Medium vessel filter was designed as part of the "Still" series by Formafantasma. "Still" is a collection of aesthetic, contemporary, and carefully engraved crystals. These pieces are the investigation into water-purification started by the designers in 2012. The crystals engraved with two different patterns: one is a new microscopic view of bacteria found in rivers. The other is a 19th-century representation of an organism that lives in the oceans and is characterized by having a skeleton made of silica.
Formafantasma also designed a copper spoon inspired by the iconic piece and a series of copper cups to reference the Drinking service no.267 'Alpha' designed by Hans Harald Rath.
The collection includes a large vessel, medium vessel, tumbler, charcoal dish, vessel filter, cup filter, copper ladle, copper spoon, and copper cup.
