What to Look for in a Travel Water Filter or Purifier

Before we undergo a few of our really useful water filters, we needed to cowl what you need to be in search of in a water filtration machine.


What can a Water Filter Remove?

Probably crucial query you must ask when looking for a water filter or air purifier is what it’s able to eradicating out of your water.

The important contaminants you’re more likely to need to take away from water are:

  • Viruses
  • Bacteria
  • Protozoa
  • Parasites
  • Chemicals 
  • Metals
  • Dirt / silt / sand
  • Microplastics

While water filtration and water purification programs are in a position to take away the above sorts of contaminants, not all filtration programs are able to eradicating all these contaminants from water. To select the very best water remedy technique, it would be best to take into account the place you’re touring and the types of water sources you’re more likely to have entry to.

Most water filtrations programs can take away most grime, sand, microplastics, micro organism, protozoa, and parasites from the water. However, solely these with finer filters will be capable to deal with viruses as effectively. And solely these with carbon filters will usually be capable to take away chemical compounds affecting the style or scent of the water.

For backcountry journey within the US for instance, the extra urgent issues are protozoa and micro organism, which most water filters ought to be capable to deal with. Viruses are mostly transmitted through human waste, and this transmission is much much less frequent within the US because of good waste administration practices and low inhabitants densities within the areas the place vacationers would possibly have to filter water sources.

Travelers to growing components of the world might also need to take into account a water purification system that may additionally take away viruses. Of course, these of you desirous to err on the facet of warning (not a foul factor), would possibly desire a full purification system no matter vacation spot.


What can’t a Water Filter Remove?

Water filters and water purifiers can’t take away each doable kind of dangerous contaminant from water. You will need to rigorously learn the specs of a specific water filtration product to make sure it removes the contaminants of concern for you.

It is essential to notice that water filters are usually NOT able to eradicating issues like:

  • Fuel oil
  • Toxic chemical compounds
  • Radioactive supplies

In eventualities like this, which usually are catastrophe associated, the CDC recommends utilizing bottled water.

Water filters for journey are additionally not designed to desalinate or filter seawater or ocean water.


Water Filter vs Water Purifier

You might come throughout the time period water filter and the time period water air purifier, and surprise what the distinction is. The distinction is generally all the way down to what it removes from the water.

A water filter is generally able to filtering out protozoa and micro organism, and has bigger pore sizes within the filter mesh. A water air purifier can even filter out protozoa and micro organism, however is moreover able to filtering out viruses that are a lot smaller.

Travellers within the United States will usually be extra involved with micro organism and protozoa reminiscent of Giardia and Cryptosporidium, which will be filtered out with a water filter. Travelers to much less developed nations might want to take into account viral dangers like hepatitis A, which require a air purifier.

These two sorts of filtration merchandise are usually grouped collectively and we will likely be protecting each of those merchandise in our information.


What Filter Mechanism Does It Use?

Water filtration units, because the title suggests, use a filter to wash the water. These filters are very fantastic, and the water usually wants some stress with a view to go by way of the filter itself.

Different filter programs have adopted completely different approaches to this. Three frequent programs are straw-based, pump-based, and gravity-based.

A straw-based system works like a ingesting straw. The filter is discovered inside a big ingesting straw like machine. You put one finish of the straw within the water to be filtered, and suck on the opposite finish. The motion of sucking by way of the straw creates detrimental stress which ends up in the water passing by way of the filter and into your mouth. This is an effective choice the place you could have common entry to water, however is finest suited to single particular person use. It can even require numerous effort to suck the water by way of the straw.

Examples of really useful straw-based filtration programs are the LifeStraw Go and Sawyer Bottle.

A pump-based system works utilizing some sort of pump to exert stress on the water and pressure it by way of the filter. This is an effective choice for filtering water for later use, and you may filter as a lot or as little water as required within the second. The drawback is that it might require numerous handbook effort to filter the water.

Examples of in style pump-based filtration programs are the Survivor Filter Pro and Grayl UltraPress.

A gravity-based system makes use of gravity to pressure the water by way of the filter. You add the water to be filtered to a bag, hold it up someplace with the filter on the backside, and gravity causes the water to go by way of the filter. This can take a while, and is extra in style for bigger quantities of water. This is an effective choice for a gaggle camp or for RV use the place you need to filter bigger quantities of water for a number of individuals.

