A basic dual filter system will get rid of silt, turbidity and chlorine. To clean up the rest you'll need RO. I bought from Home Depot a GE four stage RO for under 300 bucks with a 24 gallon per day capacity. It comes with a three gallon tank, all the interconnecting tubing, auto shut off, dispenser, mounting brackets, and an indicator that blinks when it's time to change the RO element. If you brew in the kitchen. Everything fits under the sink. Along with the RO, I bought two GE dual filters to prefilter the water going to the RO filter, and a 10 gallon tank. Summer time, the water here is terrible. Lots of sulfer, chlorine, alkaline, loaded with iron. I use two 10s and a .5 micron filter with a carbon polisher in the prefilters to keep the more expensive RO filters clean. The system is reliable, easy to install, uses standard size filters, produces consistently pure water, and has paid for itself.
