    Since the people that these sand filters are directed toward are also commonly using wood burning fires (or dried manure), it would be a great touch to spend a little time looking into this further.

    I could easily image (and will pursue) a secondary filter that the water exiting the sand filter then goes through. It should be quite easy to replace the media and easy to do so on a daily basis. If it can improve water taste and quality, you’ve not only made the people healthier but also happier. There is value in that, too 😉
