7 Best reusable water bottles for the eco friendly scuba diver

A sea of plastic – save our coral reefs – ditch single-use plastics

Watching the world change rapidly before my eyes, I frequently ask what part do I play in the changes? I realize my actions make a difference to me, my community, and the world. I may not always get it right, but on my journey to being an eco-friendly senior scuba diver, I intend to live my life as sustainably as possible.

One of the easiest ways to accomplish my sustainability goals is to reuse items. A water bottle is a prime example. In America alone, 50 billion water bottles are purchased every year. One person changing to a reusable bottle from a plastic bottle saves 157 bottles from entering our landfills and oceans. Australia’s bottled water industry alone generates 60,000 tons of greenhouse gas emissions every year, the equivalent of 13 000 cars! It gets worse!!

The damage the bottled water industry is doing to our planet just to satisfy our consumerism and need for convenience horrifies me. It takes 17 million barrels of oil to make one year’s supply of bottled water. That much oil could fuel 1.3 million cars annually or power 190,000 homes. As a scuba woman, I want to put an end to plastic.

The plastic problem can be overwhelming, but we can all make a difference with simple choices. A water bottle that is reusable, recyclable, and ethically manufactured with sustainable packaging is a simple way to combat the negligence of the bottled water industry.

7 Best reusable water bottles for the eco-friendly scuba diver

Consider your needs when buying a reusable bottle and where and how you will use it. Non-insulated water bottles tend to be lighter to carry than insulated water bottles. Obviously, insulated bottles will keep your water cold and coffee hot, but for how long? Do you want room for ice, a wide mouth or narrow mouth, with a carry strap or without? What size would you like? Does it need to be leakproof, functional or fashionable, or both? Most importantly, do you want a reusable water bottle to do good for the environment?

Fortunately, I have found the 7 best reusable bottle brands that are eco-friendly and practice sustainability.

What is the best reusable bottle brand?

As a senior scuba diver, I champion small companies producing eco-responsible products and protecting our aquatic environment. I support eco-friendly and zero-waste businesses that are advocating for our wonderful planet. I have chosen what I believe to be the 7 best reusable bottle brands. The brands below make stylish, high-quality reusable water bottles and are aware of their environmental impact. They are also giving back to improve our planet.
Scuba women can take steps to live sustainably by our choices as consumers. With the average person creating 400kg of waste yearly, consider refusing, reducing, reusing, recycling, and only replacing when necessary. Reducing waste is an excellent place to start on your journey to being an eco-friendly consumer. Reusable water bottles are one of the easiest ways to lessen waste.

How to clean your reusable water bottle the eco-friendly way

To keep your reusable water bottle clean, fill the bottle with hot water and add a few drops of an environmentally friendly detergent; pop the cap on and give it a good shake. Rinse with water to remove any residual detergent and rinse with warm water. Alternatively, use a mixture of 1 teaspoon of baking soda and water. Pay specific attention to the spout or straw, and don’t forget the outside, base, and around the rim of the lid. Always read the care instructions and rinse and wash your water bottle after each use to prevent the growth of bacteria.

Unless otherwise stated, wash vacuum-insulated stainless steel bottles by hand. If your bottles retain the odor of a favorite drink, simply soak them with a mixture of 1/3 vinegar, 2/3 water, and 1 tsp baking soda and rinse thoroughly.

With love for our oceans, each company has taken action to address environmental issues that affect us all—creating eco-friendly, zero-waste, recycled, and sustainable products. They know their fin print on our world and choose to do the right thing as best as possible. Significant changes often start with minor changes. Even if you haven’t already, switch to a reusable water bottle.
