I've run mine on a tub of water with a little bit of chlorine bleach. It'll sterililze it. Run it for 24 hours then drain, rinse the filter, refill and set the filter back up. Add a double dose of dechlorinator and run it for another day.
Some are afraid of bleach, but it's just chlorine. Dechlor will deal with it nicely.
