Commuters must have

Great water bottle for anyone spending high volumes of time commuting, or working on sites where water is limited. I have an E-spring water filter in my home & this would have to be the most comparative product I have found to an above sink filter. I highly recommend this for those who spend high volumes of time on public transport or travel to various sites for work. This is even great for office environments where the filtered water is always a bit dodgy tasting. I have had so many people fascinated & asking me about this product. Remember to air this out. It gets a bit stinky. Highly recommend this product.

Fantastic Piece of Kit

I don't usually review products but this thing is the exception! Simple to use and the water tastes as clean as any bottled mineral water. I was a bit skeptical about the stagnant puddles of mosquito water within a gorge where I hiked and I could barely see the bottom! After a quick press the water was sediment free, clear and tasted great! The pressure to filter is firm but not too hard to press!

Great for Himalayan trek

My family used this product to filter water on a recent trek in the Khumbu area of Nepal. These days the lodges all have taps so it is easy to use this to fill other bigger bottles for the day. It was super easy to use and most importantly it worked - if it works in Nepal it will work anywhere.

Grayl Ultralight Water Purifier & Filter Bottle - A very heavy empty filter bottle

I have used this Grayl water purifier bottle to filter the rain water at the Great Ocean Road campsites for drinking and cooking. The empty Grayl water purifier bottle is heavy to carry with you on the trail (hike).It's fairly pricey as well. If weight is an issue, the better option is to treat the water with tablets.

Gets the Job Done

I purchased the Grayl for a recent trip to the Himalayas. My main reason one the ability to filter water in the Grayl and pour it into a separate bottle. This means once you find a water source you can fill up for the day, far better than something like a lifestraw where water is only filtered when drinking. Beautiful design, very easy to use. Filters around 400ml each time.

Reliable and effective

I bought this from Snowy's (with the usual fast and free delivery) for a hike where water was available, yet needed to be boiled to avoid any nasties. With just a small hiking stove, the idea of boiling 4 or 5 pots worth of water didn't seem like fun. I chose the Grayl for two reasons: no batteries required (and thus no chance of flat batteries or electrical faults), and it's declared effectiveness (all the 99.9999%'s of this and that referred to in its blurb). Filling the water bottles of four hikers took about 5 minutes, and a little (but not much!) effort. I reckon any reasonably able-bodied person can muster the strength required to use it, even kids, especially with thoughtful positioning of their body-weight. Besides cleaning "clear" water of bugs and heavy metals, its nice to know that in a pinch, the Grayl could filter, and remove most sediment from, muddy water as well (something the UV purifiers can't do).


How do you know when the filter is no longer viable? Are replacement filters available?1 answer

Considering for use for 2 of us in Morocco for a month...

G'day Jillian,

Good question. The best thing to do is head over to Grayl's website and have a read through their FAQ's as it's not a simple yes or no answer, but assuming you're filtering 2 litres of water a day per person, one cartridge would get you through a month of travel. New cartridges are available here and they're pretty small so carrying a spare isn't a hassle.
