Doulton® Water Filter Bottle 790ml

NEW for Summer 2026, the Doulton Water Filter Bottle in two refreshing new colours and increased capacity! Integrating our recently upgraded carbon filter to deliver better-tasting tap water on the go, the new, larger size allows for more time between refills - ensuring cleaner, tastier tap water for longer during all of life's adventures.

Designed with a 790 ml/27.5 oz (with the filter fitted) capacity, this larger size water filter bottle paired with our built-in carbon filter, reduces chlorine, heavy metals and sediment in your tap water for an enhanced taste. The insulated stainless-steel wall also keeps your water cool for up to 24 hours.

Our reusable bottle is BPA-free and reduces your reliance on disposable plastic bottles, making it a more sustainable choice versus buying expensive plastic water bottles when travelling. Not only that, but our new and improved filter also uses 75% less plastic than our previous version. 

Key features:

• New increased capacity of 790 ml/27.5 oz with the filter fitted
• Insulated stainless-steel wall
• Integrated carry handle
• Improved filter to increase flow
• Carbon filter that reduces sediment and more than 95% chlorine and heavy metals*
• Effective filtration for up to 3 months

Available in two all-new colours and with a 790 ml/27.5 oz capacity, the bottle is perfect for on-the-go hydration whether it’s popped into your backpack for a day out, placed on your desk, or for family road trips.
