Do you see various types of bottles in markets and face confusion when choosing the right one? Actually, we want to figure out the time one can spend to select the best bottle based on its material. Don’t you believe that I have spent several nights searching for the best bottle based on materials? Well, it is true and I really faced a difficult time when searching the top water bottles for daily use. This intensive time period; however, brought me a special set of information related to water bottles and materials being used to produce them.

Reusable Plastic Bottles:

First of all, it is important to talk about reusable plastic bottles as these are commonly used with high preference. These are available in wide range of sizes, shapes, and colors. These bottles are everywhere. Easy availability of plastic water bottles makes them more attractive to buyers. Reusable plastic bottles seem to win the battle of reusable water bottles. However, recent studies and experiments are no longer in favor of these bottles.

The biggest reason behind the latest opposition is the presence of BPA. This is among the most dangerous elements used to produce plastic bottles. BPA has proven effects on health such as carcinogenic effects. This is why experts don’t recommend the use of reusable plastic bottles. On the other hand, these bottles are also creating pollution in our oceans and lands. It is because of the inability to recycle all the plastic bottles produced in the world. According to authentic reports, only 23 % of the total reusable plastic bottles are recycled every year. What about the remaining 77 %? All these water bottles go to oceans and landfills where these cause pollution.

Reusable plastic bottles are not a good choice if you love the environment and your health. As there are proven negative impacts of reusable plastic bottles so it is recommended to avoid this choice. You can switch to alternative options such as eco-friendly water bottles. This will keep your health and environment safe from the negative effects of BPA and other toxins.


What about Plastic Numbers (Grades)?

Reusable plastic bottles contain a special number which shows the plastic grade used to design them. Here are details of some commonly used plastic numbers.

Plastic #1: This is the first-grade plastic which is also called PET. This plastic is considered safe for common utilization. A common example of plastic #1 or PET bottles is Aquafina or Dasani. Most people consider them reusable water bottles and they keep using them after washing. No doubt, the chances of toxin leaching in these bottles are lower but there is no way to clean the bacteria properly. This is why plastic #1 is not a healthy choice for reusing.

Plastic #3, #6 or #7:

In other words, these water bottles are PVC bottles. These are dangerous for health. Numerous scientific studies confirmed that toxins leach down in the water in these bottles. This is why there are several negative health impacts on the people who use these water bottles. The most common health issues include reproductive damages and development issues. The plastic #7 is also called poly-carbonate. This type of plastic is not usable for food storage. No doubt, this plastic type or grade is durable but it is still risky for the consumers. Recently, BPA-free plastic #7 bottles have been introduced. However, it is essential to choose healthier alternatives especially when you have lots of choices.

Plastic #2, 4 or 5:

These are healthiest options so far. However, these bottles have several other issues. They will retain the odor and stains if used repeatedly. On the other hand, water bottles designed with these plastic grades are not durable. This makes them a short term choice. Washing these bottles in a dishwasher is not possible. The only positive feature of plastic #2 is the excellent ability of recycling.


  • Cheapest choice.

  • A wide range of colors, sizes, and shapes.

  • No metallic taste in the fluids.

  • Easy to clean.


  • Most contain BPA.

  • Conflict of interest in the presence of toxins is present.


Stainless Steel Water Bottles:

These water bottles are designed with the help of special metals. Stainless steel is a non-reactive metal which enables the manufacturers to create a wide range of sizes and shapes. These bottles are more attractive and decent than reusable plastic bottles because of the eco-friendly features. Stainless steel bottles are free from toxins and BPA. Yes, there is no danger of BPA in these bottles. These water bottles don’t break, leach or sweat. You can wash stainless steel bottles in a dishwasher. You can use them in all types of weather conditions.

Pros of Stainless Steel Bottles:

  • Lightweight and decent.

  • No more toxins and BPA.

  • Dishwasher safe.

  • High-quality designs.

  • Highly durable.

  • Attractive designs and sizes.

Cons of Stainless Steel Bottles:

  • May get dent or scar on the external surface if dropped.

  • It may bring changes in taste and odor (Try using Coldest Water Bottle to avoid this issue).

  • May heat up when the temperature is higher (Focus on Coldest Water Bottle which has high quality insulated storage).

Reusable Aluminum Bottles:

You can find reusable aluminum bottles easily in the markets. These bottles have sleek designs and shapes. These are attractive but these have some negative points.

Reusable aluminum water bottles are reactive because of the aluminum surface. These bottles show high reactivity if touched by acid. This is why most aluminum bottles are lined with the epoxy layer. This layer ensures that there will be no reactivity if the bottle comes in contact with an acid. However, this epoxy lining may get damages with the passage of time.

On the other hand, some reusable aluminum bottles use plastic. This is not a healthy choice. Plastic contains BPA which is dangerous for health. However, reusable aluminum water bottles are durable but difficult to clean.


  • Trendy

  • Lightweight


  • High dent risk.

  • Possible BPA covers.

  • Cleaning is difficult.



Based on the above-mentioned details (also on pros and cons), I would prefer to choose reusable stainless steel bottles. Coldest Water Bottle presented by The Coldest Water is a highly recommended choice as it contains lots of prominent advantages. You should focus on these points whenever buying reusable water bottles for daily use.
