Whats Unik about Espro is their patented and unique double filter, which sits inside the piston jug.
- It is about 3-5 times finer in the netmask (hole size in the filter called 'mesh size') than other stamp jugs. You get a perfectly clean cup of Tea, without bitterness.
- When the filter is pressed down after the end of the brewing time, the finished tea leafs is isolated from the your beverage, which means that your tea does not continuing brewing.
The Espro can also be used as a thermo jug, as it has double-walled outer walls, which keeps your tea warm for a very long time after brewing, especially because the walls are vacuum insulated.
