10 Best Water Bottles With Filters UK 2023 | LifeStraw, Brita and More

Perhaps the most important factor when it comes to choosing your new bottle is the size and how much water it can hold. If you’re going to be travelling around, you’ll want something portable that holds enough water to quench your thirst but won’t weigh you down in the process. Smaller bottles of around 500-650 ml are light enough to use as a travel bottle.

However, if you’re looking for something to keep at your desk then the capacity can be as large as you like! Some of the options on our list of recommendations include bottles with a capacity of 800 ml or even 1000 ml, so you'll only have to refill them a couple of times during the day.

All of our recommendations provide a minimum of 50 litres’ worth of filtered water, which equates to roughly 250 cups. Many of our picks will last much longer – those with a usage limit of 150 litres will provide approximately 630 cups and those with a usage limit of 1000 litres will yield over 4000 cups!

So, whilst filter bottles with a higher usage limit may seem expensive at first, it’s worth bearing in mind that they’ll be very cost-effective over time.
