With the Bottle with Filter, making a good iced tea is very easy: unleash your imagination and add fruit, herbs, and much more to your infusions. Place the bottle in the refrigerator and let it infuse for at least 30 minutes. The filter is applied to the silicone cap, allowing you to pour and filter simultaneously. All parts are removable, so it is easily washable, even in the dishwasher. Material Thanks to borosilicate glass, no odor will remain inside the bottle. In fact, this type of glass is non-porous, so after a thorough wash, any residue will be cleaned, and the bottle will be like new. Borosilicate glass is known for its low thermal expansion coefficients and is less prone to thermal stress.
