Backpacking Water Filters

The Best Backpacking Water Filters are those that you can easily carry around in a backpack, and are generally flexible and fold up when not in use (so they don’t take up much space.) These are usually BPA free pouches that you place the unpurified water in (from any source) and then let it pass through the filters down into a collector source.


They rely on using gravity instead of a mechanical device to slowly turn contaminated water into clean, safe drinking water, through trickle down water purification. The Katadyn Pouch Filter and the Platypus are two good examples of backpacking water filters.

Katadyn Water Filter

Katadyn is my go-to water filter for survival or emergency outdoor usage. The Katadyn Pocket Water Filter is a manual pump type of water filter than has a very high level of water purification capabilities. I would choose this one over all the others because it is manual and durable, and make it my primary survival filter. 

It is also the Best-selling emergency preparedness water filter with the highest ratings.

Super High Quality construction, it is made to last for the longhaul.  The filter’s silver infused ceramic element is effective against bacteria and protozoa, using a Micro Filtration method. Up to 1 quart (1 liter)/minute Cartridge Capacity, up to 13,000 gallons (50,000 liters), depending on water quality. This pocket water filter is a favorite of outdoor enthusiasts, international travelers, and the U.S. Military.

Platypus GravityWorks Water Filter

Platypus Gravity Works Water Filter uses two pouches. One has the contaminated water you want to filter. The second is the collection pouch where the purified water flows into. It filters about 4 liters in 2.5 minutes. It only weighs about 10 ounces too, so it won’t put a lot of weight or volume into your backpack or day bag. It filters out the harmful things like Giardia, Bacteria, Protozoa, Cryptosporidium, E. coli, Salmonella and Cholera.

Survival Straws

Survival Straws are very simple and compact filters that you can use out in nature when you need water and don’t have a more powerful filter handy. The LifeStraw is the most popular pen sized water filter, where you just suck the contaminated water through the filter, like a straw action, and get clean, safe drinking water directly into your mouth.


These are the smallest filters, and filters of last resort. I would definitely have a few of these on hand in your pocket for emergencies, but will rely primarily on my Katadyn or Platypus for more complete water purification. For more information, you can also see Survival Water Filters.
