(Ridged filter baskets have a groove in the side wall which a spring in the portafilter locks in to help retain the basket in the portafilter. Ridgeless, or unridged baskets, have smooth walls and as a result generally require a stronger spring to ensure they stay in place when knocking out used coffee pucks. )


  • VST's new 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)
  • All VST Filters are WARRANTED for ONE-YEAR and for ZERO DEFECTS, and 100% of VST's filters are inspected on the VST Digital Filter Imaging System
  • 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 (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 (see VST Warranty)

Customer Reviews

  • Author: Charles
    The 20g version **does not** fit the stock portafilter of the Rancilio Silva. The 18g fits perfectly!
  • Author: Grimley
    Charles is correct. 18g is the way to go for the stock Rancilio portafilter. Snug as a bug, larger, easier tamping without the ridge. Recommended.
