Hario Filter-in Bottle

While the bottle is constructed from heatproof glass, it is specifically engineered for cold brewing. We recommend sticking to cold or room-temperature water to ensure the silicone and plastic components maintain their integrity over time.

The integrated filter is designed to handle standard loose-leaf teas quite well. However, if you are using very fine, powdery teas like certain Japanese green teas, you may notice some sediment in the final pour.

Yes, the entire assembly is dishwasher safe. We recommend placing the glass bottle in the bottom rack and the smaller plastic and silicone components in the top rack to prevent any potential warping.

With a diameter of 3.54 inches, it is designed to fit most standard refrigerator door pockets. It is always a good idea to measure your specific fridge shelf depth before purchasing to be certain.

The filter is fully removable, which makes cleaning straightforward. Simply pull it out from the spout and rinse it under warm running water; for a deeper clean, a soft bottle brush works perfectly to dislodge any stubborn leaves.

The lid is designed to stay secure while pouring, but it is not a leak-proof, airtight seal. We strongly recommend storing the bottle in an upright position to prevent any accidental spills.
