First Need XL = 624g
Sawyer Mini = 40g
this and this alone is why the sawyer is so popular ,but when this happens and you end up getting 6 litres of water from the nearest farmhouse to chug the rest of the journey well that 40g weight just turned into 3,4,5? kilos , it may have been safe to drink but i wasnt about to neck 1l of it and find out wheras if the filter made the dirty water clean at least i know it is doing its job.now i would really like to run a side by side test
It's a tough one with water.
When i hike here in Greece in the summer months it seems like i spend more time looking for water than i do hiking (not the case but it seems that way), i've carried in more than 12 litres of water on remote hikes in the summer here as i couldn't say 100% that i'd find a water source anywhere on the route.
Even when i'm back in the UK because i'm choosy from where i take my water, that has meant long detours.
As i said previously, IMO there is no "one solution" for clean safe water that's practical to carry around when hiking, so it really comes down to using some common sense.
For me this mean in and around large populated areas i won't take water from a river, to be honest even when i'm hiking around Derbyshire, the lakes etc i still won't take water from low land rivers unless i had to.
Sounds difficult, but i can't say as i've ever really had a problem finding someone to give me some water in low land areas especially around areas of high population.
I've asked and gotten water from farms, petrol stations, pubs, public toilets, parks and houses, it's a bit of a ball ache asking but it's better than taking water from low land rivers running through highly populated areas (to me).
I have several mates that don't filter, some boil some don't even bother doing that, none have gotten ill yet.
I never used to bother filtering or boiling for years, i must have drank hundreds of litres of untreated water for years, it's only after i got very very ill from what i strongly suspect was contaminated water that i started boiling, then filtering.
It used to be thought that you had to drink at least 10 cysts for it to affect you, it's now thought that only 1 will do the job.
So you have to be unlucky enough to scoop up 1 or more out of a water source that's thousands if not millions of litres.
To put that into perspective a cyst will be around 0.4 to 0.6 micron, a human hair is around 100 micron in width.
You cannot see cysts without a microscope, so judging how safe water is to drink by the colour doesn't mean anything, that's really the point i am trying to put across.
The only exception to this would be if you knew exactly the size of the detritus that was colouring the water.
It's also pointless comparing how one filter removes colouring from one water source, to another filter not removing colouring from a completely different water source.
As the sample water is completely different from a completely different location it's pointless to compare.
It's like saying i drank water from a mountain stream and didn't get ill so all water around the world must be safe.
Even then IF another filter removes the colouring it doesn't mean the water is safer to drink than the one that doesn't IF the one that doesn't is working correctly.
As i say i have absolutely zero loyalty to Sawyer, i use their products because right now they're the best solution for me.
I just think that because some bloke off the internet says that his brand X has removed some colouring from some other completely different water source it doesn't mean that:
a/ The water wasn't safe to drink
b/ That brand X is better
Lets compare apples to apples.
If brand X removed colouring that the Sawyer wasn't able to, then it's obvious that brand X is filtering more efficiently than the Sawyer, but lets try the same water source before jumping to conclusions.
If i was the op then:
1/ I wouldn't take water from a river
2/ If i even slightly suspected the Sawyer i'd beg, borrow or buy another to try it against
