Buying Guide to Insulated Water Bottles

Read our buying guide below to learn about what factors you can consider narrowing down your insulated water bottle options.

Material

Most water bottles are made from plastic, metal, glass, or some combination of the three.

Plastic

Plastic is the lightest and cheapest material but is less durable and insulated. Additionally, it can give your water a plastic taste. There’s also evidence that chemicals from some types of plastic can harm your health. Most water bottles—no matter what their body is made out of—have plastic lids or caps.

Metal

Aluminum and stainless steel are common metals. Metal is more expensive and heavier than plastic but is also more durable. However, some aluminum water bottles can leave behind a metallic taste, especially in water.

Glass

Glass is the heaviest and most expensive water bottle material but is the least likely to leave an aftertaste. Though it can break if you drop it, it’s usually wrapped in silicone or similar material to protect it.

Size

Water bottles range in capacity from about 12 to 64 ounces. Water bottles that hold up to 24 ounces can fit in standard cup holders, such as the ones in your car. Bottles larger than that can’t fit in cup holders, but they give you enough water for most of the day.

Keep the size of the water bottle’s mouth in mind. Wide-mouth bottles are easier to access and clean using a sponge and can easily accommodate large pieces of ice.

Lid

Insulated water bottles can come with screw, flip, spout, or straw lids. If you use your bottle at the gym, at the office, on the hiking trail, and in other situations to hold both hot and cold drinks, choose a water bottle that’s sold with several of these lids. While all the lids work well, straw and flip lids aren’t typically leakproof.

Insulation

How long your water bottle can keep a beverage cold—or warm—is also worth considering. Many insulated water bottles can keep cold drinks cold for up to 24 hours and warm liquids warm for eight to 12 hours. Generally, the thicker the insulation, the longer it’ll keep liquids at your desired temperature.

Cleaning

Some water bottles and their accessories must be hand-washed, while others can go in the top rack of your dishwasher. If you want an easier cleaning process, look for a dishwasher-safe bottle.

Aesthetics

Reusable water bottles come in several colors and patterns. If the aesthetic is important to you, choose a bottle with a design you like.

Frequently Asked Questions About Insulated Water Bottles

Is an insulated water bottle worth it?

Overall, an insulated water bottle is worth the money, especially if you like your water cold and live somewhere hot. Most insulated reusable water bottles keep your drink ice-cold for hours, even in direct sunlight. Vacuum-insulated bottles can also act as a Thermos product, keeping hot liquids or soups warm for several hours in cold temperatures.

Which insulated water bottle keeps water cold the longest?

Although manufacturers may make varying claims about how long their bottles keep drinks cold, all insulated water bottles perform similarly. Any of the high-quality bottles on our list can keep your beverages cold for around 24 hours.

Is it safe to put a lemon wedge in my water?

It’s safe to use lemon wedges in stainless steel and glass bottles. However, the chemicals sometimes found in aluminum and plastic water bottles are more likely to seep into acidic water than plain water. If you like lemon water and prefer aluminum or plastic, look for a BPA-free or resin-lined bottle.

What’s the difference between aluminum and stainless-steel water bottles?

In general, aluminum is lighter and cheaper than stainless steel. In addition to the problem with acidic liquids, aluminum is more likely to give your drinks a metallic taste.
