A Quick Buyers Guide To Reusable Water Bottles
It sometimes is hard for you to decide the best option for yourself. Especially when there are so many options to try and they all seem promising. That is why we researched and tested various products on our own; to further narrow it down to just six best bottles.
While we worked really hard testing and shorting them out on the best-known parameters like; durability, price, leak-proof, insulation, ease of use, cleaning, size, types of cap or straw and most important how long it can keep the drink still ice cold. I regret you still have to make the final call picking the one that best suits your needs.
Before you hit the market or reach to amazon store; we recommend you to ask yourself a few basic questions:
What bottle type is best for you?
The best bottle type is the one which best serves your need. So the first thing you should ask yourself is for what are you going to use this water bottle.
Suppose, you are backpacking for a camping trip with friends in the summer. Now you do not just need a bottle that can keep things cool; but also should have large storage.
Similarly, for gym and sports, you need one that is more rugged and come with a straw for convenience. Thus knowing your plan for using your water bottle; quickly narrow down your choices.
You simply do not want to take an Iron flask with 64oz capacity for your yoga classes.
You need something slick and good looking that match well with your yoga mats. Some bottles like the hydro flask water bottles are well suited for a wide variety of activities.
While there are some like The Coldest Water Bottle are good for everyday activities and sports. So identify your needs and choose wisely.
What material do you want?
Plastic bottles are really cheap and they do come with appropriate markings. These came in really handy for those who always have drinking just the right amount on their minds. But there is downsides to it; plastics are not a good poor conductor of heat and thus don’t fit for keeping cold or hot drinks for long.
Moreover when in contact with hot drinks for long they start to break down thus releasing BPA.
It is a chemical well known for negatively affecting the reproductive system and be detrimental to child development. See this article from the National Toxicity program for more information regarding the effects of BPA.
On another hand, while insulated metal bottles are good for health, keeps your drinks colder for longer and are fashionable.
They do have this issue of weight and require regular cleaning; against the plastic bottles which do not need any.
So do go with the insulated metal bottle but while knowing they are not always cheap and may impart that metallic taste.
What do you want? – Quick access vs screwcap
Most brands provide both quick as well as screw cap options for their customers; while some offer just one or another. Ideally speaking they both are quite useful; as having a screw cap adds up to the insulation capabilities while having quick access ensures one-hand operation.
In regular day to day operations having an easy to access solution either in the form of straw or one push cap operation is quite advantageous.
It not just a convenient option than a screw cap; but also encourage one to drink more water. It has been found that by using a straw you can increase your daily water consumption by 5 to 10%.
Similarly, when planning an outside trip it’s better to use a screw cap. Using it not just makes it hold inside temperature for longer; but also makes your bottle spill-proof and leak-proof.
As there is always a chance of water spilling or get leak off the sides of the straw. The best part is they require less cleaning and are easier to clean.
What’s your preferred drink type?
It’s important to ask what’s your preferred drink type? As it largely affects your choice in terms of brand and insulation type. There are some brands and insulation material that works well for hot drinks but not that good when it comes to cold drinks or chilled water.
Similarly, others work better when it comes to cold drinks or water; while some works mildly similar for both hot and cold drinks. For example, Iron flask water bottles work far better when it comes to cold drinks but not too good when it comes to hot drinks or water.
Similarly, embrava holds hot water or drinks hot for longer than a cold drink by two hours.
So it’s important for you to know how well will this bottle works when used for hot drinks or water. In-state of doubt just go with brands like the camelback eddy; which are well known to perform better for both hot and cold drinks.
Narrow vs wide mouth
When using a water bottle it is easier to drink from a narrower mouth than a wide one. Moreover, the wider it gets the harder it is for you to drink without splashing it all over your chest.
This means it is wiser to have a narrower mouth; especially when you have to drink while you walk.
On another side having a wider mouth has its own advantages. It makes it easy to clean or fill in some water. The best part is you can fill it with large ice cubes; which you simply cannot with narrower mouth bottles.
The other advantage of wider mouth is its versatility; it easily fits with a number of different filters and accessories.
