Waterdrop is fast joining the top names in the booming water bottle industry, with ambassadors including tennis stars Novak Djokovic and Taylor Fritz (Djokovic having reportedly made a fairly sizeable investment in the company). In such a saturated market, Waterdrop has come up with something slightly different to stand out: Microdrink cubes. The body curves inwards around three quarters of the way up so you can wrap the rest of the hand around the body as you press the lid. I’d suggest it really needs to be a little higher, though I do have small hands. Yet another shopper found that this brand also offers friendly and prompt customer service. She shares in her Ocean Bottle review: “The awareness it raised helps spreading word and getting more people to support the cause to save our oceans. The people at Ocean Bottle are very nice and helpful with query one may have.”

Tossed into lakes and rivers, these plastics eventually enter the ocean where they ruin marine ecosystems – that’s where Ocean Bottle comes in! Many brands will also be certified by industry-recognised sustainability charities. Some logos to look out for include B-Corp, signifying the business puts purpose before profit; 1% for the Planet, meaning the organisation donates 1 per cent of its revenue to environmental causes each year; and also Climate Neutral, a globally-recognised standard for carbon accountability.Owning a reusable water bottle is a statement in its own right – a declaration that you are doing your bit for the planet. But where to start? Today the options are endless, with some offering vacuum insulation to keep their contents cold or hot, some ergonomically designed for your workout or daily commute, and others better suited to sit proudly atop your desk.

Binchotan Charcoal (also used in high-end barbecuing) not only filters out impurities like chemicals and metals but also imparts healthy minerals like potassium. Tangibly, this means tap water is eradicated of bad smells and tastes like bottled water. It takes around eight hours to do so, meaning you’ll get the best results filling it the night before. I didn’t have a 2L pop bottle on hand, so we used an empty mouthwash bottle. I like that the lid is child-safe, and too challenging for little hands to twist open. If you’re using a bottle that’s not child-safe, you might want to run a little hot-glue around the inside of the bottle lid. Another customer loves Ocean Bottle’s charitable impact on marine life and coastal towns, reporting in her Ocean Bottle review: “A brilliant solution for the plastic and poverty problems. Smart design, minimalist aesthetics, versatile use. Beautiful, lightweight and practical.” S’wheat is the most environmentally friendly reusable water bottle, because it is made from biodegradable plant-based materials, bamboo and wheat straw, which would otherwise have been agricultural waste. The company also plants a tree with every sale, takes plastic out of the oceans and donates a percentage of its profit to protect sea life. Another customer says she is appreciative of this company’s commitment to saving ocean ecosystems. She shares in her Ocean Bottle review: “ The thing I love the most about your product is that you’re motivating people to take care of the ocean.”I loveto make homemade toys for the hooligans. Discovery bottlesare always a favourite here. They look so beautiful, and no matter what we fill them with.

Now, simply top up the bottle with oil. I filled ours right to the top and then popped the lid on. Let the fun begin! Some water bottles are dishwasher safe but it is still important to clean the smaller parts with a toothbrush or bottle brush, especially those with built-in straws. If not washed properly, bacteria like E. Coli can grow inside water bottles and lead to gastroenteritis. Mould can also start forming in unwashed bottles. How long can you keep water in a reusable water bottle?

Warm soapy water and a bottle brush will clean all sorts of water bottles including metal, glass and plastic. I recommend that you use fragrance-free soap, as bottles made of silicone and plastic can take on the scent of the soap. For straws, use a pipe cleaner. If a straw is removable, soak the straw at least once a week,” says Byrne.
