Simply spoon in your loose leaf tea, add water, replace the stainless steel filter and you’re ready to go! This filter allows you to infuse tea or fruit and stays in place so only your tea or detox water is filtered out, while the double-walled design keeps its contents at your desired temperature. It’s made entirely of borosilicate glass, making it suitable for either hot or cold liquids, and the sturdy soft-touch lid is easy to open and close.
