Why IMS Competition precision sieves?

The 715 round holes with a conical cross-section are a patented IMS innovation. They ensure significantly better crema formation and a more even flow through the entire coffee puck – right to the edge. The cylindrical shape with a flat bottom was developed by IMS to achieve the optimal ratio between the base and height of the coffee puck.

Your benefits at a glance

• Improved extraction : Consistent water flow through precisely machined holes
• Better crema : Patented cone-shaped hole structure for optimal crema formation
• Clean handling : Drier coffee puck, easier knocking out.
• Durability : High-gloss polished stainless steel AISI 304 – less coffee residue, longer lifespan
• With clamping ring : Minimal rim (ridge) for a secure hold in the portafilter

From the community: What you should know

In espresso forums, users report that the recommended doses can vary between different shops. The portafilter basket height is the most reliable indicator . Some baristas successfully use 18g in a 24.5mm basket, while others find that too much – experiment to see what works best for your roast and machine.

Important : If you switch from standard filter baskets to IMS precision filter baskets, you will need to readjust your grind setting . The more precise perforation often allows for slightly finer grind settings.
