The importance of proper hydration
Staying hydrated, particularly with water, has been proven to have a multitude of benefits. Drinking water is crucial for helping your body to regulate internal temperature, keeping your joints lubricated, keeping your organs working properly, and delivering nutrients to different cells in the body.
Hydration also improves your mood, cognition and sleep quality.
The fact is, although water is so important for day to day living, you may not always have direct access to purified drinking water. Whether you ran out of water on your hike or camping trip, or the water at the river close by is inviting you for a cool drink, you want to ensure your water is fit for drinking.
One revolutionary way to access purified water on the go or in dire situations is with a water filter straw.
What is a water filter straw?
A water filter straw is really as it sounds. They are portable, lightweight, and easy to use. You simply stick the straw into the water source and drink. The straw filters out impurities, parasites and bacteria to deliver clean, purified drinking water.
These straws are affixed with a micron number, which is the average size of the openings in a straw filter. The smallest is a 0.1-micron opening. This number also informs you of the level of filtration the straw is able to provide.
So, if the micron number is 0.1 anything bigger than that will not be able to pass through the straw. The other more popular sizes are 0.2 to 2 microns. In essence, the smaller the micron rating, the higher the filtration.
