Description
The Finum tea filters in size XL are the perfect replacement for the now discontinued T-sac tea filters No. 4. These tea filters are the ideal solution for anyone who enjoys the convenience of tea bags but prefers loose leaf tea or herbs. They make it quick and easy to brew a delicious pot of tea – wherever you are.
Why are these filters so convenient?
- Handy filling flap: The smart flap prevents spills when filling and makes it easy to remove the filter afterward, even without a holder.
- Close like a tea bag: You can fold the flap and secure it using a filter holder or the Finum® Filter Stick. The stick rests across your cup or stands upright in a teapot, allowing easy removal of the filter afterward.
- Expandable bottom for better infusion: The bottom of the filter offers enough space for the tea leaves to fully release their aroma.
