Don't worry, I read a previous post about iodine, so I purchased the chlorine dioxide tablets instead. They work great, but I discovered the hard way that the four hours the tablets require to work is too long to wait.

The coffee filter trick didn't work too well, because it seems water has to be forced through the filter. Or maybe you have to wait a really, really long time for it to drip through.

I'll definitely switch from tablets to a water filter... although I'll keep the tablets for backup, as they do work well, and leave the water tasteless.
