The Breville Barista Express comes with two types of filter baskets: Dual Wall and Single Wall. The key difference is pressure control - Dual Wall filters are pressurized, creating artificial pressure to help beginners pull a consistent shot, while Single Wall filters are non-pressurized and require precise user skill for a true, cafe-quality extraction.
Here's everything you need to know to pick the right filter basket from Breville for your skill level and coffee goals.
Breville Barista Express Dual Wall Filters
Dual Wall filters, also known as pressurized baskets, are designed specifically for aspiring home baristas. They feature a double-layered base with one small exit hole, which creates back-pressure during the extraction process. This technology ensures a decent shot of espresso even if your coffee grind size or tamping pressure isn't perfect, making it a forgiving tool for learning.
- What it is: A set of semi-pressurized filter baskets that standardize espresso extraction, making them easy to use for beginners.
- Key features: Double-layered wall design that artificially creates resistance, forgiving of inconsistent grind sizes, produces a thick layer of crema with minimal effort. Typically includes a single shot and a double shot basket.
- Price: Included with the machine, replacement sets cost around $15–$25.
- Materials/Construction: Durable stainless steel built for longevity and consistent heat retention. The bottom of the basket has a second layer with only a single pinhole for coffee to exit.
- Pros: Extremely beginner-friendly and forgiving. Great for use with pre-ground coffee. Consistently produces decent shots and a visually appealing crema. Reduces channeling issues for novices.
- Cons: Lacks fine-tuned control over the extraction. The crema produced is more like a foam and can hide the true flavor complexities. Can give a false sense of a perfect shot, hindering skill development.
The Dual Wall basket is for anyone who wants a straightforward, reliable cup of espresso without worrying about the precise variables of coffee making.

Breville Barista Express Single Wall Filters
Single Wall filters are the traditional, non-pressurized style baskets used by professional baristas. These filters feature a simple, single layer of metal full of tiny, uniform holes. For a successful extraction, every variable - grind size, dose weight, distribution, and tamp pressure - must be just right. This gives you complete control over the final shot, allowing for true flavor expression from your beans.
- What it is: A set of non-pressurized, traditional filter baskets that offer full control and feedback over the brewing process, intended for skilled users.
- Key features: A single layer of stainless steel with hundreds of precisely drilled holes. Directly responds to grind size and tamping pressure. Unlocks the full flavor potential of fresh coffee beans.
- Price: Included with the machine, replacement sets cost around $15–$25.
- Materials/Construction: High-quality stainless steel with a perforated bottom, designed for even water flow through the entire coffee puck.
- Pros: Offers complete command over every brewing variable. Capable of producing truly exceptional espresso with nuanced flavors. Provides clear visual feedback on your technique, helping you improve. Allows for the extraction of authentic crema based on bean freshness.
- Cons: Has a steep learning curve and is completely unforgiving of mistakes. Requires a high-quality, consistent burr grinder. Can be frustrating for beginners as it may produce watery, sour, or bitter shots initially.
This is the filter of choice for coffee hobbyists and anyone serious about mastering the craft of manual espresso extraction for the Barista Express.

Dual Wall vs. Single Wall Filters Comparison
Ease of Use & Learning Curve
There's a massive difference here. The Dual Wall filters are the "training wheels" of espresso. Their pressurized design compensates for common beginner mistakes like an uneven tamp or a slightly off grind size, making it much easier to achieve a drinkable shot right away. You get consistent results without a lot of frustrating trial and error.
The Single Wall filters have a steep learning curve. They give you all the control, which also means they expose every flaw in your process. Your grinder must produce a uniform grind, and your tamping needs to be level and consistent. The feedback is raw and immediate - perfect shots are incredibly rewarding, but bad ones are nearly undrinkable. This basket demands practice and precision.
Extraction & Flavor Control
This is where Single Wall baskets truly shine. Because you control all the variables, you can "dial in" a shot to perfectly extract the complex flavors of your specific coffee beans, whether they are fruity, chocolaty, or nutty. The quality of your espresso is a direct reflection of your skill.
The Dual Wall basket, by creating artificial pressure, tends to standardize the flavor. It smooths over imperfections but also mutes the subtle, nuanced notes that make a specific coffee bean unique. While it produces a thick and stable crema, this crema is largely a product of pressurization, not a true indicator of fresh coffee extracted perfectly.
Materials & Durability
Both filter basket types are made from high-quality stainless steel and are built to last. For a standard home user, both will hold up for years with proper cleaning. You do not need to worry about one being more durable than the other, the difference is purely functional.
Price & Value
As both Dual Wall and Single Wall baskets are typically included with the Breville Barista Express, there is no initial cost difference. Replacement sets are also very affordable at around $15–$25. The "value" lies in the experience. The Dual Wall basket's value is in its consistency and simplicity that allows you to make a decent espresso without much effort. The Single Wall basket is valuable for unlocking the full potential of your machine and beans, offering long-term improvement for anyone who wants to grow their barista skills.
Which One Works Best For You?
The Dual Wall filter is ideal for anyone new to espresso. It's perfect if you're a beginner or someone who just wants a decent espresso with minimal fuss. On the other hand, the Single Wall filter is made for enthusiasts and those serious about perfecting the art of espresso. If you have a quality burr grinder, fresh beans, and enjoy the process of perfecting shots, this is the basket to provide the most rewarding experience.
Both baskets serve excellent purposes within the Breville Barista Express system, but ultimately cater to very different skill levels. Choose the Dual Wall filter if you prioritize consistency over customization. You can still enjoy a reliable cup of coffee without stressing over the finer details. Choose the Single Wall filter if you're adventurous and seek to explore the depths of espresso flavors at home. This basket provides a platform to hone your skills and experiment with every aspect of your espresso.
