FAQ

Are your copper water bottles made of pure copper?

All of our copper water bottles are made of 100% pure high-grade food-safe copper. We don’t use any other metals, alloys or lining. All of our copper water bottles are of exceptional quality.

We are sorry to say that many other sellers (particularly those who sell on Amazon and Ebay and manufacture their copper bottles in China and India) falsely claim to sell pure copper water bottles that are actually plain metal bottles plated with copper. The copper plating will start to rub off these bottles after only a few months of use. Many of our customers came to us and bought one of our pure copper water bottles after having a bad experience with one of these sellers. While these sellers are able to offer their bottles for sale at a lower price than our bottles, beware – they are not the real thing!

In addition, many other sellers are selling copper bottles that are coated on the interior with a lacquer that is toxic and should definitely not be in your drinking water! Our copper bottles are pure and contain absolutely no toxic materials of any kind.

We are also sorry to say that many other manufactures do not construct their copper water bottles to the same level of quality that we do. As a result, some customers have reported that copper shards have peeled off the inner surface of copper bottles that they bought from other sellers, with those shards ending up in their drinking water!

Please make sure to do you research and invest in a quality copper bottle. Read more in this guide to ensure that you are getting the best copper vessel.

Do you sell through any online marketplaces?

We do not sell through any online marketplaces such as Amazon or Ebay. We are sorry to say that many sellers on Amazon and Ebay falsely claim to sell Copper H2O bottles. You can purchase our bottles exclusively online through our website www.copperh2o.com. Please contact us if you find a listing claiming to sell Copper H2O bottles.

Can I get too much copper if I drink from my copper water bottle all the time?

Although the concept of storing water in copper vessels arose centuries ago and has its origins in Ayurvedic medicine, it is increasingly gaining attention from the mainstream scientific community. In several recent scientific studies, it was determined not only that water stored in a copper vessel can have practical benefits.

In addition, recent studies note that the World Health Organization has concluded that it is safe for the body to consume up to 2mg of copper per litre of water. Research also shows that the water stored in the copper vessel for several hours absorbed less than 1/20th of that amount of copper, which is very far below safe limits.

Nevertheless, we recommend using your copper water bottle in moderation and not storing the same water in it for more than 6 to 8 hours.

Can my copper water bottle create alkaline water?

Storing water in your copper water bottle is a great way to make natural alkaline water. In fact, our copper water bottles are essentially natural alkaline water bottles. Drinking alkaline water can be a great way to support a healthy lifestyle.

Check out our blog post for a detailed discussion that introduces alkaline water, explains the benefits of alkaline water, identifies the important differences between natural alkaline water and artificial alkaline water, and shares how you can make natural alkaline water easily, safely and inexpensively using your copper water bottle.

To help our customers, we have also made this short instructional video to explain how to make alkaline water with your copper water bottle:


How long does it take to create alkaline water?

Water stored in a copper vessel will become increasingly alkaline the longer it remains in the copper vessel, and the speed and degree of the alkalinization process will depend on various environmental factors, including the temperature of the water and its original pH level. In general, the natural alkalinization process will occur a bit faster if the water is at room temperature or slightly warmer. In general, we suggest storing water in your copper water bottle for 6-8 hours for the most beneficial effect.

What does water stored in a copper bottle taste like?

It tastes great – fresh, clean and pure! Although some people expect the water to taste metallic, it does not. Water stored in a copper bottle will absorb the beneficial health quantities of copper, but it doesn't absorb enough copper to dramatically change the taste of the water. You may detect a slight hint of copper if your tongue touches the bottle as you drink from it.

What type of water should I use in my copper water bottle?

You can use any type of water in your copper water bottle, including tap water, water that has been passed through a filter, or even bottled water. You will probably notice the greatest difference with tap water, which is generally the least alkaline and in the need of the most care. Although tap water is generally fine in most first-world cities, you may wish to consider filtering your water before pouring it into your copper water bottle.

Should I clean my copper water bottle before using it for the first time?

Your copper water bottle will be ready to keep you hydrated as soon as it arrives, but we do recommend washing the inside with warm water and a drop of liquid soap before filling it up with drinking water for the first time.

How do I polish and clean my copper bottle?

Easy! Your copper water bottle is made of 100% pure copper, so it will naturally patina over time. Many of our customers like having the exterior of their bottles age gracefully into a beautiful copper patina, but, if you prefer the shine of copper, it is very easy to remove. Simply sprinkle a pinch of salt on a slice of lemon, allow the salt to dissolve, and then gently rub it on the surface of your bottle. The lemon and salt will form a mixture that will naturally remove the patina and restore the copper’s shine. Once done, rinse with water and dry well.

To help our customers, we made the following short instructional video to demonstrate how to clean your copper water bottle with lemon and salt:


The inside of the copper water bottle will also patina, but this does not impair the water stored inside the bottle. We recommend cleaning the inside of your bottle every now and then with warm water and a drop of liquid soap, and then rinsing it well. However, be sure to never wash your copper water bottle in a dishwasher.

We also made the following short instructional video to demonstrate how to clean the inside of your copper water bottle with lemon and salt:

Is it leak-free?

Each of our copper water bottles is capped with a leak-proof cap. You can throw this bottle into your favorite bag with confidence that it will stay water-tight!

