Water Filtration Is Crucial for Proper Hydration

Unfortunately, water has its limits… it can’t always stay fresh and clean.

For those who frequently travel, work out, or spend time outdoors, you know how essential a proper filtered water bottle is. When you’re out in the wilderness or in certain areas of the world, the water that’s available to you can often make you ill.

Of course, there are many options for purifying water. For example, boiling the water prior to use. But this is time-consuming and requires materials that aren’t always available. You can also stock up on bottled water, but this is big no-no from an environmental standpoint.

So, the best method for making sure you have access to clean drinking water when you’re on the go is a filtered water bottle.

How to Purify Water

There are several methods used to filter water:

  • Activated Carbon – You’ll often see activated carbon listed as a water filtration method. Carbon is a great choice for filtering heavy metals, chemicals, and enhancing the flavor of water. This is also referred to as the absorption method.
  • Ion Exchange – Ion exchange is used as a method to soften hard water. The process is reversible and the packs containing ion exchange resins can be washed through with excess ions.
  • Reverse Osmosis – The process of reverse osmosis is cost effective and useful for removing unwanted molecules and impurities within water via filtration through a semipermeable membrane.
  • Ultraviolet Light – UV light can be used in water filtration to remove impurities and kill microorganisms.

The usefulness of these methods depends on how often the filters are used and what kind of water you’re filtering. If you need something on the go and have some time to kill, UV light is a solid choice. However, if you need quick water filtration, activated carbon is the way to go.

Water Bottle Materials

Reusable water bottles come in a plethora of shapes and sizes. You can also find them in intricate designs and colors. When it comes to the materials used to create water bottles, you’ll find there are three main options.

  • Plastic – Plastic water bottles are a major source of pollution. From the process to create the bottles, to the end result of an extremely slow decomposition, plastic bottles are a bane to our environment. However, reusable plastic bottles are a step in the right direction.
  • Metal – Metals are an even better choice for reusable water bottles. They’re more durable, resulting in a longer lifespan than their plastic counterparts. Stainless steel might be heavier than plastic, but it will last longer.
  • Glass – Aesthetically pleasing? Yes. By all accounts glass water bottles are beautiful specimens. Glass bottles are recyclable and are made from natural materials, so they’re environmentally friendly. Unfortunately, there are safety concerns for glass water bottles. They can break and become a hazard. Luckily, there are plenty on the market which feature a plastic outer shell to protect the bottle from damage.

Final Thoughts

Having access to potable drinking water should never be a hassle. Whether you’re traveling, hitting the gym, or preparing for a disaster, you need to be able to stay hydrated without the risk of illness.

Hopefully this list points you in the right direction to help you choose one of the many filtered water bottles available.
