I've seen some household-sized water filter units advertised in the past. They filter all the water entering your home's drinking water system. The problem with those systems is that they're generally expensive to install and maintain, or at least more so than a portable water filter system.

As far as the odor of chlorine in water goes, it's the chlorine that is actually dissolved in the water that does the work. You won't smell it. The chlorine that doesn't dissolve is what you smell. If you put enough chlorine in contact with water to create a 2 PPM chlorine level and that chlorine doesn't dissolve into the water, you're not going to get 2 PPM results in the water... you might get 1 PPM, for example, and an odor of chlorine. Not ideal...
