Eco Vessel FAQs

Very easily.  We recommend warm, soapy water and air drying.  If you feel that your bottle needs a more thorough cleaning, wash it with diluted vinegar or baking soda and water.  Please do not use bleach or chlorine cleansers since the naturally protective finish of stainless steel, while very durable, can be damaged by these ingredients. 

Can I Put My Eco Vessel In A Microwave?

No! Stainless steel bottles are not microwave safe. 

Can I Put Hot Liquids In My Eco Vessel?

You can pour hot liquids only into our insulated bottles since filling a non-insulated bottle with a hot beverage will cause the exterior to become hot and could result in a burn. Even when using our insulated model, you need to take care when pouring any hot liquid and do not overfill.

What Types Of Beverages Can I Put In My Eco Vessel?

Just about anything, from water to juice to chocolate milk, to gin or beer.  With our insulated model, you can fill it with any hot beverage such as coffee, tea, hot chocolate, soup, etc.

Where Are Your Bottles Made?

With the exception of some parts, our bottles are manufactured in China.  The drinking spout of the sippy bottle is made in England and the filter for our Aqua Vessel Insulated Filter Bottle is made in the United States. Because this is the most common question we get, we would like you to understand the situation. We do not know of any stainless steel bottle that is manufactured in the U.S. or in any other country other than China. Having said that, we use very responsible facilities where there is respect for the workers and the environment.  We visit them on a regular basis to ensure their compliance with our high standards. All of our bottles are made with premium quality, food grade stainless steel - the same kind many people use for eating and cooking. 

Do Your Products Contain Lead, Phthalates, BPA, Or Other Harmful Material?

No.  All of our products are made without the use of harmful or leaching materials and chemicals. Further, because stainless steel is proven to be such a safe material, there is no liner or coating on the inside of any of our stainless steel water bottles.  The silicone used to create the collapsible lunchbox and the spouts on our straw bottles is made from food grade silicone, a compound of the elements silicon, hydrogen, oxygen, and carbon. The Scout, Frost and Wave bottles use a TPR spout that is kid-safe and eco-friendly. Any plastic that we use (for instance, the lid and Sport Flo tops) is 100% recyclable and free of all leaching materials.  What is TPR?  TPR stands for for Thermoplastic Rubber (also known as Thermoplastic Elastomer, or TPE).  It is a mix of rubber and plastic polymers that is highly resistant to biting, chewing, heat, and bending.  Like silicone and stainless steel, TPR is recyclable and does not contain leaching chemicals that would contaminate your water.  It is often used in medicinal practices to make catheters, and is also used in home, auto, and electrical products as insulation.  We chose it as the spout for our Kids' Straw Bottles not only for its properties of safety, but also for its durability.
