5 Things to Ask When Choosing a Glass Water Bottle

More and more people are making the switch from plastic bottled water to glass, and it’s easy to see why. Glass is the cleanest choice. Its origins can be traced back to one of the most pure materials—sand. Made for centuries with silica (the main component of sand) glass is simply cleaner, healthier and lasts longer. So whether you’re shopping for a new glass water bottle for the gym or want to tote one around the office all day, keep these questions in mind.

1. What Kind of Glass is it?

While glass can be broken down into several categories, most glassware falls into one of two places: Soda lime glass or Borosilicate glass.

Soda Lime Glass

Soda lime glass is the most common type of glass and accounts for 80% of commercial glass. You see it in windows, jugs, jars, everyday drinking glasses (and just about everything). It’s also the lowest in cost of all glasses.

Borosilicate Glass

While more expensive than soda lime glass, borosilicate glass is more resistant to extreme temperatures. You’ll find it in pyrex dishes, high quality flashlight lens, stage lights, paperweights, beads and ornaments. Want a quick science lesson on borosilicate glass?

What to Look For

Borosilicate glass. While soda lime glass is the most common, that doesn’t make it the best. The Consumer Reports staff performed a year-long investigation between the two and found that soda lime glass cookware breaks more often because it can’t move between extreme temperatures as well as borosilicate. According to the report, “Soda lime glass cookware shatters more frequently because, in theory, it can resist fracture stress as long as the temperature differential is less than about 100°F. In contrast borosilicate glassware can tolerate a differential of about 330°F.” That, obviously, is a big difference.

2. What Material is Lining the Cap?

You’ve picked out your glass water bottle and you’re ready go. Now, take a second and unscrew the cap. Most screw caps have a circular lining that rests along the mouth of the bottle when closed. And, that’s right, it’s typically made of plastic. You may also find plastic along the top of your flip cap, a soft buffer between the mouthpiece and cap of your glass water bottle.

What to Look For

In two words: stainless steel. This is your new best friend when it comes to toxic-free water. What’s the point of a beautiful glass water bottle if it’s lined with plastic where your mouth meets the water? By choosing a stainless steel lining, you’re protecting yourself from BPA and phthalates. Plus, it’s durable. As soon as plastic starts showing any signs of wear and tear, it’s no longer safe. And who are we kidding, this bottle is going to get dropped from time to time.

3. Does it Have a Sleeve?

Speaking of dropping your bottle, it’s important it has the right protection. Shop for a glass water bottle that features a convenient non-slip sleeve. This will give you a secure grip, protect against breakage and prevent heat transfer so your water stays crisp and cool.

What to Look For

A medical-grade silicone sleeve. These sleeves are non-toxic, durable and made from the same component of sand (and glass) we mentioned earlier—silica.

4. Is it as Mobile as You?

It’s important that you can carry your glass water bottle about with ease. Whether that’s slipping it into a gym bag or transferring it to a car cup holder, your bottle needs to travel seamlessly.

What to Look For

A sleek, slim design that’s fit for your busy lifestyle, guaranteeing you’ll stay hydrated from sun up to sundown.

5. What’s its Volume?

Last but not least, it’s important you’re getting enough water each day. There is no real one-size-fits-all approach to water consumption. As a general rule of thumb, men should consume 128 ounces of water daily, and women should consume 88 ounces, but this doesn’t mean you need to drink this amount of water every day. Other beverages, as well as the moisture content of foods, also count toward your water intake. Depending on how active your lifestyle is and how humid your environment is, you’ll need to compensate for the sodium lost in sweat, too.

What to Look For

Whatever size you’re most comfortable with so long as it keeps you hydrated. Many glass water bottles are available in a convenient 21oz and 16oz size. It’s up to you!
