I am making a portable water filtration device for campers and hikers for my year 12 final project and need some people to fill out a quick survey. Would be greatly appreciated.

I would happily complete your survey, but I will not because it requires my email address. Sorry.
Cheers,

Apologies Peter I didn't realize this was an issue. I've now changed the survey so it doesn't require email addresses.

Lidman
Are you actually making it or theoretically designing such a device? for assessment reasons, ie, not making it at all.
Do you have a knowledge of microbial biology to cater for the unseen bugs and have a method of negating them which would be included in the device?

Campers can use a device far larger than a walking backpacker, so a device which suits one for camping volumes would not easily fit in a backpack with all the other gear, I carried 24kg in mine. Every bit of weight or rather lack of, counts as a positive. Anything H2O from river or high country water which I later drank, I always boiled for a period of time first and left to cool before ingesting.

I am unsure what is trying to be made here. But I have tablets that I add to water that kills the bacteria. OK it does not filter the water and remove the "debris", so I am unsure of what the OP is wanting to design.

The OP is probably not sure either, that is the purpose of the survey.

Being connected with a yr 12, what used to be called "Technical Design and Development" requires for assessment, that the paticipant surveys the field of consumers so a degree of research is/can be shown to have been done, ie, legitimises the work to the end assessor.
Unfortunately the people, this is the third such request, don't tell all, with the approach and the responders, us, don't necessarily know what it is ultimately intended.
The participant/student may already know and have trawled the googly thing for related info. There is a vast mutitude of these devices already marketed and that info would swamp any which we provide.
We use them but don't have specs or performance data or responses for most other factors, we just use them and they seem ok. No tummy bug yet? For a period of time I assessed such work and the survey is just one part to satisfy the assessing teacher who usually isn't savvy in the area. They come from ALL areas of so called Technology.
Just answering survey questions doesn't really do much for the student who may go on to invent something new because they have ability. Great well thought out comments will assist even if they aren't direct answers to survey questions.
PS, I feel sorry for some students because they are required to select something or concept to investigate for course work and often are not provided with sufficient guidance by their teacher.
