While water filters are all the rage at the moment, with them being an obvious and great way to make sure you aren't getting any unwanted bacteria or other assorted filth from your tap water, they may not be the best way to clean up your H2O. The best way? Nanotechnology, of course.

Researchers are looking into using "tiny particles of pure silica coated with an active material" to get rid of everything from toxic chemicals to viruses from drinking water, making previously unpotable water drinkable for everybody. It's not clear how exactly the nanoparticles could be implemented as a replacement for filters, but it's a pretty solid idea, one that could have widespread positive effects if implemented properly.
