Types of Water Purifiers for Travel

There are various types of travel water purifiers with different levels of purification. Some common types include:

• UV-C pens: These portable water purifiers use ultraviolet light to neutralize bacteria, viruses, and protozoa.
• Gravity filters: These filters push water through a filter cartridge, which physically removes pathogens and other impurities.
• Pump filters: This type uses hand-operated pumps to push water through the filtration system.
• Bottle filters: These are similar to a typical water bottle but contain built-in filters within the water bottle, allowing for easy drinking and purification.

You can choose the right type depending on your preference and your luggage’s space. Water pumps usually take up more room than the other two types. Some filtered water bottles are collapsible to fit in your travel bag if you need to optimize your space for a long-haul trip.

Meanwhile, others are already compact enough to fit most backpacks’ side pockets. Gravity bags are the most portable water purifiers since they can filter water in tight spaces while offering more capacity.

What to Look For in a Portable Water Purifier for Travel

Portable water filters for travel are lifesavers, especially in countries with poor water quality. With a rise in international travel, the availability of portable water purifiers in the market has also increased. Therefore, choosing the best portable water purifier can often be challenging, so here are some things to consider when buying a water purifier to find the one that fits your needs the most.

Filtration Technology

First, you must check the filtration technology a travel water purifier uses. Most models have carbon filters, which best remove 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. This method separates the impurities from the water based on charge. Some water purification systems 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 water filtration system. Only smaller particles can pass through a filter with a pore size of 0.1 microns. 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.

Capacity

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 usually have a capacity of 16 to 32 ounces.

Filter Life

When investing in a water purifier, it’s crucial to consider its filter life. Water purifiers should have a long-lasting filter and clearly state the number of gallons or liters they can purify before needing replacement.

Effectiveness

The most important feature of a water purifier is its effectiveness in removing harmful contaminants. Look for a portable water purifier that can eliminate at least 99.9999% of bacteria, 99.99% of viruses, and 99.9% of protozoa. Also, opt for a water purifier certified by reputable agencies or organizations, such as the Environmental Protection Agency (EPA) or NSF International.

Weight and Portability

Since this will be traveling with you, select a portable water purifier that is lightweight and easy to pack. Compact designs, fast purifying times, and little to no setup are essential for seamless integration into your travel gear.

Ease of Use

Finally, consider the ease of use of the water purifier. Some water purification systems may require pumping, chemicals, or waiting for gravity to work. Gauge your comfort level with operation and maintenance and factor that into your decision.
