  • My Welly Bottle
    • What can I use my Welly Bottle for?

       You can use your Welly for anything kind of drink! Welly Bottles keep any beverage cold for 12 hours or hot for 8 hours. Whether you want your coffee or tea to stay hot long into the day or your ice water to stay cold through a long hike, we’ve got you covered!

      Carbonated beverages can be used, but be careful not to shake your bottle as it will cause a build up of pressure, which can alter the double-walled vacuumed insulation. In other words, don’t shake your carbonated beverages if you want your Welly Bottle to stay in good shape and you want to stay dry.

    • Will my Welly Bottle sweat?

      Welly's double-walled vacuum insulation keeps the outside of the bottle condensation free. Don’t sweat it!

    •  Can I put my Welly Bottle in the refrigerator, freezer, or microwave?

      No. This can damage the pressure in the double-walled vacuum insulation.

    •  What is the Welly Bottle made of?

      Welly bottles are made of premium 18/8 food-grade stainless steel, sustainably harvested bamboo, BPA-free plastic (under cap) and silicone.

    • Can the bamboo get wet?

      Our bamboo is 100% natural. We therefore ask that you take care of your Welly bottle. The bamboo can get wet but we ask that you try to minimize contact with water. Do not submerge your bottle underwater as this can affect the vacuum insulation.

    •  Where is the Welly Bottle made?

      Our bottles are responsibly made in China. We have visited our bottle and filter suppliers and their manufacturing facilities to be sure they are up to our quality assurance standards.

    • What is the size and weight of a Welly Bottle?

      9.29"H x 2.83"W, 1 lb.      

    • What is my donation to charity: water used for?

      Your donation goes DIRECTLY to building wells of clean water in undeveloped countries through charity: water. Welly has already donated thousands of dollars to charity: water thanks to you!

  • Caring for my Welly Bottle
    • How do I clean my Welly Bottle?

      As with all bottles, we recommend cleaning your Welly bottle often to prevent bacteria build up. Handwash only with hot, soapy water. Use a brush to scrub it thoroughly. To get a deeper clean we recommend Bottle Bright Cleaning Tablets or a mixture of hot water, soap and vinegar.

    • Can I put it in the dishwasher?

      Sorry, looks like you’re going to have to get your hands dirty. You cannot put your Welly in the dishwasher. It can only be handwashed.

  • Filter
    • What is my filter made of?

      Our filters are made of bamboo through a Japanese process that is equal parts high-science and storied tradition. The sustainably harvested bamboo is grown in the Fujian Forest, in southeastern China. After a minimum of five years of growth, the bamboo stalk is harvested and baked in a specialized kiln for 25 days. The filter naturally absorbs chlorine, taste, odor and heavy metals like lead out of your tap water.

    • How do I use my filter?

      Once you clean it, just drop it in your Welly Bottle and fill your bottle with water! Then, let the filter work its magic!

    • Do I need to clean my filter before using it?

      Yes! If you do not clean the filter it may not work to the best of its abilities.

    • How do I clean my filter?

      Rinse the filter under running water to remove its protective ash (you may notice the ash rub off on your hands- this is completely normal). Once you wash it thoroughly, you’re good to go!

    • How long does the filter last?

      The filter will last for 4 weeks of use before you should clean it again. To do this, boil the filter in water for 10 minutes and let it dry (preferably in sunlight) for another 10-15 minutes. This will remove any contaminants stuck in the filter, re-open the pores of the bamboo, and expand the life of your filter by another 4 weeks.

    • Can I throw the filter away?

      That’s up to you! If you choose to discard the filter, be sure to recycle it! The filters are 100% natural and can be reused in the ecosystem. Simply crush it up and sprinkle the granules in your houseplants or garden soil. You can also use the filter as a deodorizer in your fridge, gym bag, or anything smelly!

    • Do I need to replace the filter?

      Only if you want to! Our subscription program makes replacing your filter easy, convenient, and cost-effective. Sign up at and we’ll send a new filter straight to your doors every 2 months.
