IMS Precision Series Filter Basket

The B652TH27.5M is specifically designed for 65mm portafilters and is a perfect fit for the 9Barista espresso machine. Please verify your machine's portafilter size before purchasing to ensure a proper seal.

This basket is designed for use with a 53mm tamper. Using the correct size ensures an even puck density, which is essential for consistent extraction.

The average capacity for this model is 15 to 17 grams of coffee. You may need to adjust your dose slightly based on the roast level and grind size of your beans.

The patented 641-hole micro-perforation pattern is engineered to improve water flow and distribution. This results in a more balanced extraction that highlights the sweetness and fruit notes of your coffee while producing a rich crema.

Not at all. The basket is made from electropolished AISI304 stainless steel, which is food-safe and resistant to corrosion. Simply rinse it with hot water after use and ensure it is completely dry before your next brew.

The cylindrical shape with a narrowing base helps create a more compact coffee puck. This design promotes uniform water resistance throughout the bed, leading to a more precise and consistent extraction.
