Cona Precision Weave 30 Micron Filter
Cona stainless steel precision weave 30 micron filter for use in your Cona coffeemaker.
The filter is firmly held in place by a spring and so enables agitation during brewing, you can't do that with the glass rod.
It is recommended to put the 'Precision Metal Weave filter' in a dishwasher at least once every 30 working cycles to remove fatty residue. Or run a cleaning cycle with nothing but hot water and an espresso-machine-tablet or 1/4 of a dishwasher-detergent-tablet placed in the funnel.
