Water Softener, Whole House Filter or Reverse Osmosis?

Name the goal

Hardness, visible particles and a particular drinking-water contaminant are different treatment questions. Describe the desired result before comparing equipment packages. Ask which observation or test supports the proposed treatment.

Understand softening

An ion-exchange softener addresses calcium and magnesium hardness. Its presence does not prove removal of a particular chemical contaminant or disinfection of the supply. Review capacity, flow, regeneration and salt requirements for the actual application.

Understand filtration

A sediment filter targets particles within its rating. Carbon and other media have different reduction claims and operating limits. Ask about the exact cartridge or media, documented claims, replacement interval and pressure loss.

Understand RO

A point-of-use reverse osmosis system typically serves selected drinking-water fixtures. Compare its documented contaminant reductions, production conditions, tank or tankless layout and maintenance. A total-dissolved-solids reading does not substitute for every safety test.

[NSF explains treatment standards](https://www.nsf.org/consumer-resources/articles/standards-water-treatment-systems); certification claims must be checked for the exact product and reduction. Review filtration and RO installation. Call (323) 916-2854 to discuss the project.
