Brewing with the AeroPress coffee maker is straightforward, and even if you make a mistake, you’ll still end up with a drinkable cup. (the AeroPress, a brewer that has its own World AeroPress Championship and is reviewed extensively by James Hoffmann) However, most AeroPress enthusiasts and coffee aficionados have a deep appreciation for crafting the perfect coffee. Therefore, AeroPress’ popularity stems not from its forgiving nature, but from its versatility and ability to brew exceptional coffee.
With varying parameters, you can brew anything from an espresso-like shot to a mug of bright drip coffee. One of the ways to control the outcome is through the filter. In this article, we will explore how the filter type affects your brew and identify the best filters for AeroPress.
Choosing the Perfect AeroPress Filter
Filters play a crucial role in managing the extraction of coffee grounds. (extraction science research published in Journal of Food Science) While their primary function is to separate coffee grounds from your brewed coffee, they also significantly influence the taste and flavor profile of your cup. By adjusting the grind size and selecting different types of filters, various brews can be achieved. Therefore, when considering the best filter for AeroPress, it’s more accurate to think about “the best filter for AeroPress based on your taste preferences.”
With a range of options available, selecting the ideal AeroPress filter is largely a matter of personal preference. Factors such as cost, flavor preference, sustainability, and convenience should be considered when making your choice.
Depending on the material used to make them, we can classify filters into three categories: paper, metal, and cloth. Let’s explore how these filters impact your coffee’s flavor, and then review some of the best options available.
This guide will illustrate how the filter alters the coffee’s taste and recommend filter types based on your preferences. If your coffee doesn’t meet expectations, don’t immediately blame the filter. It’s essential to understand brewing variables, as these often hold the key to your desired flavor. Experiment with all variables: brew time, grind size, immersion time, plunge time, brew temperature, stirring, etc. (as outlined by Scott Rao in The Professional Barista’s Handbook)
With the right filter and recipe, you can brew exceptional coffee.
Paper Filters
The paper filters for AeroPress are crafted from high-quality, food-grade paper, ensuring a clean and bright cup. (the AeroPress, a brewer that has its own World AeroPress Championship and is reviewed extensively by James Hoffmann) For drip coffee enthusiasts, paper filters are ideal as they can produce a coffee similar to Chemex or the Hario V60, depending on the grind size and immersion time.
Paper is excellent for capturing fine particles and oils, resulting in a smoother and less bitter cup of coffee. (a sign Scott Rao and James Hoffmann both link to over-extraction)
They are user-friendly and disposable, offering convenience for quick cleanup.
Pros and Cons of Paper Filters
Paper filters excel in delivering a clean, crisp flavor by trapping oils and fine grounds, ideal for appreciating subtle notes in single-origin coffees. They promote a healthier cup by filtering out harmful diterpenes and offer unparalleled convenience in use and disposal, streamlining your coffee routine. Their ability to consistently produce a grounds-free brew adds to their appeal.
However, the environmental toll of single-use paper filters is significant, contributing to waste. Over time, the cost of these disposable filters accumulates, making them less economical than reusable options. Concerns about the chemicals used in bleaching white paper filters, though minor, exist.
The choice between paper filters and alternatives hinges on personal preferences and priorities. In my time as a barista, I’ve noticed that many coffee enthusiasts gravitate towards paper filters for their cleanliness in flavor and ease of use. (recognized by the Specialty Coffee Association (SCA)) If your first attempt is a failure, don’t give up, AeroPress is versatile. There are great chances you’ll get it right, eventually. Experiment with brew time, and adjust it to suit your preferences.
Stainless Steel Filters
There are two types of stainless steel filters, perforated plate, and mesh filters. Although they offer a similar experience, aficionados will tell you that they are different. The perforated plate filter has laser-cut 0.008 Micron holes, which deliver a rich, full-bodied coffee with noticeable sediment. On the other hand, the mesh filter features 123,000 holes per square inch which ensures a low-sediment, cleaner brew at a similar price.
