<If that's true, then shouldn't my water bill have gone up 3 to 9 times

I assume that you only filter your drinking and cooking water.

Most of your water is used bathing/showering, flushing the toilet, washing
your dishes, watering your lawn, and (maybe even) washing the sidewalk in
the summer! (gasp)
