How can we help?

Your starter kit includes one Duryn One pitcher and one cartridge. Follow the setup guide supplied with the kit.

Follow the quick-start card supplied with your pitcher. Setup and cartridge-priming instructions can vary by cartridge version, so use the guide in your box or ask support for the current steps.

Fill time varies with tap-water quality and cartridge age. The current expected flow range is published with the product specifications.

Yes. Loose carbon dust from a new block comes out in the first fill, which is why we ask you to pour the first pitcher away. If it continues past the second fill, rinse the cartridge again under the tap and write to us.

Check the current product dimensions against your refrigerator shelf before purchase. Filtered water should be stored covered and refreshed regularly.

Use cold or room-temperature tap water only. Check the current care guide for the permitted temperature range.

Record your first-use date and set a reminder for 90 days. Track usage too: replace sooner if you reach 100 US gallons (approximately 379 litres). Your refill schedule can be managed using the link in your subscription email.

The current material specification is listed on the product page and packaging for your production batch.

See the current product and cartridge material specification for the exact composition of every component that comes into contact with water.

Follow the care guide supplied with the pitcher. Remove the cartridge before cleaning, keep the walnut lid out of the dishwasher, and check the guide for the current dishwasher instructions for the remaining parts.

Rinse the glass and funnel weekly. Once a month, wash with warm water and a little unscented soap, then rinse well. Limescale on the glass comes off with diluted white vinegar. Take the cartridge out before you wash anything.

Keep it dry and out of the dishwasher. Wipe spills, let it air dry, and every few months rub in a drop of food-safe mineral or walnut oil to keep the grain nourished. Wood changes colour slightly with time; that is the point of it.

The current total and funnel capacities are listed in the product specifications.

If the pitcher arrives damaged, photograph the product and packaging and contact support. Current replacement-part availability and pricing are shown in the store or provided by support.

Replacement-part availability changes over time. Check the store or contact support for the current list.

Condensation. Cold water in a room-temperature glass will sweat, especially in summer. Set it on the linen coaster or a cloth if it bothers you; it is not a leak.

There is one current option: the Duryn One Replacement Cartridge, with three filtration layers inside a single cartridge. It is designed for the Duryn One pitcher. Separate Alkaline and Softener options are not part of the current range.

Replace after 100 US gallons (approximately 379 litres) or 90 days of use, whichever comes first. Higher usage may require an earlier replacement.

Record the date you first use the cartridge and keep track of the amount of water filtered. Replace after 100 US gallons (approximately 379 litres) or 90 days of use, whichever comes first. Higher usage may require an earlier replacement. Do not wait for a change in taste or flow before following the replacement limit.

Use the replacement and priming steps printed on the new cartridge packaging. If the cartridge does not seat correctly, contact support.

The current range has one Duryn One Replacement Cartridge. Cartridge-type switching is not available.

Follow the priming instructions printed on the cartridge packaging before the first use.

Disposal options depend on your local waste rules and the cartridge version. Check the packaging or contact support for the current route.

No, in both directions. The click mount is Duryn's own, patented design, and it only works with Duryn cartridges.

Do not continue using a cartridge beyond its replacement limit. Replace after 100 US gallons (approximately 379 litres) or 90 days of use, whichever comes first. Higher usage may require an earlier replacement. Follow the supplied care guide after periods without use.

Flow can change with water quality and cartridge use. Follow the troubleshooting steps in the supplied guide and replace a cartridge that has reached its service limit. Contact support if a new cartridge does not flow correctly.

Keep spare cartridges sealed in their original packaging, in a cool and dry place away from strong smells, and use them before the date printed on the package.
