Difference between GEOPRESS and ULTRAPRESS1 answer
What are the differences between the Grayl Geopress and Ultrapress?
Josie - Mile End, SA(8 months ago)
G'day Josie,
The only real difference is the capacity/size of the bottles and the filter life. The Ultrapress is designed to be smaller and a bit more lightweight, therefore has a smaller filter. In terms of how the bottles function and the actual filtration levels, they're exactly the same.
Hope that helps.

Use as normal drink bottle1 answer
If using as normal drink bottle with safe water (filling from top), does it 'use' the filter (ie wasting the longevity of the filter). Just wondering if it can be the normal drink bottle with filter for emergency refills
Emily - Melbourne, VIC (3 years ago)
G'day Emily,
The short answer is yes, if you're 100% sure that the water source isn't contaminated then you can fill the bottle from the lid opening that you'd normally just drink from. The filter itself will remain in place if you do this, it will just mean that you don't use it to push to water through from the dirty to clean section of the bottle. It's not something that will give the best overall life and longevity to the filter though, so if you're travelling and wanted to do this it won't be a worry, but if you're wanting this as your everyday water bottle that is occasionally used as a filter bottle then we wouldn't really recommend this.

Filtering poison 3 answers
Hi just checking if you know wether it will filter out poisions such as 10/80 and other poisions used by farmers and national parks and wildlife
Steve Miller - Oak flats NSW (3 years ago)
G'day Steve,
Grayldoesn't specify whether the Geopress will filter out poisons like 10/80, but I've included their exact wording below so you can have a look.
Filters: particulates (i.e. silt, microplastics, etc.); activated carbon effectively adsorbs chemicals, pesticides, heavy metals, flavours, and odours
Leece - Snowys(3 years ago)
I contacted Grayl Australia about the question and this is what they replied: "That’s actually a tricky one to answer! Though Grayl in the US have carried out extensive tests as to the efficacy of their filters on many waterborne impurities such as bacteria, heavy metals, and volatile organic compounds, etc…, as far as I can see, they have not specifically tested for Sodium Fluroacetate (1080). So I can’t give you a definitive and scientifically-backed answer on that one! If you would like to see their full lab results from the filter tests they can be found HERE As you must be aware, anecdotally, 1080 is supposedly “safe” once it has broken down and dissolved in water, and traces are virtually undetectable in water samples taken 12-24 hours after bait application, but there are many like you who are understandably sceptical. We are over in NZ, and it is used extensively for pest control here, just like in Aus, and so again all I can offer is anecdotal assurances that many backcountry hunters are out there with Grayl bottles and filling them from streams in catchment areas where 1080 has been used upstream. Whether this is 100% safe, I am not able to scientifically say! Sorry I haven’t really been able to answer your question with anything concrete, and thank you for re-sparking our interest to actually get them tested locally for their ability to filter out Sodium Fluroacetate and its broken down components, so that we can then say with confidence to our Aussie and Kiwi backcountry users that their filters will protect them from the potential harm caused by the use of 1080. Hope this helps, and if you have any more questions, feel free to send them through."

Filtering2 answers
Saw a You-tube clip that says it filters out Fluoride. Is this true
Christine - 6064(3 years ago)
G'day Christine,
I've had a look through all of the information we can get from Grayl and they make no claims about the filter being able to filter out Flouride. As far as I know its fairly tricky to remove fluoride from water, so I'd dare say this won't get rid of fluoride sorry.
Leece - Snowys(3 years ago)
It says in the supplied booklet the chemicals filtered are chlorine, benzene, chloroform . I'm not sure if it removes them I hope this may help

Use without filtration1 answer
Hello. Call Can the Geopress be used as a normal water bottle without the filtration device?
Alex - Coburg North(4 years ago)
G'day Alex,
The short answer is yes, if you're 100% sure that the water source isn't contaminated then you can fill the bottle from the lid opening that you'd normally just drink from. The filter itself will remain in place if you do this, it will just mean that you don't use it to push to water through from the dirty to clean section of the bottle.

can you filter hot tea, that you feel may not have been boiled for long enough ?1 answer
can the geopress filter hot tea, that you feel may not have been boiled long enough to kill off any bacteria etc ?
carol - perth(4 years ago)
G'day Carol,
I've just double-checked the user manual, and Grayl specify that you shouldn't use water greater than 50'C, so if you did want to filter tea it would need to be lukewarm before you pour it into the Geopress, using water that is over 50'C may cause damage to the purifier cartridge. The filter will also be likely to filter out some of the tea itself, as tea will generally have some degree of sediment depending on how it is steeped/made.
