We picked the Universal Filter in our 2019 Summer Buyer’s Guide as one of the best pieces of travel tech gear. The filter has a two-stage process with a microbiological filter and an activated carbon capsule so it protects against bacteria, parasites, microplastics, and chemicals.
Removing 99.99 percent of bacteria and protozoa, the Meta Bottle is a collapsible and BPA-free. Fill it with water, then shake for speedy filtration—up to two liters per minute. Plus, it’s dishwasher safe.
Collect stream water in one of Sawyer’s 32-ounce pouches, then filter it through the hollow-fiber membrane to remove bacteria and protozoa. The pouches are collapsible (each weighs only three ounces) and reusable, and you can drink straight from the filter’s nozzle or pour the water into a bottle for later.
Katadyn took a handy one-liter water bottle, which rolls up small to save space in your pack, and put a 0.1-micron microfilter in its nozzle that removes 99.9 percent of nasties. The BeFree can purify up to 1,000 liters over its lifetime.
Instead of filtering water, these dissolving tablets purify it with EPA-approved sodium dichloroisocyanurate. Complicated name, but essentially it kills viruses, bacteria, and cysts in a quart of water in 30 minutes. The price ($10 for 30 individually wrapped tablets) and tiny size make Aquatabs the ideal backup on long trips.
Boyan Slat, the 24-year-old founder and CEO of the Ocean Cleanup, has finally launched a system he says will rid the Great Pacific Garbage Patch of half its plastic trash in five years.

Is it safe to use one of those Brita pitchers to filter river and lake water while camping? -Eric Oakland, CA
I'm building an emergency kit into a small fanny pack for day hikes in Colorado. I don't have space for cookware so I was wondering if there's a titanium water bottle that could be used to boil water over a campfire if necessary. Jerry Colorado Springs, CO
Hi, I want to purchase a water filter or water purifier to turn my day hikes into some overnight trips. I have been doing a lot of research but can't seem to figure out which one I need. I'll primarily be hiking in the Northeast and only in North erica, so is there a need for an actual water "purifier"? Thanks in advance. Kane Red Bank, NJ
Im going backpacking in South Dakotas Badlands, and everything I read says that you have to bring in your own water. For a four day trip, that could mean as much as five gallons. What type of water containers should I use to most effectively carry this much water? Junior Minneapolis, Minnesota
I know that you need to filter (or treat) water before drinking it, but what about the water I use to rinse my hands or clean my cookpot? How resilient are those nasty little giardia and cryptosporidia parasites? Do they die and go away when the water that carries them evaporates? Will an alcohol-based sanitizer kill the remains of them on my hands, or do I need to filter the water first? Bruce Cortland, New York
