How I examined these filtered water bottles

For the sake of protected ingesting water, two buddies and I ventured out to a freshwater supply in Southern California. We have 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 sequence of 4 tiny swimming pools of water. Of the 4 water holes, we settled on testing the bottles within the one which seemed 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 listing in accordance with their directions. I crammed every bottle from the identical water gap and tasted the water from every bottle on web site. I then drank from the bottles one after the other and poured some water from every to see how clear it seemed. I used to be able to drink gallons of water if want be, and preserve ingesting till I discovered the very best reusable water bottle.

How I rated these filtered water bottles

I thought of 5 essential standards when utilizing every reusable water bottle: filtering and filter capability, supplies, style, ease of use and cleanup. These are all components it’s best to think about when searching for a filtered water bottle — you will need to buy one which fits the exercise you intend to make use of it for.

As an example, if I used to be searching 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 go away 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 substitute filters?

Supplies: What’s the bottle fabricated 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, have been there any remnants of mineral odor or chemical tastes comparable 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 movement price?

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


The pure water I examined the bottles in already seemed comparatively clear, however after I poured a bit from the Geopress water purification bottle, I used to be shocked at how crystal-clear it seemed. 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 compounds, particulates (like dust and sand), heavy metals and micro organism and viruses.

The Geopress water air purifier is fabricated from BPA-free polypropylene, a sturdy sort of plastic. The vast 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. Unquestionably, the Geopress is the very best filtered water bottle to maintain you hydrated with clear water on a backpacking journey on account of its intense filtering mechanism and sturdiness. 

This Grayl bottle additionally provides comparatively simple clean-up, an essential issue in the event you’re utilizing pure water. I actually preferred that the opening of the Geopress water filter bottle is vast sufficient to suit ice cubes and my complete hand into it, which means I might truly unravel the bottle with a sponge. Simply ensure that to totally dry the filter bottle earlier than storing it: For those who retailer the water air purifier whereas it is moist, the inside portion and outer parts suction collectively and it is then troublesome to tug the 2 items aside.

The Astrea One filtered water bottle filters out a formidable suite of heavy metals and chemical compounds, 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 high quality.

The physique of the Astrea One filtered water bottle is fabricated from chrome steel, and the lid is fabricated from thick BPA-free plastic. The water bottle filter inserts snugly into the underside aspect 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 standard wide-mouth chrome steel water bottle, making it tremendous simple to scrub: The bottle opening is vast sufficient to suit a typical 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 provides a subscription service so that you always remember to switch your filter. The water bottle filters are $12 per substitute filter and ought to be bought each two months in the event you use your filter water bottle repeatedly — 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 Select filtered water bottle is clear ingesting water, that is for positive. Sawyer Merchandise provides all types of clean-water gadgets, however this purifying water bottle specifically makes use of a double-filtration system: The inside “Foam Adsorption Expertise” removes heavy metals, chemical compounds, pesticides and viruses, whereas the outside micron water filter removes micro organism, protozoa, cysts, dust and sediment. 

The Sawyer Choose bottle is fabricated from BPA-free, food-grade silicone, and the inside is foam. The assorted caps, in addition to the exterior micron water filter, are fabricated 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 searching for a handy journey water bottle, although, is that this filter bottle won’t ever return to its dry weight when you’re on foot. It is inconceivable to squeeze the entire 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 would’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 the entire water out of the water filter bottle, it’s essential give it a critical squeeze — even roll up the bottle from the underside, just 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 technique 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.

Brita is understood for its faucet and pitcher filters, however the firm additionally makes plastic and chrome steel filtered water bottles. In response to Brita’s web site, these bottles aren’t meant for outdoor use — they’re meant for simply filtered faucet water, just like the Astrea bottle — however this bottle additionally filtered pure recent water simply high quality. The Brita filtering water bottle makes use of an activated carbon filter, which is extraordinarily porous and pulls contaminants, comparable to chlorine and particulates. 

Brita’s filtered water bottles are available in plastic and chrome steel. It is BPA-free and comparatively sturdy, however I would not take this bottle filter bottle on a backpacking journey. It will suffice for day hikes, nonetheless, in the event you crammed 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 aspect of the cap.

Regardless of being some of the in style water-filtering merchandise available on the market, 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 by the filter. That is to not say the Lifestraw Go is not protected to drink from — the particles have been in all probability simply sediment — however it did produce a comparatively sturdy mineral style in comparison with the opposite bottles on this listing.

The Lifestraw Go is fabricated from BPA-free plastic all through. General, the Lifestraw Go feels fairly sturdy. I choose the sturdiness of chrome steel, however it’s light-weight and comes with a carabiner, so it could make a great backpacking water bottle.

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

Waterwell claims its double-stage filtration system removes 99.9% of waterborne pathogens, however based mostly 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 for clear water. 

The bottle and cap are comprised of BPA-free plastic and really feel simply as sturdy as a plastic bottle ought to. The filter, nonetheless, is hooked up to the straw by a flimsy rubber tube, which could possibly be the perpetrator behind the poor filtering. The water tasted bitter, however I could not fairly place the style — sulfur, perhaps. Despite the fact that I did not actually need to, I took a pair extra sips (and likewise spat these out) to ensure it really 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 simple to make use of, with the identical setup as many of the different bottles on the listing: bottle, cap, filter. The water bottle filter detaches simply and the bottle opening is giant sufficient to insert a typical dish scrubber.
