G'day Anthony,
Grayl have this infomration on their website: "WHAT SHOULD I DO IF MY GRAYL FREEZES? We advise changing the Purifier Cartridge after two (2) freeze/thaw cycles. GRAYL conducted freeze/thaw tests in an independent lab to determine the effect of freezing your GRAYL. After a single freeze/thaw cycle, the Purifier Cartridge maintained performance. However, after three freeze/thaw cycles the Purifier Cartridge suffered a drop in performance below acceptable levels."
Hope that helps!

Weight and filter details1 answer
Does the quoted weight of the bottle (0.309 kg) includes the filter? Plus, if you do not use up the filter on one hike, dry the bottle out, can you keep using it later? Does drying out a partly used filter reduce its lifespan?
Robert - Sydney Olympic Park, NSW(4 years ago)
G'day Robert,
Yes, the quoted weight is the complete bottle - I've just double check on my scales here. The Grayle Ultralight Filter has a lifespan of 150L, so it's unlikely you'll use the filter up on one trip. There's absolutely no issue to use your bottle off and on, just keep a round track of how many liters you have filtered in the back of your mind so you know when you're due for a replacement.

Dam water?1 answer
I go trekking with my horse, would this filter dam water for me to drink.
Bettina - Burnbank (4 years ago)
G'day Bettina,
Yes I think you'll be fine with Dam water, the filter is designed to remove waterborne pathogens, as well as filter out particulates (i.e. silt, microplastics, etc.). The activated carbon effectively adsorbs chemicals, pesticides, heavy metals, flavours, and odours. I can't think of anything else that would sneak into Dam water, so you should be fine.

Does the water still need to be treated1 answer
Will I still need to treat the water with tablets or does this eliminate the need to carry them?
Michael - COLLAROY PLATEAU(4 years ago)
G'day Michael,
The Grayl bottle will knock everything out for you, it will remove 99.9999% of viruses, bacteria and protozoan cysts. You won't need to carry tablets with this, they essentially do everything the tablets do plus more.

Ultralight vs Geopress1 answer
How does this product compare against the Grayl Geopress? What are the main similarities and differences between the 2?
Jia Lin - Alexandria(5 years ago)
G'day Jia,
The Grayl Ultralight and Geopress will do the same job of filtering your water and getting rid of any nasty stuff, the capacity is the only difference. The Ultralight has a 473mL capacity, while the Geopress is 710mL.

Will this filter work for Giardia? 1 answer
Hello! I just wanted to get someone to verify if this system would be effective for Giardia? I have been hiking in the Vic Alps and have had to treat my water with tabs and wait the recommended 2 hours minimum for Giardia, so I am after a filter that would cut down that time frame? I look forward to your reply. Thank you!
Jay - Wollongong(5 years ago)
G'day Jay,
The Grayl filters out 99.99% of viruses, bacteria, and protozoan cysts. Giardia comes under the category of protozoan cysts so the Grayl will provide quick effective treatment of water for your travels.

Can I filter water in the bottle and then tip the filtered water into another container as well as drinking directly from bottle.1 answer
I am travelling through South America and want to be able to use this as a drinking bottle and also to transfer the filtered water into my water system within my backpack. Can this be done?
Sherryl - Yaroomba 4573(5 years ago)
G'dau Sherryl,
You sure can, you can drink the filtered water directly from the bottle, or tip it into another receptacle with no issues.

Can it be used as a regular drink bottle when there is no need to filter?1 answer
If I'm taking this on a hike can I use this as my primary water bottle, and top it up with clean water I brought with me without using the filter? Or is it better to bring another drink bottle, and just use this to filter water?
Chris - Adelaide(5 years ago)
G'day Chris,
You can, but the bottle can't be used if you are removing any of the filtering components. Its capacity is 475ml, and given the size of the bottle vs the amount of water you can carry, its probably not worth it if you dont need to filter your water. Hope that helps!

Does the filter remove Fluoride?1 answer
Wondering if this bottle removes fluoride? Thanks
Rachel - Bundall(5 years ago)
G'day Rachel,
Grayl makes no mention of Fluoride in their details on chemicals filtered so it's unlikely that it's included. The full list can be found here :) Cheers

Will this bottle filter parasites1 answer
I am traveling to Vanuatu and am interested in a water filtration bottle. Will this bottle also get rid of some parasites. If not are there other bottlers that will.
Louka - Ocean Shores(5 years ago)
G'day Louka,
The Grayl Ultralight purifier will filter out 99.99% of viruses, bacteria, and protozoan cysts. Most parasites fall under the protozoan cyst category (e.g. Giardia, Cryptosporidium and Amoebae). So this bottle should do the trick for the parasites you'll encounter in Vanuatu (it's usually Giardia that gets people sick there).

Large size??1 answer
Will you be stocking the larger size model soon?
richard - newcastle(6 years ago)
G'day Richard,
The Grayl Geopress is yet to land here in Australia, but our supplier has indicated they should be available in July / August. Best bet will be to send us an email then and we can confirm their price and available once they land here.

Will it turn sea water fresh and drinkable?1 answer
If it removes and treats water as you say then the final question is..will it treat seawater removing the salt and resulting in fresh drinkable water.?
Oliver - Bayswater(6 years ago)
G'day Oliver,
Thanks for getting in touch, the Grayl Water Purifier is designed to remove viruses and bacteria from water. To be able to drink sea water you'll need a desalinator of some form. There are a number of ways you can achieve this in an emergency situation, but in general, we'd suggest sourcing fresh water as desalinating can be a fairly long arduous process.

I am travelling to Morocco. Is it ok to fill the Grayl bottle with tap water?1 answer
I am travelling to Morocco. Is it ok to use the Grayl with tap water in the cities and or well water?
Angela - Coomera, Australia (6 years ago)
G'day Angela,
You'll be fine using a Grayl bottle in Morrocco as it removes 99.9999% of viruses, disease-causing bacteria, and protozoan cysts. It will remove dirt from well water but the dirtier the water, the faster the filter will get clogged up and require cleaning or replacing. If you're not sure how long you'll need it to last it might be worthwhile taking a spare cartridge.
Tim - Snowys(6 years ago)
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...
Jillian - Vic Pt (7 years ago)
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.
