IMS Filter Basket for 51mm Portafilters, Convex

Q: Why doesn’t the IMS basket fit into my original Dedica portafilter?

The original Dedica portafilter includes a plastic internal insert designed for pressurized baskets. This insert prevents precision baskets from seating correctly and must be removed before installing certain IMS baskets. How to remove the plastic insert from the Dedica portafilter: Remove the basket (use a small spoon handle or flat tool to lift it out). Look inside the portafilter: you will usually see a black plastic insert and/or a plastic ring beneath where the basket sits. Pry out the insert carefully: Use a small flat screwdriver or pick . Start at the edge of the plastic part and lift it up gradually. Work around the circle rather than forcing one spot. Remove any separate plastic ring if present (some versions have more than one plastic piece). Clean the portafilter and ensure only the metal body remains where the basket seats. Install the IMS basket directly into the portafilter until it snaps in and sits flush. If you cannot see a removable plastic piece: Some Dedica portafilters differ by version/market. If the plastic part appears fixed or you’re unsure, stop and contact us with a photo of the inside of your portafilter - we’ll confirm what needs to be removed before you force anything. Important: Remove plastic parts only. Do not bend or remove any metal lip or retaining spring that holds the basket in place.

Q: How to recognize an IMS basket?

Every genuine IMS basket has two engravings: Lot number – identifies the production batch and ensures full traceability for quality control and distribution. IMS code – indicates the exact model and dimensions of the basket. This system guarantees authenticity and helps you confirm you’ve received the correct product.

Is this IMS basket compatible with 51 mm tampers?

IMS baskets are compatible with DeLonghi original and most custom tampers. Some tamper manufacturers make “precision” tampers with a very tight fit. Unfortunately, they do not leave any space for air and even small particles of coffee can make tamper to get stuck in the basket.

Every genuine IMS basket has two engravings:

Lot number – identifies the production batch and ensures full traceability for quality control and distribution.

Why was my IMS basket packaging open?

IMS packs baskets in a small cardboard sleeves that may sometimes shift or loosen in transit. This does not mean the product is used or fake. Every basket we sell is new, unused, and shipped exactly as we receive it from IMS.

Could I have received a “fake” IMS basket?

No. All our IMS baskets come directly from IMS in Italy, in their official packaging.
