Still a new technology

This is quite a new invention, and I personally would be careful until it's developed and tested further, and especially until its effectiveness against viruses has been tested. But it's certainly very promising, and of course much better than untreated water.

At the Engineers Without Borders (Australia) conference, Tony Flynn discussed the possibility of making a series of filters - say, 3. If each one removes 99% of E. Coli, that would give a 99.99% removal. However, this hasn't been tested yet.

Water passed through a brand new filter looked pretty murky (on the Catalyst program) but this didn't seem to concern Tony Flynn. I don't know if this changes over time. I'd be concerned about this as microbes tend to be carried on small particles. Although these particles are probably from the filter, not from the water that was originally put in.

I would think that at this stage, cloth filters combined with solar water disinfection would be more effective (that's my prediction, anyway). The output of this filter could also be treated with solar water disinfection... this is all "unverifiable" of course as it's ideas and personal conversations, but I'll be interested to see if more research is done. --Singkong2005 02:59, 23 February 2006 (UTC)[reply]
