On the planet of purifying ingesting water, there are numerous alternative ways of performing the bushwalker’s miracle of water into w… nicely, water… and making it secure to drink. The hiker’s alchemy of with the ability to cut back your backpack weight by accumulating water alongside the best way and never find yourself with some type of gastro is a superb revelation – it’s additionally straightforward to do. I’ve been utilizing a Grayl UltraPress water purification filter for a few months earlier than penning this gear evaluation and right here’s what I discovered:
The commonest methods of treating ingesting water for bushwalking and mountain climbing are:
- Tablets – eg. Micropur
- Drops – eg. Aquamira
- Filters – Like this one or Sawyer Squeeze, MSR or Katadyn
- Boiling
- UV Mild – eg. Steripen
When water filters first hit the out of doors gear market, they tended to be cumbersome and heavy. Fortunately, these points are persevering with to be addressed by the main water filter producers similar to Katadyn, LifeStraw, Platypus, Sawyer Squeeze, MSR and Grayl.
The factor that actually struck me by the Grayl UltraPress air purifier stand out from different choices is how straightforward it’s to make use of. Merely scoop up water, push the filter down (it takes a little bit of effort) and bingo – 500 ml of water that’s good to drink. No tricksy attaching hoses, rigging issues as much as dangle or ready half-hour for it to work.
It’s additionally the type of easy system that I’d wish to take travelling anyplace I didn’t belief the water from a faucet.
The Execs
- Easy
- Prompt
- Slimline Design
- Enormous gremlin and bug-killing functionality = virus, micro organism, protozoa, microplastic, silt, sediment, chemical compounds and heavy metals
The Cons
The primary draw back for me is the load at 354 g (additionally they do an Ultralight at 309 g).
The filters will final for 350 x 500 ml presses and disposing of the filter cartridge (80 g). Grayl are within the strategy of organising a trade-in service with TerraCycle (as at March 2022), so fingers crossed that doesn’t take too lengthy to occur – I wouldn’t wish to see the filters having to go to landfill.
At round $140 AUD, you’ll wish to take excellent care of your filter bottle to get probably the most out of it. There’s a wee little bit of stuff you might want to know, just like the significance of drying out your filter and storing it (brief time period – on the observe and long run – at residence)
