## Fits these machines

- Gaggia Classic GT (58mm portafilter) — https://espressofit.com/machines/gaggia-classic-gt/
- Gaggia Classic Pro (E24) (58mm portafilter) — https://espressofit.com/machines/gaggia-classic-pro/

## Notes

Gaggia's own-branded bottomless (naked) portafilter for the Gaggia Classic,
with an ashwood handle. Gaggia states a 59 mm holder-body diameter; it seats
Gaggia's 58 mm-standard baskets (and, per Gaggia, the wider IMS B70 20g filter
it ships with — see the Gaggia Barista Pro IMS 20g basket entry). Bottomless
portafilters remove the spout so you can watch the extraction and diagnose
channeling. Verified against Gaggia's official accessory page on 2026-07-07.

## Sources

  - Official Gaggia accessory page, read firsthand 2026-07-07. States verbatim: 'Bottomless Filter-holder: professional bottomless filter holder with ash wood handle, for Gaggia Classic. Gaggia logo on the handle, stainless steel filter housing and spouts. Filter holder diameter: 59 mm. Total length: 220 mm.' The 59 mm is the holder body; the machine uses the 58 mm portafilter/basket standard, which is why it is listed under 58mm. Sold with the Barista Pro IMS 20g filter (a separate basket entry).