Can I use lemon or other fruit with my copper bottle?

There are plenty of benefits of drinking lemon water and other infused water and so it's a great idea to combine those benefits with the benefits of water stored in a copper water bottle. To get the greatest health benefits, try to combine water from your copper water bottle with lemon slices or lemon juice in a cup. Copper can react with certain acids, including citric acid found in lemons, so it's best to only use water in your copper water bottle. 

Can I use coffee, tea, juice, or sparkling water in my copper bottle?

Because copper can react with acidic liquids (anything with a pH of less than 7), we recommend only using water in your copper water bottle.

Can I use essential oils with my copper water bottle?

While we don't recommend adding essential oils directing into your copper water bottle (as certain very acidic essential oils can react with the copper), you can certainly add essential oils to your copper-charged water in a separate container.

Can I use crystals with my copper bottle?

Yes, you can use easily and inexpensively use crystals in conjunction with your copper water bottle. Read our blog post on the subject to learn how to make your own crystal water bottle or 'crystal elixir'.

Will your copper bottles fit a car cup holder?

Yes, both sizes of our copper water bottles fit in a standard-sized car cup holder.

Are your copper water bottles handmade?

Yes, all of our copper water bottles are handmade by skilled artisans using traditional methods. As a result, every bottle will be unique and may have some imperfections which add to the character of the piece.

Why are your copper water bottles hammered?

Our copper water bottles are hammered by hand using traditional methods for two important reasons: to create a gorgeous aesthetic, and to increase the surface area of copper on the inside of the copper water bottle which makes contact with the water stored in it. The greater the physical contact between the water and the copper, the greater the health benefits for you.

We now also offer smooth bottles for those that prefer that aesthetic.

Are your copper water bottles lined?

Our bottles are made from 100% copper and do not have any sort of lining.

Do your copper bottles have a lacquer coating?

Our copper bottles are pure and do not have a lacquer coating on the interior.

If you see a copper bottle that does not develop a patina on the interior over time, it is likely coated in toxic lacquer. Many other sellers are selling copper bottles that are coated on the interior with a lacquer that is toxic and should not be in contact with your drinking water.

We do use a special non-toxic coating on the exterior of our smooth brushed bottles only for those customers who are looking for a bottle that does not develop a patina on the exterior as quickly as our other bottles. None of our bottles have any sort of coating on the interior, which ensures that your water comes into contact with pure copper only.

Do you make double-walled or insulated copper bottles?

We specifically choose not to make double-walled or insulated copper bottles, and there are two very important reasons why.

There are only two reasons to use a double-walled or insulated bottle: to keep water cold, or to keep it hot. When it comes to cold water, Ayurveda recommends drinking room temperature or lukewarm water rather than cold water as doing so can literally douse the digestive fire that builds up in our bodies. In addition, drinking cold water can freeze the enzymes in our gut, which can prevent our bodies from properly digesting food, which can in turn increase the amount of toxins in our bodies.

In addition, drinking cold water can cause a contraction of blood vessels, which can further increase the likelihood that toxins will remain inside your body rather than being excreted through your lymphatic system.

Conversely, drinking room temperature or lukewarm water supports the lymphatic system, which means that, over time, more toxins will be expelled from the body. In particular, drinking room temperature or lukewarm water flushes the lymphatic system, helps soften hardened tissues, dilates, cleans and hydrated deep issues, and heals and repair the digestive system.

While it is fine to fill your copper water bottle with warm water, we recommend against filling it with hot or boiling water, as this can negatively affect your bottle and potentially cause the water to absorb too much copper from your bottle (the greater the temperature of water, the more capable it is of absorbing metals such as copper).

Accordingly, because the healthiest approach is to drink room temperature or lukewarm water, we do not make double-walled or insulated copper bottles. In addition, double-walled copper bottles can be prone to very significant problems. Copper is a very soft metal, and, based on construction methods used to make copper bottles, water stored in double-walled bottles will eventually seep in between the two walls and, unbeknownst to you, lead to the formation of mold which can be very detrimental to your health. We specifically choose to produce our bottles with a single wall to avoid that problem.

Can I put my bottle in the refrigerator or freezer?

You can store your bottle in the fridge if desired (keeping in mind that it is best to drink room temperature water as mentioned above), however you should never place your copper bottle in the freezer as it could explode.

Is your logo or company name stamped anywhere on your copper bottles?

As proponents of product minimalism, we are happy to say that our copper water bottles are not stamped or marked with logos or text of any kind. We've worked hard to offer a beautiful and unique product with a minimalist design because we believe that products should be designed to complement your unique personal style. Each of our copper water bottles is a unique handmade creation, and we want each of our customers to make their copper water bottles their own. In short, we don't want to turn you and your copper bottle into a walking billboard!

What are the dimensions and weights of your copper water bottles?

Our 20 oz / 600 mL copper water bottles are approximately 9 inches in height, 2.5 inches in diameter, have an opening of 1.75 inches, and weigh approximately 0.42 lb / 0.19 kg.

Our 30 oz / 900 mL copper water bottles are approximately 10 inches in height, 2.75 inches in diameter, have an opening of 2.25 inches, and weigh approximately 0.57 lb / 0.26 kg.
