## Notes

Breville's OEM dual-wall (pressurized) two-cup basket for its 54mm portafilter
machines, sold as replacement part SP0001521. The part page itself only says
"for multiple Breville Espresso Machines"; the cross-references here are to
machines whose own official pages state they use a 54mm portafilter and ship
with dual-wall baskets (Barista Express BES870, Bambino BES450, Barista Pro
BES878, Barista Touch BES880, Duo Temp Pro BES810, Infuser BES840). Verified
against Breville's official pages on 2026-07-04.
Dual-wall baskets are pressurized — Breville's design for pre-ground or
inconsistent grinds. Does not fit 58mm machines.

  - Official Breville (US) replacement-part page, read firsthand 2026-07-04. Product name verbatim: '54 mm Filter 2 Cup Dual Wall', described as being 'for multiple Breville Espresso Machines'. Breville does not list the specific models on this page — the machine cross-references below come from each machine's own official product page. Amazon listing verified firsthand 2026-08-03: 'Breville .BES860XL/11.41 Two Cup Dual Wall Filter, 54mm' — Breville-branded, and the listing states two-cup, dual-wall and 54mm, matching this entry's brand, size and variant. Add-to-cart present, i.e. actually buyable, at the time of checking.
- https://www.breville.com/en-us/product/bes870
  - Official Barista Express BES870 page, read firsthand 2026-07-04: the machine has a '54 mm stainless steel portafilter' and ships with '1 cup & 2 cup Single & Dual Wall Filter Baskets' — i.e. this basket type is the machine's own OEM configuration.
- https://www.breville.com/en-us/product/bes450
  - Official Bambino BES450 page, read firsthand 2026-07-04: '54 mm portafilter delivers full flavor with dual and single wall filters', with '1 cup & 2 cup Single Wall & Dual Wall Filter Baskets' included.
- https://www.breville.com/us/en/parts-accessories/parts/sp0024833.html
  - Official Breville (US) replacement-part page for SP0024833, read firsthand 2026-08-26. Breville lists this SECOND code with a description identical to SP0001521 — product name verbatim '54 mm Filter 2 Cup Dual Wall' — at the same price, differing only in the model featured in its 'Works With' block ('the Bambino® - BES450'). Breville publishes no dimensional difference between the two codes and does not say whether one supersedes the other, so both are recorded here and neither is presented as the correct one to order.
