Step 2 – Add Coffee Grounds Add your favorite ground coffee directly into the filter.
Step 3 – Pour Hot Water Slowly pour hot water over the grounds for a smooth pour-over extraction.
Step 4 – Ready to Drink Remove the filter and enjoy freshly brewed coffee straight from the insulated mug.

Recommended Grind Size: Our filter works best with medium grind (similar to sea salt). Very fine grounds can clog the mesh, causing extremely slow flow. Extra coarse grounds may lead to under-extraction and weak flavor.
Solution for Fine Grounds: If you prefer a finer grind (e.g., for a stronger brew), you can place a paper filter on top of our metal mesh. This will prevent clogging while allowing proper flow.
Dosage & Technique Tips: Fill the filter no more than 2/3 full to avoid compaction. Use 195–205°F (90–96°C) water and pour in slow, steady circles. Avoid stirring aggressively.
