MHW-3BOMBER DH Filter Basket

This basket is designed with a standard 58mm diameter, which is compatible with most commercial-style portafilters. However, you should verify that your machine specifically uses a 58mm group head, as some home machines utilize smaller sizes like 54mm or 51mm.

The MHW-3BOMBER DH basket is engineered for precision, often featuring more consistent hole patterns and better structural integrity than standard baskets included with entry-level machines. This can lead to more even water distribution and, ultimately, a more balanced espresso extraction.

No special tools are required. Most baskets are held in place by a spring clip inside the portafilter head; you can typically pop the old basket out by prying it gently with a spoon or a dedicated basket removal tool, then simply press the new one into place.

Yes, this basket is fully compatible with most standard 58mm bottomless portafilters. Its precision design is actually well-suited for bottomless setups, as it allows you to clearly observe the extraction quality and identify any channeling issues.

To maintain optimal performance, rinse the basket with hot water after every shot to remove coffee oils. Periodically, you should soak it in an espresso machine cleaning powder solution to dissolve any stubborn residue that can clog the precision holes.
