Good invention but has to be made free for the poor kids

There could be donation events or funded programs to give them away maybe. And I wonder if they could be shared and the filter still last as long.

I feel like if you invent something like that then you have a moral duty to give it to the world. Maybe you can sell it to survivalists but maybe release the patents so it can be made available to those who truly need it.

Honestly, I think twenty bucks is a good price to pay for clean water for a year. It's less than I pay for a month.

Does anyone know how it works? i think there is a filter in there against the parasites but how do you get rid of viruses without heat or chemicals?

To the OP: do you understand what "free" means. It's impossible to make it free. What you are asking for is that someone other than the end user pay for it. There is a VERY important distinction here. Free colege and free healthcare do not exsist in any country either.

So why don't they buy one . . . cheap bastards !!!

I know the inventors of this.. Their son in particular
