Post date:



Whether or not you are taking quick hikes for a few hours or voyage into backcountry wilderness for days on finish, you by no means wish to end up thirsty, and you need to all the time have entry to scrub water. As any avid open air fanatic already is aware of, an excellent filtered water bottle for clear water is an important piece of journey gear. In any case, you do not wish to tote gallons of purified bottled water, which is an environmental plague, to not point out heavy and costly.

Whereas many sources of groundwater and faucet water are completely secure, it is by no means well worth the threat to drink water you are simply not sure about. Even when a water supply seems clear, it may very well be non-potable water contaminated with viruses, micro organism, protozoa or different microorganisms invisible to the human eye. Should you’ve ever been sick from ingesting water, you recognize that waterborne micro organism are not any joke. And regardless of the Protected Ingesting Water Act, faucet water can nonetheless comprise contaminants akin to lead, chlorine, arsenic, pesticides and even particles from malfunctioning wastewater remedy. As an alternative, why not take into account giving a water filter bottle a spin?

Some causes chances are you’ll wish to say goodbye to utilizing a plastic water bottle or disposable water bottles and put money into a filtered water bottle to maintain you hydrated:

To that finish, I examined six filtered water bottles to seek out the most effective filtered water bottle you’ll be able to belief to offer you clear, secure water, indoors or out.

How I examined these filtered water bottles

For the sake of secure ingesting water, two associates and I ventured out to a freshwater supply in Southern California. We had been fortunate to discover a tiny trickle of a waterfall within the Rancho Sierra Vista/Satwiwa Wilderness space within the Santa Monica Mountains, which culminated in a collection of 4 tiny swimming pools of water. Of the 4 water holes, we settled on testing the bottles within the one which appeared the least stagnant (and had the fewest bugs and tadpoles).

The day earlier than the hike, I cleaned and prepped every water filtration bottle on my checklist based on their directions. I stuffed every bottle from the identical water gap and tasted the water from every bottle on website. I then drank from the bottles one after the other and poured some water from every to see how clear it appeared. I used to be able to drink gallons of water if want be, and maintain ingesting till I discovered the most effective reusable water bottle.

How I rated these filtered water bottles

I thought of 5 necessary standards when utilizing every reusable water bottle: filtering and filter capability, supplies, style, ease of use and cleanup. These are all components you need to take into account when on the lookout for a filtered water bottle — you will wish to buy one which fits the exercise you intend to make use of it for.

As an example, if I used to be on the lookout for a filtered bottle to take backpacking, I would not select the Brita. I additionally would not put money into the Grayl Geopress if I solely wanted a bottle for faucet water.

Filtering: What filtering mechanism was used and the way effectively did the bottle filter dangerous contaminants, micro organism and viruses, and different unpleasantries out of the presumably non-potable water? Did the water bottle filters depart any particles within the water after filtering? Water “after filtering” means the water that comes out of the ingesting spout or filter straw. Are there alternative filters?

Supplies: What’s the bottle made from? Chrome steel or plastic? If plastic, is it a BPA-free bottle? How sturdy is the bottle?

Style: This one’s fairly apparent. How did the water style? Particularly, had been there any remnants of mineral odor or chemical tastes akin to a chlorine style?

Ease of use: Was the bottle simple to prep and put collectively? Was it simple to get water into the bottle? How was the circulate charge?

Cleanup: After use, what are you purported to do with the bottle? How simple is it to scrub the bottle and ensure it is prepared in your subsequent journey?


The pure water I examined the bottles in already appeared comparatively clear, however after I poured a bit from the Geopress water purification bottle, I used to be shocked at how crystal-clear it appeared. Though I suppose I should not have been stunned, as Grayl’s heavy-duty filtering and water purification system is designed to filter out protozoa, chemical substances, particulates (like filth and sand), heavy metals and micro organism and viruses.

The Geopress water air purifier is made from BPA-free polypropylene, a sturdy kind of plastic. The huge base diameter of the water air purifier offers it a sturdy really feel, and it is apparently designed to resist 10-foot drops onto concrete whereas it is stuffed with water. Certainly, the Geopress is the most effective filtered water bottle to maintain you hydrated on a backpacking journey as a consequence of its intense filtering mechanism and sturdiness. 

This Grayl bottle additionally presents comparatively simple clean-up, an necessary issue should you’re utilizing pure water. I actually appreciated that the opening of the Geopress is huge sufficient to suit ice cubes and my total hand into it, which means I might truly unravel the bottle with a sponge. Simply be sure that to totally dry the bottle earlier than storing it: Should you retailer the water air purifier whereas it is moist, the interior portion and outer parts suction collectively and it is then troublesome to drag the 2 items aside.

The Astrea One filtered water bottle filters out a powerful suite of heavy metals and chemical substances, together with lead, benzene, mercury, copper, chlorine and extra. The web site says you should not use this filter bottle with water that’s “microbiologically unsafe or of unknown high quality,” however I used it in pure freshwater and I turned out superb.

The physique of the Astrea One filtered water bottle is made from stainless-steel, and the lid is made from thick BPA-free plastic. The water bottle filter inserts snugly into the underside facet of the lid and locks in, giving the bottle an total sturdy really feel. 

