Filter Baskets for the De'Longhi COM530M
- Size matches the 51mm De'Longhi COM530M group.
- Listing claims compatibility with DeLonghi machines.
- Portafilter ear/lug geometry for this machine is unclear (Unclear). A third-party 51mm bottomless or spouted portafilter - even at the correct diameter - may not lock into this group. Verify the exact ear/lug pattern against your specific unit before buying any replacement portafilter.
- This is a drip-plus-espresso combo, not an enthusiast machine; De'Longhi does not sell a documented aftermarket-accessory line for its group, so most 'universal 51mm' parts are a gamble.
- The included plastic tamper is 51mm-nominal and low quality; a better 51mm tamper is a safe upgrade, but confirm the diameter fits your basket lip before buying.
- Dose range 14-18g - match it to your grinder output.
- What size to buy
- Buy 51mm for the De'Longhi COM530M.
- What to avoid
- Avoid 54mm and 58mm filter baskets - they will not fit the 51mm group.
- If you own another machine
- Own a Breville Bambino? Use the 54mm page instead - these 51mm parts will not fit it.

Before buying filter baskets
Does any 51mm filter basket fit the De'Longhi COM530M?
No. The nominal size is only the first check. Model-specific locking geometry, basket depth, mounting pattern, or clearance may also matter. Portafilter ear/lug geometry for this machine is unclear (Unclear). A third-party 51mm bottomless or spouted portafilter - even at the correct diameter - may not lock into this group. Verify the exact ear/lug pattern against your specific unit before buying any replacement portafilter.
Is a filter basket the first upgrade to buy?
Not automatically. The De'Longhi COM530M's stored upgrade order starts with tamper; fix grinder, basket, dose, or maintenance issues before adding optional tools.
