MHW-3Bomber DH Filter Basket
MHW-3Bomber DH Filter Basket: 58mm
The MHW DH Filter Basket is engineered for medium-dark and dark-roasted beans. Its multi-aperture design ensures smoother extractions and richer flavours, enhancing every shot with greater clarity and balance.
How the MHW DH 18g Filter Basket Works
This filter basket features a three-tier aperture pattern (0.2mm, 0.25mm, 0.3mm) arranged in equidistant concentric circles. The smaller outer holes increase puck resistance to slow flow, while the larger inner apertures improve centre flow. This pressure balance reduces channeling and improves flavour consistency in darker roast extractions.

Comparison & Performance Insights
When tested against a standard basket using the same dark roast coffee, the DH Filter Basket produced:
- Higher sweetness with reduced bitterness.
- More balanced mouthfeel with improved textural clarity.
- Lower extraction rate (19.02% vs 19.64%) but better flavour yield.
- Lower TDS (9.78% vs 10.1%), reflecting a cleaner cup.
The result? A more nuanced and syrupy espresso—especially when dealing with darker roast profiles.
Maintenance & Cleaning
- Rinse after each use and backflush weekly to maintain optimal performance.
- Slight polish marks from production are normal and do not impact function.
- Safe for both café and home environments.
Best Practices for Brewing
- Pair with medium-dark to dark roasts for best results.
- Use even distribution tools for maximum extraction efficiency.
- Ideal for baristas using 58mm commercial machines.
Questions & Answers
-
Is the MHW DH Filter Basket compatible with all 58mm portafilters?Yes, it fits most standard 58mm espresso machines and portafilter handles. Always check basket depth clearance for precision fit.
-
Does the 18g marking refer to exact capacity?No. The 18g refers to a specification standard. The actual dose may vary slightly depending on grind size and bean density.
-
What makes it ideal for dark roasts?The multi-aperture design moderates flow and reduces pressure inconsistencies, helping bring out more sweetness and less bitterness from darker beans.
-
Is it suitable for light roast extractions?While it can be used for lighter roasts, it's optimised for medium-dark and dark roast profiles due to its flow control dynamics.
-
Can it improve flavour and texture?Yes. Tests show increased sweetness, reduced bitterness, and a smoother mouthfeel versus standard filter baskets.