An instance of a well-liked gravity-based filtration system is the LifeStraw Mission.


How Long Does It Take to Filter Water?

When evaluating a water filtration or purification system, you need to examine how lengthy it takes to filter the water. In most circumstances, producers ought to present an estimate for the way lengthy it takes to filter a certain quantity of water, say one litre or one gallon.

For instance, a gravity or pump-based system may be able to filtering 10 litres in a single hour.

For a straw-based system, the pace will depend upon how exhausting you suck on the straw. But filtration is pretty instantaneous.


How Easy is it to Use, Maintain, Clean and Store?

When it involves a product that’s designed to create secure ingesting water, you ideally need it to be as straightforward to make use of as doable. We suggest wanting on the instruction handbook for any product to get a really feel for what number of steps are concerned in producing clear water.

If a product has a sophisticated, multi-stage course of, there’s a greater chance that you’re going to get one thing improper, doubtlessly resulting in ingesting contaminated water. Ideally, the method ought to be easy and straightforward to recollect.

As effectively as ease of use, additionally, you will need to take into account how straightforward the product you select is to take care of, clear, and retailer. It ought to be straightforward to take aside for any cleansing, and there ought to be tips on how finest to retailer it between makes use of.

A water filter isn’t one thing you’re more likely to be utilizing on daily basis, so between journeys you need to be certain it’s one thing you possibly can pack away for subsequent time with out fear.


How Much Water Can it Filter?

Most programs for water filtration and purification have a restrict on how a lot water they’ll filter. Larger pore filters, reminiscent of these designed to take away micro organism and protozoa, are likely to have an extended lifespan than these with smaller pores that are designed for viruses.

So for instance, a purification filter that may filter out viruses would possibly be capable to do 100 – 400 litres earlier than the filter wants changing. A system for micro organism would possibly be capable to do 1000L+ earlier than it wants changing.

This is as a result of the way in which the filters work is that they really get blocked up by the stuff they’re filtering out of the water. Over time, all of the pores will likely be blocked and the filter will cease permitting water by way of. Smaller pores get blocked faster than bigger pores.

Some filter programs help you lengthen the lifetime of the filter by “back-washing” them. This entails forcing purified water by way of the filter in reverse to wash it out. This can considerably lengthen the lifespan of the filter.

Some water filter programs have completely different filter phases as effectively. For instance, there may be a pore-based filter for filtering out nasties, and a carbon-based filter for bettering the style. Often, the carbon-based filter may have a extra restricted lifespan. The excellent news is {that a} worn-out carbon filter doesn’t make the water much less secure to drink, though the style of the water may be degraded when it’s worn out.

The important factor is to determine how a lot water you’re more likely to have to filter in your journey, primarily based on period and variety of individuals. Then you possibly can see if the machine you’re selecting will likely be sufficient, and in the event you would possibly have to spend money on extra filters.


How Durable Is It?

Depending on the place you intend to make use of it, a water filtration system is more likely to be a critically essential a part of your package. Having entry to wash water is admittedly essential, and also you want to have the ability to depend on the product you’re shopping for.

Ideally the product may have been examined to resist a certain quantity of affect, each empty and full. If it shops water, you need to be certain it’s not going to leak. Out on the path, you need one thing that’s going to have the ability to deal with being dropped or bashed round a bit with out failing.

Definitely be cautious of something that has small fiddly bits of plastic which may simply break, as this might trigger a significant issue. We would usually suggest having a fall-back system, reminiscent of chemical purification tablets if you may be off-grid for some time, simply in case.


How Much Does It Weigh?

Weight is a vital consideration for any traveler. If you’re planning a again nation climbing journey the place you’re carrying every part in your again, then you’ll undoubtedly be fascinated about weight an ideal deal.

However, even vacationers with checked baggage don’t have infinite baggage allowances! So you’re unlikely to need to pack an enormous cumbersome water filtration system, or carry it with you if you end up out sightseeing.

The excellent news is that lots of the choices in the marketplace are light-weight and designed to be transportable, usually being not a lot bigger or heavier than a standard water bottle.


