AeroPress filters come in three basic flavours: the tiny round paper micro-filters that ship in the box, reusable metal discs (stainless or fine-etched), and the fine-mesh cloth option. The choice is small but it genuinely changes your coffee. Paper gives the cleanest, brightest cup; metal lets the oils through for more body and a heavier mouthfeel; cloth sits somewhere in between. This guide walks through every type, how they fit the different AeroPress models, and a clear verdict on which to buy. For the actual brewing recipe, see our AeroPress brewing guide — here we focus only on the filters.
What AeroPress filters do and why they matter
The filter is the last thing your coffee passes through before it hits the cup, so it has an outsized effect on taste and texture. It controls two things: how much of the coffee's natural oils reach you, and how much fine sediment (called "fines") gets through. More oils and fines mean a fuller, heavier body. Fewer of them mean a cleaner, more transparent cup where delicate flavours stand out.
That single trade-off — body versus clarity — is the heart of every filter decision. There is no universally "best" filter, only the one that matches the cup you want and the beans you brew. Light and medium roasts with fruity, floral notes usually shine through paper. Darker, chocolatey roasts and anyone who likes a robust, almost espresso-ish texture tend to prefer metal.
AeroPress paper filters: the clean-cup default
The standard aeropress paper filters are slim discs roughly 2.5 inches (about 64 mm) across, made from thin, tightly woven, food-safe paper. A box typically holds around 350 of them, which lasts most people many months. They are the filter the AeroPress was designed around, and for good reason.
Paper absorbs much of the coffee's oil and traps nearly all the fines. The result is a bright, clean, almost tea-like clarity — the kind of cup that highlights a coffee's acidity and aroma without any grit at the bottom. If you drink single-origin coffees and want to taste what the roaster intended, paper is hard to beat.
White vs natural (brown) paper
Paper micro-filters come in two looks. White filters are chlorine-free bleached paper; natural (unbleached) filters are tan or brown. They filter almost identically. The only practical difference: a few sensitive drinkers detect a faint "papery" note from natural filters. A quick rinse with hot water before brewing washes that away and pre-heats the brewer, so most people never notice it.
Can you reuse a paper filter?
Yes — within reason. A single paper micro-filter can usually be rinsed and reused several times before it starts to tear, soften or slow the flow. Knock out the puck, rinse the filter under the tap, and set it aside. It is a small, genuinely effective way to stretch a box and cut waste. Just retire a filter the moment it looks frayed or feels mushy.
Reusable AeroPress filters: metal and the body it adds
A reusable aeropress filter made of metal is the most popular upgrade. There are two broad styles: solid stainless discs with laser-cut or punched holes, and finer etched discs with smaller, more numerous holes. Both let oils and a little fine sediment pass into the cup, which is exactly the point.
A metal aeropress filter produces a richer, fuller-bodied cup with a heavier, rounder mouthfeel — closer to a French press than a paper-filtered brew, though still cleaner because the AeroPress plunges fast. You trade a touch of clarity and a small amount of sediment at the bottom of the cup for noticeably more texture and a stronger sense of the coffee's oils.
Hole size matters. Coarser stainless discs (larger holes) pass the most oil, fines and body. Finer etched or "gold-tone" discs have smaller holes, so they give much of the body of metal while letting through fewer fines — a middle ground for people who want richness without grit. If you go metal, a coarser, more even grind helps keep sediment down; our guide to grinding coffee beans covers how to dial that in, and a decent burr grinder from our coffee grinder buying guide makes a real difference here.
Cleaning a metal filter
Metal filters need a real rinse, not just a quick swipe — oils and fines cling to the mesh. Warm soapy water and a soft brush after each brew keeps flow consistent, and an occasional soak in a baking-soda solution clears any buildup. Done properly, a metal disc lasts effectively forever, which is the whole appeal.
Cloth AeroPress filters: the quiet middle ground
Less common but worth knowing: fine-mesh cloth filters. Cloth blocks more fines than metal but lets through more oil than paper, landing between the two for a cup that is full but smooth, with very little sediment. The catch is maintenance. Cloth must be rinsed thoroughly, kept damp or frozen between uses, and replaced periodically — left to dry dirty, it can pick up off-flavours. For most people cloth is a niche choice, but fans love its texture.
Sizing: which filters fit which AeroPress
This is simpler than it looks. The standard AeroPress filter fits almost the entire line:
- Standard size — the Original, Clear, Premium and the travel-friendly AeroPress Go (and Go Plus) all share the same standard filter. One paper box or one metal disc covers all of them.
- AeroPress XL — the larger XL uses its own bigger filter. Standard discs are too small for it; buy the XL-specific paper or metal filter.
So if you own a regular AeroPress and an AeroPress Go, you do not need two kinds of filter — only the XL breaks the pattern. In a pinch you can cut a circle from a standard paper coffee filter to fit a standard AeroPress, but purpose-made micro-filters are thin, cheap and far more consistent, so cut-to-fit is best kept as an emergency trick.
Inverted method, the Prismo and Flow Control caps
How you brew interacts with your filter choice. The inverted method (assembling the AeroPress upside down to steep before flipping) works with any filter — it is about preventing drips during a long steep, not about the filter itself.
Pressure attachments change the maths. The Fellow Prismo, for example, is a filter-cap attachment with its own reusable etched-metal disc and a valve that builds pressure for a more espresso-style, concentrated shot, while also creating a no-drip seal so you can skip inverting. Some people stack a paper filter on top of the Prismo's metal disc for a little extra filtration and back-pressure. Flow Control caps similarly add a valve so you can steep without dripping. The takeaway: these accessories either replace the paper filter with metal or sit alongside it — they do not require any special "filter," just the standard one or their own built-in mesh.
Paper vs metal vs cloth: comparison table
| Filter | Taste | Body | Sediment | Cost over time | Cleanup | Eco |
|---|---|---|---|---|---|---|
| Paper | Bright, clean, clear | Light | None | Ongoing (cheap per cup) | Easiest — toss the disc | Compostable, but single-use-ish |
| Metal | Rich, fuller, more oils | Heavy | Slight | One-off, then free | Needs rinsing and scrubbing | Reusable for years |
| Cloth | Full but smooth | Medium-full | Very little | Low, replace occasionally | Most effort — rinse, store damp | Reusable, low waste |
Which AeroPress filter should you choose?
Here is the honest verdict:
- Choose paper if you want the cleanest, brightest, most flavour-forward cup, value zero sediment, and like the easiest cleanup. It is the right default for most drinkers and for showcasing good light and medium roasts.
- Choose metal if you prefer a heavier, fuller body, want to brew darker roasts with more texture, hate buying consumables, or care most about cutting long-term waste. Expect a little sediment and a bit more washing-up.
- Choose cloth if you specifically want body and a clean, sediment-free cup and do not mind fussy upkeep.
Plenty of people keep both paper and metal on the shelf and switch by mood, roast or beans. They cost little, take no space, and give you two distinct cups from the same brewer. If you are still setting up your gear, our broader how to make coffee guide puts the AeroPress in context alongside other methods — and once you have settled on a filter, the only thing left is to keep dialling in your grind and ratio until the cup is exactly yours.
