breville filter

Available sizes are 58mm portafilters and 54mm filter baskets. The 54mm baskets are offered in three shot sizes (single, double, triple) with gram ranges noted in the product details.

It’s a bottomless (naked) 58mm portafilter that lets you visually monitor extraction. It includes a double-shot, single-wall filter basket and a 15° tilted handle for ergonomic use.

Single shot: 8–11 g Double shot: 16–18 g Triple shot: 18–22 g

Because they expose the basket’s outlet, bottomless portafilters let you see the entire extraction flow. That visibility makes it easy to spot problems like channeling, spurting, or uneven flow so you can identify and correct extraction issues that a spouted portafilter would hide.

Dimensions: 2.25 in (H) × 4.25 in (W) × 10.25 in (D). Weight: 1.2 lb.

Yes. The 54mm baskets use the same tapered profile as original Breville 54mm baskets, so a 53.3mm tamper remains a proper fit.
