Are you ready to throw away single-use plastic bottles? Here are the top environmentally friendly alternatives...

Reusable water bottles have become mainstream, thanks in large part to David Attenborough's attention to the shocking plastic pollution problem.

Approximately 20,000 single-use plastic bottles are produced every second in the world, but none of them can be completely decomposed. Environmentalists predict that by 2050, there will be more plastic than fish in our oceans. Very depressed, right?

Fortunately, there are now a variety of beautiful and practical reusable water bottles that can keep you hydrated and environmentally friendly.

The doctor recommends drinking at least six to eight glasses of water a day. Using a bottle is a great way to keep track of how much you drink-try to take a note every time you fill it up.

Our best water bottle choices for 2020 are:

All water bottle materials (except BPA, which is related to health risks) should not cause any harm.

Glass is made of natural materials, so there is no risk of dirt seeping into your beverage when heated or cooled, and most reusable plastic bottles are now BPA-free. Make sure to hand wash reusable plastic bottles because the combination of heat and detergent will promote leaching. This also means that there is no microwave.

Most metal bottles are made of stainless steel or aluminum, and many cookware are made of stainless steel or aluminum and are considered safe.

Glass bottles, stainless steel bottles and plastic bottles have their own advantages and disadvantages, depending on personal preference. Is the durability of outdoor travel your top priority? Or do you want a lightweight option to grab during a gym workout?

Let's take a quick look at the options.

Advantages:-There is no risk of glass contaminating the smell-it is easy to see how much is left in the bottle

Disadvantages:-It is easy to break if dropped-Cannot keep the drink cool for a long time-Not suitable for hot drinks

Advantages:-The best thermal insulation to date-In our one-hour cold test, the temperature usually rises only 0.4C, compared with 5.4C for plastic and 7.3C for glass-Can withstand and insulate hot drinks-Durable

Disadvantages:-may be heavy and bulky-may give your water a metallic taste

Advantages:-The lightest option-many have a mouthpiece for easy drinking on the go

Disadvantages:-Very easy to scratch and crack-Cannot keep the drink cool for a long time-Hot drinks will melt it-May give your water a plastic taste

Wash the bottle by hand with hot water and detergent after each use to prevent the growth of bacteria. If it smells bad, add a teaspoon of sodium bicarbonate.

After washing the bottle, put it upside down to air dry and remove the cap to prevent moisture retention. Store without a cover for thorough ventilation.

To find the best reusable water bottles on the market, the Good Housekeeping team tried 28 water bottles made of glass, stainless steel and plastic.

We rigorously test the requirements of each bottle, from insulation and leakproofness to ease of use during exercise. We noticed how comfortable each bottle is to drink, how easy it is to clean, and whether it has any smart design features, such as a rubber base for grip.

The sturdy bottle is very comfortable to drink, and there is no leakage at all. There are three sizes to choose from and more than 100 colors to choose from, including some eye-catching patterns.
