types, but the best-selling option is 3-cup.
You won’t have to worry about CoffeeSock affecting the flavor of your coffee. With 90% cellulose, it is guaranteed to be odorless and tasteless, while the paper is 40-50% cellulose. Therefore, reusing CoffeeSock is undoubtedly better than reusing Chemex filters.
Metal Reusable Filter
The special feature of this filter is that it always has stainless steel meshes. Some special editions even use titanium-plated gold for its great appearance.
However, because of the characteristics of metal, this filter type cannot completely refine the oil and impurities in the coffee. It means the filtering efficiency of the metal model is not as high as paper or coffee socks.
Although filtration efficiency is not high, it can produce acidity or bitterness, a taste that many people love.
Metal filters are quite difficult to clean because the coffee ground will stick to the holes in the mesh. So, when washing, you will need an extra brush.
However, people still love to use a metal filter as it is more durable than others. They can use the metal one for years without changing the new one.
