Purchaser’s Information: The right way to Select a Water Filter

The LifeStraw Peak Series squeeze filter next to an alpine stream

Water filters and water purifiers work in comparable methods, nevertheless it’s useful to know the distinction when selecting.

Filters vs. Purifiers

Filters defend in opposition to protozoa or parasites (resembling cryptosporidium and giardia) in addition to micro organism (like E. coli or salmonella), microplastics, dust, and particles. Micro organism is the primary concern whenever you’re consuming out of unsafe water sources within the backcountry or distant areas.

Purifiers go an additional step by defending in opposition to and filtering out viruses. That is extra of a priority whenever you’re touring internationally or to rural locations the place clear water will not be accessible.

Filter Time and Stream Price

Our picks for greatest water filters range broadly by way of how rapidly they’ll filter water, starting from 30 seconds to half-hour to 4 hours (chemical therapies). Kinds of filters and strategies of purifying will play an element, in addition to circulate price.

Stream price is a unit that measures how rapidly a certain quantity of water will be filtered. Stream charges for gravity, pump, or squeeze filters listed right here range anyplace from 1-3 L per minute. If you’re encountering a sluggish circulate price along with your filter, it might require priming or backflushing.

Much like needing to prime a range, some water filters require priming earlier than preliminary use. Examine the directions (it varies by filter) on how to do that. Backflushing is a course of the place you have to clear water out of the filter system after use. This primarily applies to filters with pumps, tubes, or tubing, and it ensures the within of the filter stays dry and clear.

One other consideration right here is location: if you will be touring by a desert panorama, there could also be few to no timber (a necessity to hold some gravity filters correctly). For that sort of setting, a distinct model of filter could be greatest.

And if you will be touring with a companion or group, the non-public LifeStraw filter clearly received’t be the best choice (though we adore it as a backup!).

Packed Measurement

This is a crucial level for ultralight and light-weight backpackers. You’ll wish to select a filter that works greatest for you and the way a lot water you’ll want, however one that may additionally slot in your pack.

Filters just like the Sawyer Squeeze and Katadyn BeFree are standard as a result of the precise filter unit is so small, and the load is near nothing. The Sawyer Squeeze weighs simply a few ounces, whereas the Katadyn weighs 6.8 ounces (however bear in mind, it could actually filter as much as 3L of water at a time).

Filter techniques which have water reservoirs and tubing additionally roll and pack down pretty small. My private choice on group journeys is a gravity filter system, whereas on solo journeys — although they weigh barely extra — my choice is a water bottle filter/air purifier, on condition that I all the time carry a 1L bottle anyway.

Sturdiness and Longevity

The lifespan of a filter drastically is dependent upon its filter technique (cartridge, hole membrane, chemical, or UV gentle). Backpacking water filters can final anyplace from 250-4,000L.

Ones that use a cartridge are likely to final anyplace from 200-500L earlier than you have to change the cartridge. Then again, with different filters that last more, chances are you’ll want to switch the whole unit on the finish of its life. The LifeStraw is an instance of this; it could actually filter round 4,000L, after which it should cease working and should be changed.

For UV strategies just like the CrazyCap filter bottle and SteriPENs, they’ll final without end so long as you cost or proceed to switch the batteries (barring any harm, after all).


Lastly, there’s the value. We suggest making a listing of your prime two or three decisions after which weighing the professionals and cons. Any filter can be an funding.
