So why not do your bit and invest in a reusable water bottle.
Not only will it save you money in the long run, carrying a refillable water bottle means you’re more likely to drink the recommended one to two litres of fluid a day.
We put a range of BPA-free water bottles to the test to find the best ones on the market.We put a range of BPA-free water bottles to the test to find the best ones on the market.We put a range of BPA-free water bottles to the test to find the best ones on the market.
We judged them on their leak-proof rating, how good they were at keeping drinks cold and how easy they were to carry – and drink – on the move.
Here’s The Independents pick of the best.
Hydro Flask water bottle: £29.95, Amazon
The insulation on this stainless steel Hydro Flask means it lives up to its claim of keeping drinks cold for 24 hours and hot for 12 hours, making it a hit with all our testers. Holding 620ml, this has a wide mouth so you can pop ice cubes into your drink – perfect on a hot day. It also fits easily in your bag and showed no sign of leaking (even when we were running to catch a train!) We also loved the choice of colours, from bright yellow to baby blue. A great buy if you want a robust bottle for both hot and cold drinks.
Global WAKEcup personalised sustainable bamboo water bottle: £18, Not On The High Street
This bottle came a close second with our testers. Not only does the sustainably sourced bamboo design look great (we had compliments when we pulled it out of our bags in work meetings) 10 per cent of profits go to The Marine Conservation Society and Plastic Oceans.
The bottle – which can be personalised with your name – carries 450ml of water and can be used for hot or cold drinks. We also loved the inner strainer which means you can pop in slices of cucumber or strawberry and make a fruit-infused drink.
Dopper bottle: £12.49, Oxfam
Our testers loved the clever design of the Dopper bottle: either drink from the screw top lid or use the removable cup for your water. The bottle can hold 450ml of liquid and while it has no insulation to keep drinks cold, it’s dishwasher-safe so super easy to keep clean.
Although only usable with cold drinks this bottle is a good – and environmentally-friendly – on-the-go option.
Thermos hydration bottle with meter: £9.99 Amazon
If you want to make sure you’re drinking the recommended six to eight glasses of water a day, this Thermos bottle is a good option. It carries 710ml of liquid and has a handy meter on the side showing you how much you’re drinking (or not).
A handy push button means it’s easy to open and close. The Thermos bottle also showed no signs of leaking even when it was bouncing around in our bags.
Bellabeat spring smart water bottle: £80.88, Amazon
If you like using wearable tech to track everything from your fitness to your sleep, you’ll love this Bellabeat smart water bottle.
All you need to do is download the Bellabeat app and enter your age and activity levels. The app then works out how much you should be drinking each day. The bottle is battery operated so there’s no need to charge it. Simply shake the bottle to sync it and then you’ll get updates on how much you’re drinking and when. We also really liked the option to receive notifications reminding you to have a drink. A really clever piece of wellness tech.
S’well labradorite bottle: £34.99, Zen Wardrobe
Our testers loved the design of this stainless steel S’well bottle. It has double walled insulation which kept our drinks cold (and hot) for hours and the screw top is totally leak-proof.
The bottle can carry 500ml of liquids and fits easily into a bag and is easy to drink from when you’re out and about. A stylish bottle that is built to last.
Sistema tritan traverse water bottle: £8.99, Amazon
This was the biggest bottle we tried, at 850ml and our thirstier testers loved it. With a maximum volume of 850ml, it lasted for hours while we were out and about.
We also really liked the practical design of the bottle. There’s a handy clip on the lid which means it stays attached to the bottle. It doesn’t keep your drinks cold but the bottle mouth is wide enough to drop in ice cubes if you want.
Bio-synergy fruit infuser reusable water bottle: £14.99, Bio-synergy
Plain water can get a little, well, boring after a while. So our testers really liked the 750ml Bio-synergy fruit infuser bottle.
Fill the inner tube with any fruit, herbs or veg you like and then add water. It takes a while for the water to take on the different flavours and the bottle doesn’t keep drinks cold. But it’s easy to use and means you don’t get any pips or random herbs in your teeth while you drink.
Black+Blum eau good glass water bottle: £26.95, Black+Blum
This is a super stylish water bottle which comes with its own charcoal filter made from tree branches. According to Black+Blum, the carbon not only softens tap water it also adds good minerals to your drink. Made from glass, it’s less robust than the other bottles we tested, but it looks really smart and comes with a nifty neoprene sleeve to keep your drink cool.
You have to wait to drink – the charcoal takes a minimum of an hour to filter your water (it tastes even purer if you leave overnight) – but it’s worth it. Our testers agreed this was their favourite reusable bottle for work: fill up using the office tap and then let the charcoal do its thing.
LifeSaver liberty bottle: £89.99, LifeSaver
Our testers were impressed with this Liberty bottle which advertises itself as the world’s only portable water purifier and in-line pump combined. You might not need the advanced filtration technology for your day to day commute. But this bottle comes into its own on camping and hiking trips (or if you’re a Bear Grylls wannabe on the weekend) where the only source of water is a river or lake.
It’s a serious piece of kit: simply fill the bottle with water and the clever filter can remove any nasty bacteria and viruses. We also loved the scavenger hose which means it can be used to fill up other clean water bottles.
Lakeland infuser bottle: £5.99, Lakeland
This was the cheapest bottle we tested and our testers all agreed it’s a total bargain. As with the previous infuser bottle, all you need to do is add fruit to the inner chamber and enjoy any flavour water you like. The chamber keeps the fruit safely stored so no danger of swallowing any random chunks of fruit.
The 500ml bottle is leakproof, easy to clean and is so compact you barely notice it in your bag.
Sistema stainless steel hydrate bottle: £20.03, Amazon
We really liked this Sistema bottle and our testers who preferred drinking from a stainless steel bottle rather than a reusable plastic one voted it as one of their favourites. The bottle can carry 500ml of liquid and is small enough to slot easily into your bag. It comes in a wide range of colours and has got a really nice premium-looking matt finish.
It’s also insulated and kept true to its claims of keeping drinks hot for six hours and cold for 12 hours.
Verdict: Reusable water bottles
Our testers all voted the Hydro Flask as the best reusable water bottle, especially if you want to use it for hot and cold drinks. If you love wellness tech and want a daily record of how much you’re drinking – and when – then the Bellabeat spring water bottle is the one for you.Orginal Source
