MHW-3BOMBER 58mm Espresso Filter Basket, 18g

The MHW-3BOMBER 58mm espresso filter basket is an 18g stainless steel basket for home espresso drinkers who want to get more deliberate about their shots. If you're working on your grind, dose, and puck prep, this is the kind of detail I'd look at next: a straight-sided, flat-bottom basket with dual-layer filtration and 745 laser-drilled holes.

This is the portafilter basket I have been using for almost a year and I have to say that I have enjoyed the espresso that it makes. I especially enjoy that it has a coating that helps pop out the puck without leaving an residual grinds in the basket. 

What makes this basket different?

The inner filter helps keep ultra-fine coffee particles from passing into your cup, while the outer layer supports the inner mesh. The straight sides, flat bottom, and precision perforations are designed to encourage even extraction. That gives you a basket built around consistent water flow, rather than a promise that a new part will fix every shot.

I would still pay attention to the basics. Fresh coffee, an appropriate grind, and even puck preparation matter. Think of this basket as one part of dialing in your espresso, not a shortcut around it.

The details that matter

• Size and dose: 58mm-class basket with a nominal 18g capacity and a recommended coffee dose of 17–19g.
• Filtration: Dual-layer construction with 745 laser-drilled perforations.
• Shape: Ridged basket with straight sides and a flat bottom.
• Material: Food-grade SUS304 stainless steel for corrosion and oxidation resistance.
• Reinforced base: A 0.8mm-thick bottom designed to resist deformation under brewing pressure.
• Model: FB5628.

Will it fit your portafilter?

This basket is intended for most 58mm portafilters; the basket specification also lists a 58.5mm measurement. Compatibility examples include Breville BES980XL, BES920XL, and BES900XL; Gaggia Classic, Pro, and Evo; and compatible Bezzera and E61-style setups. Check your exact portafilter's basket diameter and depth before ordering rather than relying on the machine brand alone.

Some tight or shallow 58mm setups will not accommodate it, including Casabrews 58mm models. A 58mm label by itself does not guarantee a fit.

Where I'd start

Start with an 18g dose, distribute the grounds evenly, and tamp level. Dial in your grind for your coffee and recipe, then make one adjustment at a time. The recommended 17–19g range gives you room to adjust the dose while checking that the coffee puck has enough clearance in your setup.

If you already have a compatible 58mm portafilter and enjoy fine-tuning your espresso, this is a practical basket to consider for your next round of dialing in.