Does it Have Replaceable Parts?

Different filter designs will possible have completely different components which can be replaceable, and it’s value understanding what these components are and what the alternative prices are.

Most filter programs may have replaceable filters, however some might have extra components like hoses or seals that you’ll be able to substitute.

When evaluating costs of various programs, it’s value checking the completely different costs of those alternative components and their estimated lifespan so you could have an thought of a complete lifetime value.


Certification of Efficacy

For one thing as essential as secure ingesting water, it isn’t sufficient to imagine a producer’s claims of efficacy. Any producer of a water filtration or purification system that believes of their product ought to be keen to have it independently examined to an agreed commonplace. Ideally these exams will likely be offered in full so that you can take a look at.

There are two important requirements which can be used for water purification / filtration testing. The first is the EPA commonplace. This was developed by the US-based Environmental Protection Agency within the Nineteen Eighties, and offered a framework for testing micro organic water purifiers with a view to show in the event that they produced water that was secure to drink.

A more moderen testing framework, NSF P231, was launched by the worldwide organisation NSF (this used to face for National Sanitation Foundation, however right this moment it’s simply referred to as NSF). The NSF framework was developed primarily based on the EPA doc, however is frequently revised and up to date.

NSF P231 is the usual you need to be in search of at the least for filtration testing. It is a troublesome 10-day take a look at in a number of components, and a good producer ought to be capable to present proof that their machine handed the take a look at in full.

It is value noting that there’s additionally an much more strict commonplace, NSF P248, which some manufacturers additionally take a look at to for further peace of thoughts. This is just like P231, however was developed for testing US navy water purification programs to be used on navy operations. This one is much less frequent for consumer-focused filters, however if you would like the final word in peace of thoughts, take into account investing in a product which has met P248 testing necessities.

Note that there are different NSF testing requirements, together with NSF 42 and 53. These are primarily designed to check house water filters for style enhancements, moderately than to render them secure.

We would undoubtedly suggest investing in a filter that meets EPA and NSF P231 testing requirements, and which gives proof of the identical.


Cost Per Litre / Gallon

When you’re evaluating completely different water filters and purifiers, it may be exhausting to get an thought of how they evaluate from a price viewpoint.

One good strategy to evaluate is to see how a lot it will value you to filter one litre or one gallon of water utilizing the machine. To do that, you simply want the price of the machine and the quantity of water it might filter over its lifetime.

For instance, you would possibly spend 100 {dollars} on a tool that may filter 1,000 litres of water. 100 divided by 1,000 is 0.10. So this machine would value you 10 cents per litre.

Of course, if the machine has a replaceable filter which prices 25 {dollars}, your future value will drop. So over the overall lifetime of the product your general value may be decrease. However, calculating the preliminary value per litre or per gallon is an effective place to begin for comparability functions.


What Water Sources Does It Support?

Depending on the kind of journey you’re doing, you would possibly want a unique model of water filtration machine. For instance, in case you are primarily travelling in a rustic the place you simply need to filter the faucet water for security, then most units will work fantastic as you possibly can simply maintain them beneath the faucet.

However, in case you are planning a again nation journey that may require you to supply water from a stream or river, then you’ll need a tool that permits you to seize that water, particularly if the supply is shallow. This would possibly contain tubing and a pump, or another mechanism for capturing the water to be filtered.

The important factor is to choose a tool that’s able to working within the varied eventualities you’ll need to make use of it in.


What Temperatures Does It Work In?

It is admittedly essential to test what temperatures the machine you intend to purchase is able to working in. This is very the case in case you are planning on touring to a chilly climate vacation spot.

When the temperature dips beneath freezing, clearly this could trigger any water inside your filtration system to freeze. Some filters will likely be completely broken if this occurs, and so should not rated to be used in freezing climate circumstances.

Most units will work fantastic in heat climate, though do at all times test what temperature vary the machine is rated for and evaluate it with the temperatures you count on to come across when utilizing it.

Lifestraw Go_by_Laurence Norah

LifeStraw take a look at all their merchandise and publish their outcomes on their web site. The LifeStraw Go meets US EPA and NSF P231 ingesting water requirements for the removing of micro organism and parasites.

