Why Should You Use Reusable Filtered Water Bottles?

If you are a travel buff, a portable water bottle with a filter should be your best and most important companion. Many travelers prefer to buy packaged drinking water bottles when traveling abroad or in an area where the water is not safe.

As a responsible budget traveler, I never promote buying packaged drinking water. I know it is safe and good practice to be safe while traveling in an unknown country. But why not using a water filter for travel?

A portable travel water filter not only eliminates the chance of getting sick while traveling but also helps to reduce and eliminate single-use plastics that are polluting our environment.

And most importantly, a travel water filter saves a lot of money. I’m a budget traveler and I know the value of every single penny. If you spend $2 a day on bottled water, it can cost you more than $700 on a year-long trip.

All of these filtered water bottles and travel water purifiers are under $100. You may also like to read another article on how do I save money on food while traveling.

Is A Portable Water Filter Worth It For Travel?

Travel water filters are not too expensive. As mentioned earlier, you can easily find some of the best water filters for travel under $100 on Amazon. This is also considered one of the most important camping essentials.

A portable travel water bottle with a filter can save money, the environment, and your body. With a travel water purifier bottle, you can carry less water and fill up as you go. This is a great help for your shoulders while going for a long hike or long day travel across the globe.

So yes, a small investment on a travel water filter or a water purifier bottle is completely worth it.

Buying Guide for a Travel Water Filter Bottle

Assuming that you are convinced to buy a portable water filter for travel. With a rise in international travel, you will get to see the abundance of water filters and water purifiers in the market. Don’t be puzzled while choosing the best portable water purifier for travel. Here are some important things to consider when buying a water filter or purifier.

Filtration Technology:

Carbon filters are the best for removing heavy metals and bacterial contaminants. The Straw filter is also a common type of filter where you suck on the mouthpiece and the water is filtered through the straw on its way up.

While a straw filter gives you instant access to filtered water, a Gravity filter usually works slowly but allows you to filter a large amount of water. A Pump filter is a simple and easy process. Once you pump the water through the filter you can drink it for up to 48 hours. 

Pore Size:

The pore size of the water filter indicates the smallest particle that can pass through the filter. Experts recommend buying a water filter for travel that has at least a 0.1-micron filter to remove microorganisms, microplastics, and silt.

Bottle Construction:

Metal bottles are increasing in popularity for their durability and effectiveness, but they are a little bit heavy and pricy. If you buy a plastic water purifier bottle for travel, don’t forget to check if it is BPA-free, else it may cause some serious decease.

Water Filter or Purifier:

Water filters are very effective to remove protozoan cysts and bacteria, not viruses. Viruses are too small that can be eliminated by a water purifier. If you are traveling to a developing country, you can consider buying a water purifier.
