VST Precision Filter Basket 22gr Ridgeless ,

Experience uniform extractions across all groups for the first time – permanently. The essential espresso filter for those in search of the ultimate cup.
VST precision baskets suit any E-61 group heads or that measures 60mm in diameter. VST basket is recommended for use with the following machines: La Marzocco, Kees Van Der Westen, Synesso, Slayer, Nuova Simonelli, Faema, La Cimbali, VBM and Rancilio with standard portafilters.
The Ridged or standard basket has an indented ring near the top. This ring is called the ridge, which presses against the spring to hold the basket in the portafilter. The Ridgeless basket on the other hand is held in by tension.


Every hole in VST Precision basket is measured on every filter for minimum and maximum range limits on area and diameter, giving them the ultimate precision.

Each VST filter is serialized with a unique 2-D code to ensure authenticity and performance. Each unique 2-D code references stored factory measurement, quality reports and image data.

Measurements stored in VST database for all filters, summary quality report included with each filter.

Each filter is graded and warranted to perform identically to similar grades.


  • VST's precision filters deliver consistent extraction performance over a wide range of concentration with reduced sediment
  • Designed to extract properly as a ristretto, normale or lungo with minimal or no change in grind setting at a fixed dose
  • Filters are matched for total square area to +/- 5% to ensure identical performance (typical variances of standard filters range from 50-200% of nominal open square area)
  • Holes are fabricated using a new micro-machine and finishing process
    100% of holes are measured on every filter for min/max range limits on area and diameter to a precision of +/- 20 µm (individual QC report provided with every filter). All holes are measured for circularity, placement, square area and blocked holes
  • Hole pattern is centered to +/- 1.0 mm and placement is oriented for uniform extraction throughout the entire puck
  • Wide outlet angle to prevent filters from clogging, anti-wear design ensures uniform performance for life of product
  • Improved structural integrity, will withstand deflection from pump cycling without premature fatigue failures
