Ultralight Water Purifier & Filter Bottle

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.

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.

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.

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!

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

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).

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.

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.

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. 

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.
