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 listing in response to 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 preserve ingesting till I discovered one of the best reusable water bottle.

How I rated filtered water bottles

These are all components you need to take into account when searching for a water air purifier bottle — you will wish to buy one which fits the exercise you propose to make use of it for.

For example, if I used to be searching for a filtered bottle to take backpacking, I would not select the Brita. I additionally would not spend money on the Grayl Geopress if I solely wanted a bottle for faucet water.

Filtering: What filtering mechanism was used and the way properly 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 alternative filters?

Supplies: What’s the bottle product of? 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 similar to a chlorine style?

Ease of use: Was the bottle straightforward to prep and put collectively? Was it straightforward to get water into the bottle? How was the circulation fee?

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

The Geopress water air purifier is product of BPA-free polypropylene, a sturdy kind of plastic.

Regardless of being probably the most well-liked 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 Lifestraw filter. That is to not say the Lifestraw Go is not secure to drink from — the particles had been most likely simply sediment — but it surely did produce a comparatively robust mineral style in comparison with the opposite bottles on this listing.

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 certain. 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 constructed from 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 may very well be the offender behind the poor filtering. The water tasted bitter, however I could not fairly place the style — sulfur, possibly.

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 many of the different bottles on the listing: bottle, cap, filter. The water bottle filter detaches simply and the bottle opening is massive sufficient to insert a normal dish scrubber.
