What to Look for in a Backpacking Water Filter
Micron Rating
A smaller micron rating means finer filtration. Look for filters with at least 0.02 microns, which remove bacteria and protozoa. For serious travel, a 0.01 µm filter can remove smaller particles, including most bacteria, protozoa, and some viruses.
What It Filters Out
Not all filters are equal. Some focus on chlorine and taste, while others remove parasites, heavy metals, and microplastics. Choose based on your environment.
Durability and Longevity
If you’re travelling long-term, invest in a sturdy filter with replaceable cartridges. Cheaper filters may save money upfront but wear out quickly.
Ease of Use
Filters should be simple to operate on the go. Bottles are easiest for daily travel, while pumps and gravity bags are better for groups or extended outdoor trips.
Cleaning and Maintenance
Keeping your filter clean ensures it lasts. Learn how to backflush or replace cartridges, and always dry your filter before storage.
