I’m often a little wary of water bottles with straws because I’ve previously found they become rather unhygienic. This water bottle uses antimicrobial drinking surfaces and a stainless steel telescopic straw, which comes with its own cleaning brush. It’s just as well, since it can’t go in the dishwasher. Helpful review: “I have always had a hard time drinking enough water. Now I have been able to drink 8 cups a day without effort since I started using this water bottle. Having the time markers and only having to fill up the bottle twice a day makes it much easier.”

Baking soda and vinegar. Pair baking soda with white vinegar to effectively clean the inside of your water bottle. Wait for the reaction to finish, rinse out and repeat if necessary. Small design details count, too. Some water bottles come with strainers so that you can add fruit and infuse your drink with fun flavors, and others have positive quotes printed next to the time markings to keep you motivated. Plastic dust caps protect straws and spouts from contamination, and wide mouths are helpful if you want to add ice cubes to your drink. There are also bottles with multiple caps, so you can decide whether to sip from a straw or spout. In terms of portability, water bottles can come with carrying straps, handles on the cap, or handles built directly into the vessel.

It’s no secret that adequate water intake is crucial for good health, but sometimes it’s helpful to have a reminder to stay hydrated. The best water bottles with time markings have the right capacity for your needs and make drinking water feel like less of a chore. There are a few main factors to zero in on when you’re considering your options.

If you are looking for a larger water bottle, the brand offers it in the Hydro Flask Wide Mouth Trail bottles, which come in 32- and 40-ounce sizes. Keep in mind that Hydro Flask recommends that you hand wash all of its water bottles. We've tested 18 reusable bottles from brands such as Bobble, Dopper, Chilly's and S'well to find the best options whether you're hiking, commuting or heading to the gym.BPA stands for Bisphenol A, an industrial chemical compound used in the manufacturing of strong plastics. Some research suggests BPA can leak into food and drink and cause health problems. “When looking for a bottle, look for non-toxic materials. Stainless steel is one of the most eco-friendly materials for a water bottle. Not only is it safe, but it is very durable and infinitely recyclable,” says Natalie Byrne, content marketing manager at Go Outdoors.

Plenty can't go in the dishwasher. But washing them regularly is important to prevent germs building up. Material: There are three main materials used to make reusable water bottles: plastic, glass and stainless steel. Plastic water bottles are usually lightweight and durable, but they can sometimes absorb the flavor of tea or coffee. If cleaned properly, glass water bottles won’t impart any flavor into your water, but they can be delicate or heavy. Stainless steel is a lightweight alternative and is often used for insulated bottles that are great for keeping hot beverages hot and cold beverages cold; they're often not dishwasher-safe. In a departure from the traditional Chilly’s style, this brand new water bottle has a stainless steel straw with a sporty flip lid and carry loop, designed for use on the go. It comes in either 500ml or a litre.First, figure out how much water you aim to drink per day. While the common recommendation is eight 8-ounce glasses, your specific needs can vary depending on different factors, such as the weather and health conditions. The water bottles on my list fall in the range of 24 ounces (which might require at least one trip to the sink or water cooler for a refill) to as much as one gallon. The lip, for me, is well sized. If it’s too large, you risk spilling water all over you clothes; too small and it’s not a comfortable fit for the mouth. Chilly’s is just right. I also find that, while some steel bottles can leave a slight lingering metallic flavour, these ones don’t. I like the textured feel of the bottle, which makes it a little less slippery than some steel options and prevents it feeling too cold or hot to the touch. Water stays hot for a long time – though I’m not sure about the 12 hours claim – and remains cold throughout the day; ideal if you’re on a long walk or a hike. Most companies say they can keep water cold for 24 hours and hot for 12. We wouldn’t recommend keeping water in your bottles any longer than that as it can start to take on a stale taste. That said, you can safely store tap water for up to six months, according to Healthline. Which are the safest water bottles to buy? Its insulated design keeps contents cold for up to 47 hours or hot for up to 14 hours, according to the manufacturer. (If you opt to use this, or any, water bottle for hot beverages, choose a lid with a smaller drinking spout to prevent potential burns. KleanKanteen sells an assortment of compatible lids, including this cafe cap for hot beverages.) Its wide mouth allows for easy filling and cleaning. Plus, it’s dishwasher safe, which is not as common for insulated water bottles. They’re essentially tiny granulate cubes made from natural plant and fruit extracts which are low in calories and free from sugar, artificial flavours and sweeteners. The bottles are made with a perfectly sized drinking hole to drop these cubes inside and flavour the water – hence the name, Waterdrop.
