  • When buying a water filter, look at the micron size. This is a measure of how efficient the filter is. Filters with the smallest micron sizes are the most efficient at filtering impurities in water.
  • Also, examine a filter’s weight and size. Although most portable filters are small, some are very heavy, depending on the material used to make them. Ensure you purchase the most convenient size, especially if you are an outdoor enthusiast.
  • Other factors to consider include the cost of the gadget, ease of use, efficiency in filtering different pathogens, and the speed of filtration.


Q: How do portable water filters work?

A: Portable water filters have a replaceable cartridge that contains layers of permeable material. Water is made to pass through this filter, and contaminants such as mercury, lead, iron, dust, protozoa, and most bacteria are filtered out.

Q: How should I maintain a portable water filter?

A: Some maintenance practices include washing your portable water filter with hot water to kill bacteria every time you use it. During the winter, keep your kit at body temperature to ensure it does not freeze and become ineffective. Also, remember to replace the cartridge when necessary. 

Q: How can I tell if my water filter needs replacing?

A: First, check its lifespan rating. If you have achieved the gallons it is rated to filter, then it's time to replace it. Also, be aware if the flow rate drops significantly. The filter gets clogged with particles, and if the speed of filtering drops, you have to replace it.

Final Thoughts

On the other hand, if you need an economical unit that will still keep impurities out of your drinking water, we recommend the Sawyer Products MINI Water Filtration System.
