The Healthiest Water Bottles for you & the Planet!

Not only are single-use water bottles bad for the environment, but they’re also incredibly bad for your health. The BPA found in many water bottles has been linked with cancers, infertility, and even birth defects. And that’s just the tip of the iceberg.

Chances are, you already know you should be using a reusable water bottle. But maybe you’re stuck on which one to choose. Health should always be a contributing factor when we make decisions about what goes into our bodies, so to help you make the right choice, we’ve rounded up the healthiest water bottles on the market today.

Why use reusable water bottles?

Over 60 million plastic water bottles are thrown away in America every single day. They clog up landfills, pollute rivers, and litter parks. A plastic water bottle can only be used once before it becomes an environmental concern.

Many of us are turning to reusable bottles to do our part in the fight against climate change. These bottles can be filled at home and used over and over. A good reusable bottle can last for years without needing replacement.

But besides the environmental concerns, there are many other advantages to reusable bottles.

Temperature control, durability, and built-in water filtration are all features that can be found in reusable water bottles.

The best reusable water bottles do carry a larger price tag, but over time they more than make up the cost. 

Perhaps the greatest personal advantage is for your own health. Plastic water bottles break down incrementally as you use them.

This allows small microplastics to make their way into your drinking water. While you won’t smell or taste them, the chemicals can cause damage that sometimes won’t show up until years after you’ve ingested them.

To save money, save the environment, and benefit your overall health, we’ve rounded up the best and healthiest options for reusable water bottles.

Frequently Asked Questions

Still have questions about how to choose the healthiest water bottle? We’ve answered some of your most commonly asked questions below.

What is the best material for water bottles?

Stainless steel and glass are the healthiest materials for a water bottle. Glass water bottles are chemical-free, natural, recyclable, and easy to clean. Glass bottles are also non-permeable, so they won’t break down into the water, affecting taste and your health.

Stainless steel is another good option. It doesn’t contain chemicals that will be imparted into the water, making it safer. It’s also durable, and easy to clean. Stainless steel works well for insulation and it doesn’t harbor bacteria the way that plastic water bottles can.

How often should you wash your water bottle?

You should clean a reusable water bottle after every use. Think of it as a plate, or cutlery. It needs to be cleaned after coming into contact with beverages.

For a daily clean, use hot water and soap. Take special care around the opening, as this has nooks and crannies where germs can collect. Then let it air dry completely.

Some reusable water bottles are dishwasher safe, but be sure to check. Putting a non-dishwasher safe bottle in the dishwasher can ruin its seal or damage it in other ways.

About once a week, you may want to deep clean your water bottle.

How to deep clean a reusable water bottle?

To deep clean a reusable bottle you can use vinegar for an eco-friendly solution. To clean with vinegar, fill the bottle halfway with equal parts water and vinegar. Secure the top, and shake well. Leave the bottle to soak overnight. The next morning, rinse thoroughly with warm water.
