In an emergency or survival state of affairs, with the ability to entry protected water might imply the distinction between life and demise, as people can go about three weeks with out meals however solely three days with out water. Water is life, and also you by no means need to be caught with out it.
There are numerous moveable water filters and purifiers in the marketplace, so we reviewed the most effective backpacking water filters out of all of them that can assist you make the acquisition that’s best for you. Store good and keep hydrated — or else.
We cherished the Platypus GravityWorks once we reviewed it intimately earlier this yr. Whereas this high-volume filter is a prime performer, it’s overkill for solo use and supreme for teams of two or extra. For smaller teams, we suggest the 4L model, though Platypus additionally provides a 6L model for bigger teams. The Platypus GravityWorks is a light-weight system at 11.57 ounces (328 grams) and filters shortly, working by way of as much as 1.75 liters per minute relying on how a lot sediment is within the water. As soon as set with the soiled bag positioned above the clear bag, gravity does the work, with no laborious pumping required. The system is flexible sufficient in order that the clear bag can be utilized in a backpack as a hydration bladder or hung from a tree for camp use. It’s additionally compact and, when rolled up, takes up about the identical house as a Nalgene 1L bottle. The filter is replaceable (producer recommends after 1,500 liters of use). Most significantly, the hole fiber know-how filters out any particles bigger than 0.2 microns which removes 99.9999 % of micro organism and 99.9 % of protozoa. We’ve filtered some fairly turbid water with the GravityWorks through the years, and it has carried out each time.

Of all of the water filtration merchandise we examined, the Katadyn BeFree was one of many very lightest within the built-for-personal-use class. Weighing in at 2 ¼ ounces (64 grams), this private drink-through-the-filter system supplies on-the-fly hydration. One merely unscrews the reservoir bag from the filter lid, fills the reservoir with water from a spring or creek, re-attaches the filter lid, and squeezes away. The reservoir bag is delicate to the contact (versus Platypus reservoirs), and I used to be initially involved about breaking the bag by squeezing it, and different web evaluations we researched listed comparable sturdiness issues. These issues have been unfounded because it withstood our checks. This hole fiber filter removes micro organism and protozoa however not viruses. The filter itself is pretty sturdy and good for 1,000 liters of use. We examined the filter with the 1L bag, however Katadyn additionally makes 0.6 and 2L variants.

Finest Virus-Killing System
It’s vital to notice that the majority moveable water filtration programs don’t take away viruses. This can be particularly vital when touring outdoors of the US to locations with sketchy water provide programs. The World Well being Group estimates that almost 25 % of the world’s inhabitants is consuming fecally-contaminated water. Adenovirus, astrovirus, hepatitis A and E, rotavirus, norovirus and their ilk can flip a trip right into a catastrophe.
The excellent news is that there’s a technological answer accessible: UV gentle. The WAATR CrazyCap makes use of a LED UV gentle emitter constructed into the canteen’s cap to sterilize faucet water in a single minute, and water from springs and different wild sources in two and a half minutes. It’s also self-cleaning in that it activates each 4 hours for 20 seconds to maintain the bottle freed from mould, micro organism, viruses, and different dangerous pathogens.
It’s vital to notice that this system doesn’t filter water, so watch out to fill it with water that is freed from particles or different particulates. The UV-emitting cap is rechargeable in 4 hours or much less with a USB appropriate charger. A single cost lasts about one week. Security word: Don’t irradiate eyes.

Finest for Worldwide Journey
The Grayl Geopress stands out amongst water filters in that it removes not simply protozoa and micro organism, however viruses as properly, a rarity amongst filter programs. It additionally removes many heavy metals and chemical contaminants. That is particularly helpful in areas with polluted water sources. The system works like a French press — you merely put soiled water within the exterior container, insert the filter container, and plunge. It takes some effort and time to depress. The producer claims a 1L per eight-second movement charge, however the quickest I might totally deploy the plunger was 32 seconds, and this was with faucet water. I strongly suggest prefiltering water with numerous sediment/turbidity. Whereas the system is ruggedly constructed, it is without doubt one of the heavier and less-packable choices (doesn’t compress like delicate baggage). It should survive drops as much as 10 ft. The activated carbon-ion alternate know-how within the filter delivers great-tasting water. The filter additionally has a brief use lifetime of 65 gallons (250L). Additionally, you need to defend this filter from freezing.

