Description

Convex bottom effectively concentrates water flow towards the center of the basket. The unique shape and hole pattern enhance the extraction process, yielding notes of ripe fruit, increased acidity, and an impressive crema. Optimized for all coffee roasts.

Developed in collaboration with IMS, this product differentiates itself from the IMS Precision Competition Filter Basket (model DL2TH26E) through its distinct convex bottom design.

Help & Advice

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.
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.

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.