The important drawback of the LifeStraw is that it’s actually designed for single particular person use. The filtration occurs as you drink, so you possibly can’t filter water after which distribute it to others. So everybody would wish their very own LifeStraw. It additionally isn’t good for filtering water for makes use of aside from ingesting, for a similar cause.

However, as a ingesting water filter it really works very effectively so long as you don’t have to take away viruses, and the worth can be very affordable. We nonetheless use ours frequently after we journey.

One main benefit of the Sawyer Bottle in comparison with the LifeStraw Go is that it comes with a backwashing package. This is principally a syringe that you should utilize to pressure clear water by way of the filter in reverse, a course of referred to as backwashing.

This considerably extends the lifetime of the filter as a result of it unblocks the pores. Sawyer state that with common backwashing (after each journey ideally), the filter ought to final for no less than 100,000 gallons. That is principally a lifetime of use for most individuals, and it makes the Sawyer Bottle probably the most cost-effective water filters in our spherical up on a price per litre foundation.

The bottle itself can be comparatively light-weight, at 5.5oz (155g), and might maintain 34oz (1 litre) of water.

Grayl UltraPress

We got here throughout the Grayl vary of merchandise when researching a visit to Africa. We didn’t need to must be continually shopping for bottled water, however knew that the danger of water borne viruses was an actual concern. As such, we needed a filtration system we may depend on to totally purify water for ingesting.

In our case this was primarily going to be water sourced from faucets, so while it was usually clear to the attention, we had no thought what it may be carrying. To be on the secure facet, we figured a system that filtered out every part together with viruses was a good suggestion, which meant our LifeStraw Go wasn’t going to chop it.

We discovered the Grayl UltraPress met our wants. This appears like a water bottle, however has a intelligent constructed in-filter system which has you urgent the filter by way of the water type of like a French Press, with the clear water ending up in a chamber you possibly can drink from.

The Best Water Filters for Travel 2022 + Everything You Need to Know

There are a couple of benefits of the Grayl UltraPress. First, it’s able to filtering out all waterborne pathogens together with viruses. It does this with a mix of small pore holes and electroadsorption / ion alternate. There can be a carbon factor within the filter to take away style and odor.

Second, the press system implies that the purified water goes right into a chamber from the place it may be decanted into different containers. So you should utilize this for a number of individuals, for cooking, private hygiene and so forth. This makes it far more versatile in comparison with a straw-based system.

There are some downsides. The double-walled design and comparatively massive filter unit implies that the machine is somewhat heavy. It can even solely maintain 500 ml / 16.90z, though the bigger GeoPress mannequin holds 740 ml / 24oz

In addition, a filter which may filter out viruses usually has a shorter lifecycle.

Grayl Ultrapress_by_Laurence Norah-3

The Grayl Ultrapress filter is rated at 150 litres (40 gallons), so the price per litre is kind of excessive. In some locations, it would even be greater than shopping for bottled water. However, alternative filters should not too costly, so over the lifetime of the product the worth per litre will come down somewhat.

The bigger GeoPress is simply marginally costlier and might do as much as 250 litres (65 gallons) per filter, in order that does work out more cost effective general. However additionally it is bulkier and heavier.

Pressing the water additionally takes a little bit of effort. I discovered it best to place the entire unit on the ground after which push down, though it may be performed by hand on a desk as effectively. Grayl does suggest utilizing your physique weight to push it down, and the floor of the highest of the bottle that you just push on is designed to be comfy to do that and to resist the stress.

It’s simply fairly a bit of labor, and in my expertise took somewhat longer than the ten seconds Grayl suggests, even with clear water and a brand new filter.

It can be value noting that an electroadsorption / ion alternate primarily based filtration course of is somewhat completely different to straightforward filtration which depends on pore measurement. A pore-based system principally blocks the unhealthy issues. An ion primarily based system works a bit like glue – the unhealthy issues within the water like viruses keep on with the ions whereas the water passes by way of.

Unfortunately, over time, the ions can lose their cost and the filter can lose its effectiveness. Unlike a pore-based system, which blocks up and turns into un-usable when exhausted, there’s no straightforward strategy to inform when an ion-exchange system has misplaced its cost.