Forms of backpacking water filters
The primary distinction between water purifiers and filters is the scale of the microorganisms they take away. Transportable water purification programs typically use boiling strategies, chemical substances like chlorine or iodine, or UV gentle to kill pathogenic organisms to incorporate protozoa, micro organism, and viruses. Most purification programs don’t filter out suspended solids within the water, so it can prove clear however sometimes “chunky.” Chemical drops are typically low-cost choices, however not the simplest in opposition to some significantly gnarly micro organism. Water filters work by passing soiled water by way of a filter media to pressure out protozoa and micro organism, however don’t typically take away viruses. Water from these programs is freed from sediment and solids however could include viruses, so it is advisable to watch out as to the place you supply your water. These choices are costlier than chemical drops since tools is required.
Virtually all the backpacking water filters reviewed right here meet or exceed EPA water filtration requirements. Most filter to 0.1 microns which eliminates most protozoa and micro organism (however not viruses). No matter system you select, we strongly suggest you learn this CDC Information to Consuming Water Therapy and Sanitation for Backcountry & Journey Use.
Boiling water
That is the most affordable and one of the crucial efficient backcountry water purification strategies. Merely fill a pot with water, set it to a rolling boil for not less than one minute (per the World Well being Group and Environmental Safety Company), after which pour the water by way of a clear bandanna or paper espresso filter right into a canteen. The professionals are that it’s low cost and is adequate to kill pathogenic micro organism, protozoa, and viruses. The cons are that it takes a range, gas, paper, or material filter medium, and plenty of time. It additionally sucks to drink sizzling water on heat days.
Chemical purifiers
Utilizing iodine or chlorine drops to kill waterborne pathogens is a reasonably low cost and easy course of. One merely provides the requisite dose of chemical air purifier to a canteen of water and waits a specified time period, typically half-hour to 4 hours. The professionals of this methodology is that it’s low-cost. The cons are many, because the water normally tastes like chlorine or iodine, is ceaselessly “chunky” since there isn’t any filtration system concerned, and also you would possibly nonetheless get the shits. Whereas chlorine has a low to average effectiveness in killing Giardia, it tends to have excessive effectiveness in killing micro organism and viruses. Neither iodine nor chlorine is efficient in killing Cryptosporidium. We suggest utilizing these strategies as a backup to fundamental backpacking water filter programs.
Ultraviolet gentle purifiers
A number of producers like WAATR and SteriPen make water purification programs that use ultraviolet gentle to destroy pathogens to incorporate viruses. Turbid water degrades their effectiveness as dangerous microorganisms can conceal from the sunshine behind particles within the water. Usually, these programs aren’t nice for processing giant quantities of water at one time. These programs require batteries or electrical charging, so they’re lower than supreme for lengthy journeys.
Pump filtration programs
These programs are old-school and most backpackers don’t use them anymore. One of many benefits is that they sometimes have siphon hoses which permits for simpler entry to very shallow water sources, and a uncommon few take away viruses. The cons are that pumping is a ache within the ass, they are typically costlier, they usually’re cumbersome, gradual, and heavy. They’re additionally onerous to scrub within the discipline. Because of this, we don’t suggest them for backpacking in most situations.
Hole fiber filtration programs
Most trendy backpacking water filtration programs use some type of a hole fiber filter tube encased in filter cartridges. These programs work by basically straining out particles bigger than just a few microns to incorporate most pathogenic protozoa and micro organism. Virtually all do not filter out viruses. A few of these programs depend on you to squeeze a bag containing the water to be filtered by way of the filter canister, and others are designed so you’ll be able to merely place or hold the soiled bag above the canister and permit gravity to do the give you the results you want. These filter cartridge programs virtually all the time require backflushing because the filters develop into clogged with silt, sediment, and different suspended solids. Some, just like the Katadyn BeFree, are all-in-one items combining the filter and the reservoir. Others are separate items just like the Platypus GravityWorks system.
Key options of backpacking water filters

A lot of the filtration programs listed right here will produce a number of liters of water in just some minutes. If it’s simply you, go along with the Sawyer Squeeze or Katadyn BeFree. If it’s you plus others, go for the Platypus GravityWorks or the 2L variant of the BeFree.
Pace
Pace of filtration is a priority once you’re on the go. Each break taken to filter water on the path equates to distance not walked. I desire the Platypus system, so I are likely to plan breaks round water sources so I can relaxation my physique whereas filtering water. For on-demand, on-the-fly filtration, go along with the Sawyer Squeeze or Katadyn BeFree. Attempt to be environment friendly within the backcountry. Wasted vitality equals extra fatigue. Search for programs that don’t take a very long time to supply clear water.
Advantages of backpacking water filters
Well being and hydration
When within the backcountry, it’s crucial to attenuate danger as you might be normally hours if not days from assist. Dehydration and heat-related sicknesses can result in disastrous penalties if not anticipated or shortly addressed. The human physique can survive for weeks with out meals, however solely days with out water, and staying hydrated with clear, protected water is vital in sustaining peak efficiency.
Packability
Like weight, packability is a significant consideration when deciding on backpacking tools like water filtration programs. I desire to take the least quantity of substances that gives me the best quantity of utility and security margin. When every thing takes up cubic inches in a backpack, I lean within the path of small, collapsible, and stackable. When deciding between two equally performing programs, select the smaller and lighter one. All the filtration programs we reviewed are light-weight and simply stowed in a backpack — and a few are smaller, a lot smaller than others.
Ease of use
Even a Marine might function essentially the most difficult system we reviewed. Ease of use is vital. When touring removed from house in areas with restricted assets, simplicity reigns. Sometimes, the less the variety of course of steps or shifting components, the easier the system. The perfect-designed water filtration tools is that which you’ll function when fatigued, at midnight, or in an emergency the place time is of the essence. Identical to your drill teacher advised ya, Okay.I.S.S.: Preserve it easy, silly!
