I've got a confession to make: I never drink enough water. But the simplest way I've found to combat this is by investing in a bottle that I look forward to using, and I know will keep my water in the best possible state - think chilled, filtered, and fresh. Enter: the best smart water bottles that deliver on all of the above, plus advanced syncing with fitness trackers and apps where needed.

I know I'm not the only one who struggles with my water intake on a daily basis. In fact, research by hydration brand air up® found that more than 389,000 Brits spend more than £100 a month on hydration products but report not feeling the benefits. Additionally, 22% of 18-24-year-olds report feeling constantly dehydrated throughout the day. That's why finding a water bottle that can help with habit tracking and making hydration as simple as possible is so important.

This becomes even more pertinent if you're someone who spends a lot of your week being active. That's why I've sought the recommendations of fitness and wellbeing experts who rely on appropriate water intake day in, day out.

Alongside trying out the biggest 2026 wellness trends and wellness journalling to keep you on track with drinking water, habit stacking - like attaching hydration to a habit you're already used to - is a surefire way to get more water in your system. But to make the process even easier and more effective, investing in a smart water bottle could be the way to go. Be sure not to miss our guide to the best electrolytes, while you're at it.

Not the most stylish design

I got this BRITA bottle as a gift for Christmas and it is exactly what I'd been needing. I've had filtered water jugs at home before, but I'd always end up filling up my bottle from the tap in a rush or leave the house with my bottle completely empty. Not only is this water bottle so lightweight, but it filters on the go so requires zero prep on my part. It's the ideal design for using when exercising, and it can go through the dishwasher for easy cleaning. Yes, you have to buy new filters when needed, but it's well worth the small cost considering this bottle reduces chlorine, other taste impairing substances such as pesticides, herbicides and hormones and microparticles.

LARQ is one of the top rated smart bottles on the market, and it has some of the most advanced technology a bottle can have - including a self-cleaning feature, app compatibility for habit tracking, and the ability to keep your water cold. It eliminates 99% of bio-contaminants such as E. coli and mould from your water and bottle using the patented PureVis UV-C LED that activates every 2 hours. "The fact that I have quality, clean water anywhere I go is a huge relief, as I am very health conscious. The water in the bottle is pleasingly cold, tracking helps me keep tabs on my hydration and to clean the sipping part on top I simply pour boiling water over the mouthpiece, to kill any bacteria there. I have recommended LARQ to countless friends now," says one reviewer.
