Filtration Quality (No Leaf Left Behind)
The goal is simple: water goes in, tea flavor comes out, and the leaves stay put. High-quality filtration is the holy grail of tea makers. You want a mesh that is fine enough to catch even the smallest Rooibos needles but breathable enough to let the water circulate. If your infuser leaves your cup looking like a swamp, it's time for an upgrade. We're aiming for crystal-clear infusions, not a botanical garden at the bottom of your mug.
