Is it expensive?

Do you have to spend a lot of money to be properly prepared?

So let me ask you a little bit about what you've got here.

These are some water filters.

So you just fill it up and it filters it and you just drink it out the bottle?

So this almost looks like a petrol can or something.

So dirty water goes in one end, clean water comes out the other.

And then this thing, which almost looks like you should be making tea with it.

Now, as Lee said, you don't have to spend a lot of money here.

That small personal water filter is less than $20.

But the one for the home is more than $215.

And the large fuel can type retails at nearly $440.

And that's just your water supply.

Tom is keen to stress that the most important thing here is knowledge.

One of his courses will set you back around $200.

And come to think about it, if he's the expert, what does he carry around with him?

This is not your normal first aid kit?

So is that the kit within a kit?

Yeah, it is, yeah.

That sort of everyday carry is becoming more and more popular.
