Official filters used during the prestigious World Barista Championship in 2012, 2013, 2014 and 2015. They allow for uniform extraction due to their precise hole arrangement keeping + /- 1 mm distance. All the holes are inspected for shape, proper distribution and errors.

Calibrated Filter Basket - the main difference between a calibrated filter basket and a standard one is the precision of hole crafting. A calibrated filter guarantees perfectly repeatable espresso extraction. Thanks to laser-cut and optically inspected holes, the water flow is uniform, allowing for fuller extraction of flavor notes and preventing channeling.
