Subsequent I seemed on the price, contemplating each the upfront price and the way the everyday lifetime of a unit and substitute cartridge prices would add up over the course of a 12 months.

For many individuals, the first function of a filtered water bottle is to enhance the style of in any other case secure faucet water, in order that they will get pleasure from being extra hydrated all through the day.

As employees author at Outside Life, most of my time evaluating merchandise is spent out within the subject, getting my arms soiled. That was not the case with the very best filtered water bottles; as an alternative, most of my time was spent attempting to trace down info on what testing had been completed to validate a given filter’s capacity to filter any variety of contaminants, from PFAS to result in chlorine to giardia. For a number of merchandise, I needed to question to trace down the testing outcomes.
The Epic water filter had a few of the finest transparency of any of the filtered water bottles I checked out. They’d a chart on the product web page on the web site itemizing the share removing of assorted contaminants, and a hyperlink (considerably buried however moderately simple to search out) to much more full testing results. This can be overkill for people merely searching for some higher tasting water, however when you’ve got a particular contaminant you’re involved about in your effectively water or municipal water provide, this chart is important.
One thing else I appreciated about Epic is that they’ve a reduction arrange on their web site for ordering their filters as a subscription. One of many greatest causes that filtered water bottles get a foul rap is that folks don’t change out their filters typically sufficient. Should you’re utilizing a filter that’s meant to wash out contaminants like lead or PFAS, outdated filters may very well cease working. Filters that don’t filter out a lot past chlorine can find yourself with micro organism constructed up inside them over time, making them much less wholesome than in the event you had been simply consuming faucet water.
Within the subject, the Epic was additionally one of many filtered water bottles I grabbed for most frequently. The Nalgene housing felt acquainted in my hand and I preferred that the straw was extra of an oblong form than a circle. Functionally, it has about one ounce much less capability than it states (because of the house contained in the bottle the filter is taking over), however that’s a minor quibble. Whereas this filtered water bottle had a noticeably dangerous style in the beginning of testing, it improved quickly and was on par with the remainder of the filters in my check by the second day.
Merely put, the Epic Water filter is a simple to make use of system that protects towards just about all the pieces. The one Achilles heel that I ran throughout throughout my evaluation of their knowledge was that their filter solely removes 99.95 % of viruses, whereas 99.99 % is the usual set by NSF P231, which is the usual used for well being and sanitation. In case you are touring to part of the world that has a recognized difficulty with norovirus or different virus contaminants, err on the facet of warning and select a filter that’s recognized to take away these contaminants out to the proper decimal level, such because the Grayl GeoPress or the MSR Guardian.
Greatest for Worldwide Journey: Grayl GeoPress

- Filter Kind: Electroadsorption and ultra-powdered activated carbon
Execs

- Requires some elbow grease to run by way of the filter
In case you are touring to part of the world the place norovirus or rotavirus (or hepatitis A, or enterovirus) are recognized to be a difficulty, the Grayl GeoPress is the filtered water bottle for you. Not solely is it the one filtered water bottle I checked out that was able to dealing with viruses, however its counterpart, the UltraPress, additionally survived my check of the best backpacking water filters. In that check, I ran water filters by way of more and more gnarly water situations to see which had been nonetheless able to filtering on the opposite facet. Whereas gradual on the finish, the Grayl simply squeaked by.
Not like the opposite filtered water bottles in my check, the Grayl GeoPress doesn’t depend on you to suck the water by way of the filter to operate. There are a number of benefits to this. First, it’s rather a lot much less annoying to drink out of than different filtered water bottles. It can be shared with different relations, together with babies, with out having to fret about whether or not or not they will create sufficient suction to make the filter work.
This filter works extra like a french press. You fill the underside reservoir with water, after which push the filter down on high of it. This works fairly effectively, but it surely does require some severe leverage. Sometimes I put the reservoir on the ground after which use my physique weight to push down on high of the filter. That’s wonderful in my kitchen (and would even be within the backcountry) but it surely’s potential that you’d be much less excited to run by way of this operation in the event you had been in a public setting, like an airport or a restaurant. Have in mind your deliberate use earlier than making a remaining buy.
Whereas Grayl doesn’t at present have their testing specs listed on-line for customers to examine, they had been capable of ship me knowledge to confirm the leads to the above desk.
Longest Filter Lifespan: Sawyer Personal Water Filtration Bottle

The Sawyer Mini (the filter inside their private water filtration bottle) has lengthy been a mainstay of backpacking and thru-hiking. It has a wonderful popularity for preserving individuals secure from micro organism and protozoa (though not viruses) and is as efficient as something I checked out in decreasing the style of chlorine in faucet water. Of all of the filtered water bottles I examined, this one was the closest to consuming out of an everyday straw, by way of its design and its circulation fee. It is usually the one filter making one particular declare: 100,000 gallons.
I’m going to degree with you: I don’t suppose backpackers are getting 100,000 gallons (370,000 liters) out of the Sawyer filters, or any filter for that matter. There’s simply an excessive amount of muck within the water they’re working with, too many different elements to account for, together with the potential to break or drop the filter. And whereas the unique Sawyer filter was the one one in my check of the very best backpacking water filters to wrap the check with a sooner circulation fee that it began with, the Sawyer Mini did expertise a noticeable slowdown in circulation fee, even after backflushing.
However that’s when it’s challenged with a few of the grodiest water, stuffed with muck and sediment, that I might discover. Should you’re filling your bottle out of the faucet, it could very effectively final that lengthy. Whereas nobody but has examined certainly one of Sawyer’s filters out to 370,000 liters, Messiah College did check the Sawyer out to 230,000 liters and located that it was nonetheless eradicating micro organism and protozoa previous the necessities set by the EPA. Should you drank 4 liters of water a day, it could take you over 150 years to drink that a lot water, so this looks like as shut as you will get to a lifetime assure for a water filter.
After all, this assumes common care. The Sawyer Private Water Filtration Bottle comes with a backflush plunger that you’ll want to carry onto, and use often, to be able to protect the circulation.