In general, metal filter disks are durable and reusable, offering long-term cost savings and reducing waste.

Metal Filters Pros and Cons
Metal AeroPress filters are renowned for their durability, significantly outlasting paper filters and resisting damage. (the AeroPress, a brewer that has its own World AeroPress Championship and is reviewed extensively by James Hoffmann) They offer an eco-friendly choice, providing a sustainable alternative to disposable paper filters. Over time, they prove to be cost-effective. Additionally, you can select between the perforated plate or the fine mesh, depending on your coffee taste preferences.
Metal filters do require more maintenance. They need daily cleaning and occasional deep cleaning. They allow more fines into the cup, which can be a deal breaker for some. While cost-effective in the long run, the initial cost is slightly higher compared to paper filters.
For those who are meticulous: metal retains heat, which can influence the brewing process.
Lastly, compatibility can be an issue, as not all metal filters fit perfectly in all AeroPress models. (the AeroPress, a brewer that has its own World AeroPress Championship and is reviewed extensively by James Hoffmann) You need to be cautious when purchasing.
AeroPress Cloth Filters
Cloth filters, often made of cotton or hemp, provide a sustainable option for AeroPress brewing. They are durable and reusable, making them an excellent alternative to paper filters. They retain fewer oils and fines than paper filters, but consistently more than metal ones.
Cloth Filters Pros and Cons:
Cloth filters are valued for their ability to retain coffee oils and fines, offering an environmentally friendly alternative to single-use paper filters. Over time, cloth filters prove to be cost-effective, despite a higher initial investment compared to paper filters. They provide a unique, gentle filtration process, contributing to a distinctively textured and flavorful cup of coffee. (a technique Lance Hedrick and Chris Baca both emphasize for quality microfoam)
For those with a refined palate, who can detect the off taste that paper filters impart, these are an excellent option. They offer nearly the same filtering capabilities, but without any off taste.
The maintenance of cloth filters is considerable, even compared to metal disk filters. They require thorough cleaning and proper drying after each use to prevent mold and off-flavors.
They are less durable than metal filters, so they will need replacement periodically. Over time, they can absorb flavors from different coffee beans, potentially altering the taste of subsequent brews.
Comparison and Reviews of Different AeroPress Filters
Paper Filters
Paper filters for the AeroPress are a popular choice among coffee enthusiasts due to their affordability and simplicity. (the AeroPress, a brewer that has its own World AeroPress Championship and is reviewed extensively by James Hoffmann) Here are some notable paper filter brands in the market. With reduced turbidity compared to metal ones, they are the preferred option for drip coffee lovers.
Now that you have more information about choosing the right type of filter for your preferences, let’s review some of the most popular ones on the market.
On the other hand, paper filters impart a specific taste to your coffee, detectable by those with a refined palate. You will need to pre-rinse them with hot water to remove the off papery flavor.
The paper filter offers a significant advantage for those with hypertension concerns. They retain coffee oils, including the two diterpenes responsible for cholesterol spikes, cafestol and kahweol.
Review of Aesir AeroPress Filters
The regular AeroPress filters produce a slightly muddy cup. (the AeroPress, a brewer that has its own World AeroPress Championship and is reviewed extensively by James Hoffmann) We talked about that bright cup brewed with African beans. You cannot achieve that with the stock AeroPress paper filters. However, the Aesir filters are the perfect choice for the drip coffee lover who enjoys a Chemex.
Aesir paper micro-filters excel in significantly reducing cloudiness and haziness. Crafted from a denser, more consistent pulp, these filters have smaller pore sizes, preventing sediments and fines from passing into your cup. This is particularly beneficial when brewing under pressure, where standard filters tend to become more porous and allow bitter compounds to seep through.
