The Teeli filter is what we believe to be the best tea strainer for loose leaf teas to date. The micro-mesh doesn't let tiny particles through, which makes it so popular with our customers.

This filter is available in two sizes:

Medium - good for mugs and small teapots (up to 3 cups; teapot width 2.5" / 6.5 cm)
Large - good for larger teapots (3+; teapot width 2 3/7" / 7cm)
