IMS Competition Filter Basket

The convex shape directs water flow toward the center of the puck rather than allowing it to channel along the edges. This promotes a more uniform and concentrated extraction, which can lead to a cleaner, more balanced espresso shot.

Yes, this basket is designed for standard 58mm portafilters, specifically those found on E61 group head machines. However, because it is a precision basket, we recommend using a 58.5mm tamper to ensure a snug fit and even compression across the entire coffee bed.

The ridgeless design provides a smooth, straight wall from top to bottom. This makes it significantly easier to knock out your spent coffee puck cleanly after brewing, and it also prevents coffee grounds from getting trapped in a ridge during the tamping process.

This basket is designed for a 20g dose. While you can experiment slightly based on your roast and grind size, 20g is the optimal capacity to ensure proper headspace between the coffee puck and the shower screen for consistent extraction.

Electropolishing removes microscopic imperfections from the stainless steel surface. This creates a smoother finish that resists coffee oil buildup and makes the basket much easier to clean, ensuring your equipment stays hygienic and performs consistently over time.