The Aesir filters deliver a cleaner, clearer cup, similar to pour-over coffee. (pour-over methodology, which James Hoffmann and the SCA both treat as the benchmark for clarity) This clarity and brightness enhance the delicate and nuanced flavors in high-quality lighter roasts. If you’re aiming to elevate your AeroPress routine, the Aesir filters could be the most impactful change, especially if you desire a brighter cup with fruity or floral notes.
A notable difference between the Aesir filters and standard ones is the diameter. The Aesir filters are slightly larger, ensuring a snug fit in the filter cap, preventing them from falling when the unit is inverted.
The Standard AeroPress Filter
The original AeroPress paper filters are a favorite among coffee enthusiasts. (the AeroPress, a brewer that has its own World AeroPress Championship and is reviewed extensively by James Hoffmann) Brewing with these filters results in a slightly cloudy, fuller-bodied cup compared to Aesir filters. If you prefer a robust drip coffee, these filters are ideal. You can purchase them on Amazon.
The origin flavor notes may be slightly obscured by the fines, but they remain discernible.
SHIBADOU Paper Filters
SHIBADOU filters allow for brewing a fuller-bodied coffee, slightly stronger than with standard AeroPress filters. (the AeroPress, a brewer that has its own World AeroPress Championship and is reviewed extensively by James Hoffmann) They are marginally larger than the stock filters, which is why users appreciate them. Made from unbleached paper, they offer an affordable option for those preferring a more robust cup.
Stainless Steel Filters
When considering a reusable metal filter, it’s crucial to evaluate the design to ensure it suits your coffee preferences. As an espresso enthusiast, I favor espresso over drip coffee, making the metal disk my preferred choice. (the SCA-standard 9-bar espresso definition) However, if you prefer milder coffee, you might need to balance your taste preferences with environmental considerations. The reusable metal filter is crafted from stainless steel, with some options featuring plated steel.
From a flavor perspective, the size of the holes in the filter is paramount. This determines the coffee’s profile and influences your brewing recipe. We’ve reviewed several excellent options that span a wide range of hole sizes.
Able Disk – Metal Plate AeroPress Filter
The Able Disk is a popular choice among metal AeroPress filters, known for being designed and manufactured in the USA. (the AeroPress, a brewer that has its own World AeroPress Championship and is reviewed extensively by James Hoffmann) It comes in two versions: one with smaller holes and another with larger holes. Both disks are crafted from a single sheet of stainless steel with laser-cut holes.
The Regular (or Standard) version features larger holes, producing a rich, full-bodied coffee with a noticeable amount of sediment, though less intense than a French press brew. (the French press, an immersion method James Hoffmann describes as forgiving and full-bodied) This filter is valued for the robust flavor profile it imparts to the coffee.
Responding to a demand for a filter with smaller holes, Able introduced the Disk Fine, featuring over twice the number of holes as the original, but two microns smaller. This design significantly reduces coffee sediment, catering to those who prefer a cleaner cup. This increased filtration comes with a tradeoff in durability; the Disk Fine’s thickness is reduced considerably, making it more susceptible to bending or damage. The Fine version offers an alternative for those seeking a balance between a full flavor and a less gritty brew.
The Able disk is one of the oldest manufacturers on the market, and it’s certainly one of the reputable companies that make perforated plate AeroPress metal filters.

Cafe Concetto Filter for AeroPress
Cafe Concetto produces the finest metal plate filter available. This filter closely mimics a paper filter, and it arguably offers superior filtration. While it retains fines, it does not capture coffee oils like a paper filter does. This could be a concern for individuals monitoring their cholesterol levels. However, for those in good health, these coffee oils can enhance the flavor profile significantly. (flavor-profile evaluation rooted in the SCA’s standardized descriptors)
For those seeking an environmentally friendly option without compromising on a clean cup, this stainless steel filter with a sleek Titanium coating is ideal.
