An example system comprises a water-soluble unit dose article comprising a water-soluble fibrous non-woven sheet and a granular laundry detergent. The water-soluble fibrous non-woven sheet is shaped to form a partially sealed internal compartment and has an air permeability comprised between 5 m/m/min and 200 m/m/min. The granular laundry detergent is comprised within said internal compartment and comprises a plurality of particles, wherein the plurality of particles comprises zeolite particles. The system comprises sealing jaws, wherein at least one of the sealing jaws is a heated sealing jaw, wherein a bottom seal of the internal compartment is sandwiched between the jaws. The jaws comprise a non-stick coating in contact with the bottom seal and a first dust extraction conduct to direct a gas flow away from an area surrounding a top section of the sealing jaws or away from a bottom section of the internal compartment.
