About This Product

The Filter Funnel can be supplied on export terms to Italy, Sri Lanka, Ecuador, Rwanda and Bahamas.
Frequently Asked Questions
Why does the Filter Funnel have a 60° cone?
A filter paper folded into quarters opens to a 60° cone, so it sits snugly against the glass and filters evenly.
