Things to Consider When Choosing an Insulated Water Bottle
With so many high quality insulated water bottles on the market today it can be difficult to determine which one will serve your particular needs best. But if you keep the following considerations in mind it should help you winnow down your choices.
Size/Capacity – If you’re a hunter pursuing a 12 point buck across the high country you’re not going to want to be lugging around the Under Armour 64 oz bottle. You’ll need something more compact but with enough volume to keep you hydrated. Something like a 24 or 32 oz bottle. If your bottle will be doing yeoman’s work at the beach with the kids you may want that UA behemoth.
Materials – Any insulated water bottle worth buying these days is BPA free and fashioned from high grade stainless steel. It should be double-walled with a vacuum between those walls that effectively blocks heat transfer. If the bottle has a particular color to it that color should be a powder-coat and not simply a layer of paint that could scratch or wear off. Textured finishes are also desirable for those who want to access their fluids on the move.
Shape – If you want to take 18 oz of ice cold water along with you on your bike ride it’s important that the insulated bottle be sleek and light so it can tuck away easily and be handled with surety while you’re on the move. On the other hand if your bottle will be spending most of the time in the car on long drives just about any old shape will do.
The Lid – If you think you’ll be using the insulated water bottle while you’re on the move it’s important that you have a lid with a narrow mouthpiece, perhaps even a straw-like mouthpiece. The lid also needs to be absolutely leak proof. In 2018 there’s simply no excuse for anything less. You might want to consider something like the Flow bottle profiled above which comes with 3 different lids.
Performance – Any well-made insulated water bottle today will keep your drinks nice and cold for up to 24 hours. Some even longer. When it comes to keeping things hot it’s a bit trickier and effective times range from 6 to 12 hours among the best insulated bottles. If keeping things hot is important to you you’ll need to keep your eyes open and don’t select a bottle that will only do so for 6 hours or less.
What is BPA? – Bisphenol A is an organic compound used to create many types of polycarbonate plastic. Polycarbonate plastics in turn are often used in the creation of water bottles. In recent years the NIH (2) and others have raised concerns about the possible health risks of BPA primarily in regards to fetal exposure. It is believed by many that BPA may negatively affect the brain, reproductive organs and behavior of newborns and perhaps contribute to the onset of early puberty in girls. Needless to say you don’t want your water bottle to contain BPA.
What makes this type of bottle “eco-friendly”? – Many insulated water bottles today use recycled materials in their construction. But beyond that the fact that your insulated water bottle will last for years means you are no longer one of the billions who add countless plastic water bottles to the world’s trash crisis every day. And when it’s time for a new insulated bottle your old one can be 100% recycled in most cases.
How does an insulated bottle keep water cold? – The insulated water bottle has two layers of stainless steel under the shell. In between these layers is a vacuum and on the inside is a reflective material. In addition, they sport a screw down lid that effectively seals the top. The vacuum stops the inward and outward conduction of heat, the screw down lid prevents air infiltration that could create convection and the reflective lining prevents radiation (meaning the loss of radiant heat). Together these three elements leave no way for heat to infiltrate or escape.
Can I take an insulated water bottle on an airplane? – In most cases, yes. You will likely have to empty your bottle before going through security and the bottle itself will need to be scanned. But most modern airports will have bottle filling stations in the boarding area where you can refill with reasonably clean water.
What’s the best way to clean an insulated water bottle? – Even if you only use it for water it’s still a good idea to clean your insulated bottle from time to time. Doing so is not hard, just follow these steps:
- Remove the cap and put 2 tablespoons of vinegar into the bottle.
- Put the cap back on and shake the bottle vigorously for 15 to 20 seconds.
- Remove the cap and, without emptying the vinegar, fill the bottle about ⅓ of the way with spring or filtered water.
- Use a bottle brush to lightly scrub the inside with this mix.
- Put the cap back on and shake vigorously for another 10 seconds.
- Remove the cap, empty the contents and rinse the bottle thoroughly using clean water.
Today’s insulated water bottle is a common sense piece of everyday kit that will help you lead a healthier, more environmentally friendly life.
