When it comes to how much water you need to drink to stay properly hydrated, we’ve all heard the eight glasses a day mantra. But the truth is there is no one-size-fits-all number—daily water intake requirements vary from person to person and depend on factors like size, activity level, metabolism, climate, medications, and more.

While the recommended daily intake looks different from person to person, one thing we can all agree on is that hydrating daily is essential to our overall health. Investing in a reusable water bottle that fits your hydration needs and style is the logical next step. Just as a pair of new leggings can motivate you to get to the gym, a new water bottle is sure to update your hydration game.

What to Look for in a Water Bottle

Material

The most popular water bottles are constructed from three primary materials—plastic, stainless steel, and glass. Plastic water bottles are usually affordable, lightweight, and portable. Most plastic water bottles on the market today are made from Tritan, a rock-hard plastic material that's BPA-, BPS-, and BPF-free. These hard plastic bottles look like glass yet are very difficult to break. Tritan is also dishwasher-safe.

Stainless steel bottles offer insulation, keeping beverages at their respective temperatures for long periods of time. Bottles with double- and triple-walled insulation can even keep beverages hot or cold for upwards of 24 hours. This feature tends to make stainless steel bottles a bit heavier than plastic ones.

Glass bottles are less likely to alter the taste of your water or leave any residue. The downside is that glass is heavy and highly breakable. Many glass water bottles come in fashion-forward designs and are often sold at higher price points. 

Capacity

Choosing the right bottle size depends on your personal water intake needs, as well as your activity level. It's also up to your personal preference and whether you prefer to fill up a big water bottle in the morning and be done for the day or have a smaller, more portable bottle that you can refill throughout the day.

Lid Design

Water bottles come with varying styles of lids, with the most popular being screw-on, flip-top—often containing a straw-like spout—and sport nozzles. Lids offer convenience for different activities, which is why some athletes prefer a sports nozzle for a quick squirt of hydration during games.

FAQs

What is the best water bottle material?

Water bottles come in stainless steel, plastic, or glass options. Picking one material over another isn't an easy decision as there are pros and cons to owning each.

Stainless steel bottles are corrosion-resistant and do not leach chemicals when exposed to the sun. As a result, they last longer than ones made of glass or plastic. Stainless steel is also 100-percent recyclable.

Most of us know that drinks taste better in glass water bottles. However, glass is breakable, making its lifetime much shorter than stainless steel or plastic options. The recycling rate is low, and some public places do not accept glass for recycling. Like stainless steel options, glass bottles also offer the benefit of not leaching chemicals when left in the sun or heat. However, the price of a glass water bottle is typically much higher than that of the other two most popular options.

While glass and stainless steel are gaining popularity, plastic is still the most popular reusable water bottle material. The primary appeal of plastic water bottles is that they tend to be a lot less expensive than other options. However, plastic isn't an environmentally-friendly material—the recycling rate is low, with bottles ending up in landfills. Plastic water bottles also tend to leach chemicals when exposed to the sun, whereas glass and stainless steel do not. 

How many bottles of water should I drink a day?

For your body to function optimally, you must replenish its water supply daily by drinking beverages and consuming foods that contain water.

Since each individual has different needs, there is no definitive answer. The National Academies of Science, Engineering and Medicine recommendations set adequate daily water intake levels from all foods and liquids at 3.7 liters (125 ounces) for men and 2.7 liters (91 ounces) for women.

How do you clean a water bottle?

After each use, wash your bottle in hot water with a teaspoon of unscented dish soap. Let it soak for a few minutes, rinsing it well with warm water, and allow it to dry completely.

If the bottle is dishwasher-safe, run it through your dishwasher, thoroughly cleaning and sanitizing.  

A few times each week, use a weak bleach solution of 1 tablespoon of bleach per quart of water to sanitize the bottle. Avoid using too much bleach as it will leave an unpleasant taste in the bottle.

Don't leave water in the bottle for long periods between each use. Empty the bottle when you finish using it each day.
