Choosing the right safe, BPA-free water bottle for you

We all know how important it is to stay hydrated, and due to concerns about the health, safety, cost, societal and environmental impact of bottled water, many people are switching to portable, reusable water bottles.

There have been reports of bottles leaching toxic chemicals such as Bisphenol-A (BPA) into the water, which makes it hard to decide what type of water bottle to buy.

This guide will help you select the right water bottle to keep you and your family safe, healthy, and well-hydrated, and includes some tips for improving the taste of your tap water.


  • Capacity

The capacity of the bottle determines how much water you can carry. And so depending on the activity, you are involved in and your preferences, you can choose from 500ml all the way to 2 liters.

  • Material

Water bottles are either made from stainless steel and aluminum or plastic. The former is best if you are involved in vigorous sports that require sturdiness of the bottle for durability and thermal properties. The plastic ones are for light sports. Look for a material that is BPA free as it is a health concern.

  • Shape

The shape of the bottle is important as it should fit precisely on any standard bottle cage for both cyclists and motorists. Running bottles should be slim and ergonomic for better holding.

  • Insulation

An insulated bottle is double walled with a vacuum or foam middle layer to help keep the water cold and hot accordingly for a longer time. As such they are ideal when the weather is cold, and you need to keep your drink hot and vice versa.

  • Transparency

If you only need a water bottle to hold drinking water, then transparency is not an issue. However, in the event you may regularly want to mix sports powders, then you should go for the transparent one as it allows a clear vision of the content.

  • Mouth Gape

Mouth Gape

Narrow gapes are great when drinking water while the wide ones make it easy to add ice cubes to the water as well as clean. And so go for one that meets your needs.

Stainless Steel Water Bottles

Stainless Steel Water BottlesStainless steel water bottles have become very popular in light of the recent concerns about the safety of plastic bottles.

Stainless steel bottles are of medium weight, and when properly constructed, will not leach harmful chemicals into the water.

They are quite durable, but thin ones may dent if hit hard enough.

Stainless steel bottles should not be used for hot beverages, or acidic liquids such as orange juice or Gatorade.

Lined Aluminum Water Bottles

Lined Aluminum Water BottlesLined aluminum bottles are a nice alternative to stainless steel bottles. They are lighter weight and safer to use with acidic beverages, but may dent more easily.

Lined aluminum bottles have a thin resin layer on the inside to separate the water from the aluminum.

Aluminum has been linked to causing Alzheimer’s disease, so you should never buy an unlined aluminum bottle. In addition, it is important to pick a bottle manufacturer that uses a safe lining.

Glass Water Bottles

Glass Water BottlesGlass is the top choice for keeping your water safe and tasting great.

Glass is non-reactive, so it will not leach chemicals into your water (or any other beverage, including acidic liquids like orange juice).

However, it is the least durable of all materials, since dropping a bottle will almost surely break it.

It can work well for a bottle that stays in the office or your car, but in other situations, you may find yourself with a shattered bottle and a fine mess to clean up.

Plastic Water Bottles

Plastic water bottles have been a hot topic ever since the news broke that many plastic bottles, including the original polycarbonate Nalgene bottles, were leeching the potentially harmful chemical Bisphenol A (BPA) into water.

Luckily, there are some safe plastic bottles that will not release toxins into your water if used properly.

Look on the bottom of the bottle for its plastic recycling symbol, #2 (high density polyethylene), #4 (low density polyethylene), and #5 (polypropylene) are the safest. #1 (polyethylene terephthalate), #3 (polyvinyl chloride), #6 (polystyrene), and #7 (other, including polycarbonate), bottles should be avoided, as these may leach harmful chemicals into your water.

 bottom of the bottle for its plastic recycling symbol

Even if you have picked a #2, #4, or #5 plastic bottle, heat and light exposure may cause a plastic water bottle to leach chemicals into your water.

Plastic water bottles should not be left in a hot car parked in the sun, nor should water be left in the bottle for too long.

If your water ever smells or tastes like plastic, don’t drink it! Plastic water bottles are great for the gym, since you can fill it up when you get there, and many have convenient pop-up tops or straws so that you can grab a quick drink while you are working out.

Plastic gets top marks in terms of durability, as it is quite difficult to break most plastic bottles. Models with convenient tops also score high in practicality.

Plastic bottles are often the least expensive option, and bottles are safe as long as the right plastics are chosen.

There are some great BPA-free Camelbak bottles with a nice straw-top design, or a traditional lid, both of which have a wide enough mouth for ice.

Filtered Water Bottles

Filtered Water BottlesA filtered water bottle has a filter built in to purify your water as it passes through the bottle.

These bottles are typically made of plastic, so the same precautions taken with plastic bottles must also be taken with filter bottles.

Filter bottles are considerably more expensive than regular plastic water bottles, however, they will ensure that you are drinking high-quality, safe water. These are an excellent choice if you are not sure about the quality of your water source.

There are many different types of filters in these bottles; some filter chemicals, others filter micro-organisms (bacteria/viruses), and some do both. Filtering may also make your water taste better.

Tips for improving the taste and purity of your drinking water

Tips for improving the taste and purity of your drinking water

#1 Let your water sit in a decanter

Bad taste in water can often be attributed to gases dissolved in the water.

Chlorine is a very common example of a gas that is added to water during purification to help kill any bacteria or microbes present in it.

However, if you’ve ever gotten a mouth full of pool water, you know that chlorine is not tasty!

If you leave your water in an open pitcher or decanter in the fridge overnight, these gases will come out of the solution in the water.

You’ll be amazed at how much difference in taste this can make. However, still water shouldn’t be left out too long or it may start to grow bacteria.

#2 Let your water get cold!

This one may seem obvious.

However, blind taste tests between bottled water and tap have proven that very often. People associate bottled water with a better taste simply because they usually drink bottled water when it is colder. So throw a pitcher or your reusable water bottle in the fridge, and have it cold!
