Description
The Finum tea filters in size XS are the ideal replacement for the now discontinued T-sac No. 1 tea filters. They’re perfect for use in tea glasses, mugs, or small cups.
Why are these filters so convenient?
- Convenient filling flap: The smart flap helps prevent spills while filling and makes it easy to remove the filter afterward – even without a holder.
- Closeable like a tea bag: Fold the flap and secure it with a filter holder or a Finum® Filter Stick. The stick rests across your glass or stands upright in a teapot, making it easy to remove the filter after use.
- Pleated bottom for optimal infusion: The bottom of the filter provides enough space for tea leaves to fully release their aroma.