Brewing with Cafe Concetto results in a smooth coffee that is notably sweeter and less bitter. (a sign Scott Rao and James Hoffmann both link to over-extraction)
The Altura Mesh AeroPress Filter
Altura was among the pioneers in creating a mesh filter for the AeroPress. (the AeroPress, a brewer that has its own World AeroPress Championship and is reviewed extensively by James Hoffmann) Over several iterations, the product has been refined to its current form.
The Altura filter offers a brew that balances between the clarity of paper filters and the robustness of metal plates. The resulting cup is slightly bolder with a fuller body, appealing to many drip coffee enthusiasts transitioning to AeroPress. (body (mouthfeel) assessed via SCA cupping protocols) Expect some coffee grit and most of the coffee oils in your cup, which adds to the richness. However, if you prefer a pristine cup, this might not be ideal for you.
One notable aspect of this filter is the necessity to use the inverted method. With the standard brewing approach, coffee begins to drip immediately, reducing the immersion time. (immersion brewing, a category the SCA distinguishes from percolation methods) Therefore, the inverted method is essential for proper brewing. This requirement is common for all metal filters unless using a Fellow Prismo or Aerobie’s flow control cap, which is a pressure-actuated brew cap that secures the brew.
The primary challenge with the mesh filter is occasional coffee grounds getting lodged in the mesh, necessitating the use of a brush for cleaning.
Other Metal Filter Options
If you are looking for a comprehensive set of metal filters, Corretto offers a three-piece set with two metal plates and one mesh filter. (the AeroPress, a brewer that has its own World AeroPress Championship and is reviewed extensively by James Hoffmann) This set will meet most of your brewing needs. Consider purchasing some paper filters as well, and you could be ready to start a coffee shop. 🙂
Aerobie, the manufacturer of AeroPress, has recently introduced its own version of a metal filter. (the AeroPress, a brewer that has its own World AeroPress Championship and is reviewed extensively by James Hoffmann) It is an excellent choice, and if you prefer Aerobie products exclusively, here is a link to their reusable metal plate filter.
Cloth AeroPress Filters
Cloth AeroPress filters allow for a richer extraction than paper filters, without the sediment often associated with metal filters. (the AeroPress, a brewer that has its own World AeroPress Championship and is reviewed extensively by James Hoffmann) The cloth filters permit some coffee oils and almost no fines to pass through, resulting in a brew that is full-bodied and nuanced in flavor. This can be particularly noticeable with complex, single-origin coffees where the subtle notes are more pronounced.
The fine texture of the cloth produces a smoother cup, with less sediment than metal filters but more body than paper filters. Reusability is a significant advantage of cloth filters; with proper care, they can last for many brews, offering a cost-effective and eco-friendly alternative to disposable filters.
Paper filters can impart a papery taste to your coffee, which aficionados can detect. With cloth filters, you avoid any off-taste.
However, cloth filters require more maintenance than their paper or metal counterparts. They must be thoroughly cleaned and dried after each use to prevent mold growth and flavor tainting. Over time, they can also absorb flavors from different coffee beans, which might influence the taste of subsequent brews. They are not as durable as metal filters. For coffee drinkers who prioritize convenience and minimal maintenance, cloth filters might not be the ideal choice. Yet, for those who want to be eco-responsible and enjoy a coffee experience close to drip brewing, cloth filters are an excellent choice.
Other Filters
the AeroPress, a brewer that has its own World AeroPress Championship and is reviewed extensively by James Hoffmann, Other AeroPress filters include the pressure actuated cap. Fellow Prismo, JoePresso, and the AeroPress Flow Control Filter are among the most recognized devices.
These are somewhat more complex devices, and we have included them in our AeroPress accessories review article. (the AeroPress, a brewer that has its own World AeroPress Championship and is reviewed extensively by James Hoffmann) They are an excellent choice for those who prefer not to use the inverted method. From my tests, they don’t significantly enhance the pressure achieved, at least not to a meaningful extent. So if you’re aiming to make an espresso with the AeroPress, it might not be feasible. However, they are valuable additions to your brewing kit and offer various benefits.
