Los Angeles / Water guide / 2 of 3
Match treatment to the water goal
A practical guide for your home. This is utility context and equipment guidance, not an individual water test.
Three different jobs
Whole-home filtration can address specified taste, odor or sediment concerns when the chosen media and flow are appropriate. A conventional ion-exchange softener reduces measured hardness. A kitchen reverse-osmosis system treats water at a separate drinking-water tap. One does not automatically replace the others.
Start with a measurement
Measure untreated water hardness when selecting a softener. Review household flow, pressure, available space, drain access and installation permission before choosing a system.
A TDS meter alone does not identify individual contaminants or establish safety. Ask for the exact model’s performance documentation before relying on a reduction claim.
