What to Look For In a Water Purifier?

Portable water filters for travel are lifesavers, especially if you’re traveling to countries with poor water quality.

With a rise in international travel, the availability of water purifiers in the market has also increased. Therefore, it can often be a bit tough to choose the best portable water purifier.

But, worry not. I’m here to help. Here are some things to consider when buying a water purifier.

Filtration Technology

First off, you must check the filtration technology used by a travel water purifier.

Most models have carbon filters, as they’re the best for removing heavy metals and bacterial contaminants. Additionally, activated carbon helps improve the taste and smell of water.

Another technology that you’ll find in travel water purifiers is electro-adsorption. In this method, the impurities are separated from the water, based on charge.

Some purifiers have dual technologies. As a result, they’re often more expensive but have better performance.

Pore Size

The pore size indicates the smallest particle that can pass through the filter.

Thus, if a filter has a pore size of 0.1 microns, only particles smaller than that can pass through it. The filter will trap every organism or substance larger than 0.1 microns.

A travel water purifier must at least have a 0.1-micron filter. Experts regard this size as effective in removing microorganisms, microplastics, and silt.

Types of Water Purifiers

Typically, there are three types of travel water purifiers:

  • Gravity bags
  • Filtration pumps
  • Water bottles

You can choose the right type depending on your preference and the amount of space in your luggage.

Water pumps usually take up more room than the other two types. Some water bottles can be contracted to fit in the luggage. Meanwhile, others are already compact enough to fit most backpacks’ side pockets.

Possibly the easiest purifiers to carry are the gravity bags since they fit in tight spaces too.

Here is a depiction of all the various types of water filers and purifiers.

Types of Water Filters


Are you traveling alone, or is it a family trip? Depending on the number of people in the group, you should buy the travel water purifier accordingly.

Travel bottles normally have a capacity of 16 to 32 ounces.

Final Words

Regardless of how often you travel, you should have a travel water purifier at home. It’s a necessity for every time you’re out in an unknown place.

Alternatively, water purifiers make a wonderful travel gift for a friend or family member who loves to be on the go.

In this guide, we’ve discussed the best travel purifiers, including gravity bags, bottles, and filtration systems.

Thus, you’ll find a suitable option to ensure safe water consumption irrespective of where you are in the world.
