Technical information

Directions for use

Ecozen® plastic, like aluminium, is not an isothermal material. Use a specially designed, insulating bag if you want to keep liquids cool in your water bottle. This water bottle can be used for hot drinks but they will cool quickly.
The product can be used with fizzy drinks. Do not put in the microwave or freezer.


The top is easy to open with one hand by pressing on the white button marked "PRESS". When carrying the flask, you can lock this button by sliding the white button down. A red area appears, indicating that the top is locked and it can no longer be pressed. It also has a filter so you can infuse fruits for example.
The water bottle is transparent and graduated 300 ml by 300 ml to be able to see the remaining liquid.

Care tips

Clean your water bottle after every use with conventional washing-up liquid and water. The product can also be put in the dishwasher if necessary. Please note that when in the dishwasher the seal of the cap might come off. If this happens, remember to replace it as it helps keep your water bottle watertight. Allow the cap and bottle to dry separately.
Soak overnight in a mix of bicarbonate of soda and water for deep cleaning.

First use

Rinse the entire product 3 times with clear water before using for the first time.
