Very interesting. I'd like to a see a practical, in-the-field setup of this.

There doesn't seem to be one and instead it is just telling us how trees and plants filter water before it enters the tree itself. Yeah, that's interesting but I'm not sure it helps a person who wants to get a drink of water right now though maybe we can developer filters which mimic the biological process some time in the future.

Alternatively, these used to be commonplace in Cuba. Just a bit of limestone shaped into a cone. THey were often placed in cabinets designed to hold them. Porosity would be similar to ceramic filters. Back when it was discovered that yellow fever came from mosquitoes a lot of these were destroyed as potential breeding grounds. :

I'll just stick to boiling it.

Boiling water to remove contaminants requires a great deal of fuel to heat the water.
Lies .... just pick it up off the ground, the fuel was only going to rot any way. There is plenty of fuel ... and it's "renewable".

Not to mention that fire will be utilized or cooking, heating, drying or disenfecting so why not take advantage of that resource by using it to boil water.

Nothing wrong with natural water filteration , but to cut to the chase we have purchased 7 Seyshelle water filters.
The only filter in the world I would consider purchasing.

Be very careful in selecting water filters. I did a quick search on that company and it appears that the address resolves to the front of a car repair place (Google satellite view). There is also this review on Amazon:

Amazon.com: J. Black "adpng"'s review of Seychelle Water Filter Pitcher

Broward Testing Labs (their source of lab data) looks like a small business in an industrial park near where I used to live. From the Hazmat sign over their door, I suspect their testing is not centered around water filtration.

The only filters I trust are doultons made by Fairey ceramics.
