Purchaser’s Information: The 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, however it’s useful to know the distinction when selecting.

Filters vs. Purifiers

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

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

Filter Time and Circulate Price

Our picks for greatest water filters differ broadly by way of how shortly they will filter water, starting from 30 seconds to half-hour to 4 hours (chemical remedies). Forms of filters and strategies of purifying will play a component, in addition to movement charge.

Circulate charge is a unit that measures how shortly a specific amount of water could be filtered. Circulate charges for gravity, pump, or squeeze filters listed right here differ anyplace from 1-3 L per minute. In case you are encountering a gradual movement charge along with your filter, it could 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 it’s essential 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’ll be touring by means of 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 unique model of filter could be greatest.

And if you’ll 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 vital 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 common 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 may well filter as much as 3L of water at a time).

Filter methods 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, provided that I all the time carry a 1L bottle anyway.

Sturdiness and Longevity

The lifespan of a filter vastly is determined by its filter methodology (cartridge, hole membrane, chemical, or UV mild). 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 it’s essential to change the cartridge. Alternatively, with different filters that last more, chances are you’ll want to exchange your entire unit on the finish of its life. The LifeStraw is an instance of this; it may well filter round 4,000L, after which it’s going to cease working and must be changed.

For UV strategies just like the CrazyCap filter bottle and SteriPENs, they’ll final endlessly so long as you cost or proceed to exchange the batteries (barring any injury, in fact).


Lastly, there’s the worth. We suggest making an inventory of your high two or three decisions after which weighing the professionals and cons. Any filter might be an funding.