The water I scooped from a pure water gap appeared to magically flip into bottled spring water contained in the Astrea filter bottle. If the Astrea One bottle did not have its filter in place, it could simply be a traditional wide-mouth stainless-steel water bottle, making it tremendous simple to scrub: The bottle opening is huge sufficient to suit a normal dish scrubber contained in the lid, and the lid has an additional opening the place the filter attaches to ensure you hit all of the nooks and crannies. 

Astrea presents a subscription service so that you always remember to interchange your filter. The water bottle filters are $12 per filter and needs to be changed each two months should you use your filter water bottle usually — however contemplating most individuals drink about 2 liters of water a day, that ought to provide you with loads of gallons earlier than you want a brand new filter.  

Sawyer Merchandise

Water that comes out of the Sawyer Choose filtered water bottle is clear ingesting water, that is for positive. Sawyer Merchandise presents all kinds of clean-water devices, however this bottle specifically makes use of a double-filtration system: The inside “Foam Adsorption Expertise” removes heavy metals, chemical substances, pesticides and viruses, whereas the outside micron water filter removes micro organism, protozoa, cysts, filth and sediment. 

The Sawyer Choose bottle is made from BPA-free, food-grade silicone, and the inside is foam. The assorted caps, in addition to the exterior micron water filter, are made from BPA-free plastic. The micron water filter itself is a hole fiber membrane. The bottle is squishy, however it nonetheless feels comparatively sturdy. 

One downfall for backpackers, although, is that this bottle won’t ever return to its dry weight whilst you’re on foot. It is not possible to squeeze all the water out of the bottle, so anticipate it so as to add some weight to your pack after the primary use. 

This Sawyer bottle requires an preliminary prep to take away any foam adsorption materials that might’ve gotten knocked free throughout packaging or delivery. When you prep the bottle, the water filtration course of requires 10 seconds of compacting the bottle to work the froth adsorption characteristic. To get all the water out of the bottle, you’ll want to give it a severe squeeze — even roll up the bottle from the underside, much like the best way you roll up a toothpaste tube when it is getting low. 

As a result of this filter water bottle has so many elements, it is fairly troublesome to scrub. There is no method to get your hand or a brush contained in the bottle, and the froth inside makes me fear that the within can by no means get utterly clear and dry. Nevertheless, the web site does say that it isn’t essential to utterly dry the Sawyer Choose filter water bottle, as the froth can also be designed to forestall mildew and micro organism progress.

Brita is thought for its faucet and pitcher filters, however the firm additionally makes plastic and stainless-steel filtered water bottles. In keeping with Brita’s web site, these bottles aren’t meant for out of doors use — they’re meant for simply filtered faucet water, just like the Astrea bottle — however this bottle additionally filtered pure contemporary water simply superb. The Brita filtering water bottle makes use of an activated carbon filter, which is extraordinarily porous and pulls contaminants, akin to chlorine and particulates. 

Brita’s filtered water bottles are available in plastic and stainless-steel. It is BPA-free and comparatively sturdy, however I would not take this bottle on a backpacking journey. It will suffice for day hikes, nonetheless, should you stuffed it up with faucet water first (use with pure water at your individual threat). 

The Brita filtered bottle consists of simply three elements: the bottle itself, the flip-top cap and the filter, which properly locks into place on the underside facet of the cap. It is easy to place collectively and requires nearly no prep — simply rapidly wash the bottle and run the filter underneath scorching water earlier than your first use. As a result of the bottle accommodates minimal elements, it is fairly simple to scrub.

Not advisable


Regardless of being one of the vital standard water-filtering merchandise in the marketplace, the Lifestraw Go didn’t meet my expectations for filtering. The double-stage filtration features a hollow-fiber membrane and a carbon capsule, but this was the one bottle that produced water with particles after passing via the filter. That is to not say the Lifestraw Go is not secure to drink from — the particles had been in all probability simply sediment — however it did produce a comparatively sturdy mineral style in comparison with the opposite bottles on this checklist.

The Lifestraw Go is made from BPA-free plastic all through. Total, the Lifestraw Go feels fairly sturdy. I favor the sturdiness of stainless-steel, however it’s light-weight and comes with a carabiner, so it could make an excellent backpacking water bottle.

The Lifestraw Go has three easy elements (bottle, cap and filter — 4 elements should you rely the carbon capsule contained in the filter), and the preuse prep is straightforward: Simply run clear water over the carbon capsule. Any time you utilize the bottle, let the water sit for a couple of moments to prime the hollow-fiber membrane filter.

Waterwell claims its double-stage filtration system removes 99.9% of waterborne pathogens, however primarily based on the style of the water that got here from this bottle, I would not be so positive. I did not really feel or see any particles like I did with the Lifestraw Go, however the style alone was sufficient to make me cautious of bringing this bottle into the backcountry. 

The bottle and cap are created from BPA-free plastic and really feel simply as sturdy as a plastic bottle ought to. The filter, nonetheless, is connected to the straw by a flimsy rubber tube, which may very well be the offender behind the poor filtering. The water tasted bitter, however I could not fairly place the style — sulfur, perhaps. Although I did not actually wish to, I took a pair extra sips (and in addition spat these out) to verify it actually tasted the best way I believed it did. 

Regardless of its poor filter attachment and bitter style, the Waterwell does have some good properties. It is easy to make use of, with the identical setup as a lot of the different bottles on the checklist: bottle, cap, filter. The filter detaches simply and the bottle opening is giant sufficient to insert a normal dish scrubber.
