Made from microfine stainless steel, Finum permanent tea filters provide superior brewing for all sorts of tea, large and small leaf alike. The stainless steel affects neither taste nor aroma, so every pot is guaranteed to contain nothing but pure, fresh-brewed goodness. Our large filter is particularly good for larger teapots of 4 cups or more. Measures 2 5/8 in. diameter, 3 7/8 in. high.
