Decision matrix: softener vs. conditioner vs. filter vs. RO
These four systems solve different problems, and many Valley homes use two of them. Compare what each one is for, what it can't do, the upkeep, and which certification to ask about.
| System | Purpose | What it does and doesn't do | Upkeep | Certification to look for |
|---|---|---|---|---|
| Salt-based softener (ion exchange) | Reduce scale from hardness in the whole house | Does: swaps calcium and magnesium for sodium or potassium on a resin bed. Doesn't: remove bacteria, particles, organic chemicals or radon, and it adds some sodium or potassium to the water. | Add salt or potassium; clean the brine tank; resin wears over the years; it rinses brine water to a drain when it regenerates | NSF/ANSI 44, the NSF standard for cation-exchange softeners. WQA's Gold Seal is another certification program. |
| Salt-free conditioner (e.g., TAC) | Reduce scale without salt, brine or a drain | Does: aims to change hardness minerals into tiny crystals that are less likely to stick. Doesn't: remove hardness minerals; UNL Extension says few conclusive studies confirm these devices work in homes. | Media replacement on the maker's schedule; no salt | NSF/ANSI 44 covers ion-exchange softeners, not conditioners, and NSF's standards list doesn't name one for them. Ask what independent testing backs the scale claim. |
| Carbon or whole-house filter | Chlorine taste and smell, sediment, some organic chemicals | Does: filters water where it enters the home. Doesn't: soften water or remove hardness. | Replace cartridges or media on schedule | NSF/ANSI 42 for taste and odor claims such as chlorine; NSF/ANSI 53 for health-related claims. Check that the listing names the contaminant you care about. |
| Under-sink reverse osmosis | Drinking and cooking water at one tap | Does: reduces total dissolved solids, and may reduce arsenic, lead and many organic chemicals, depending on the model's certification. Doesn't: treat the whole house, and it isn't effective for radon or some volatile chemicals. | Replace prefilters, postfilter and membrane on schedule; sends reject water to the drain (Goodyear's 2025 report says RO units can use up to 5 gallons to make 1) | NSF/ANSI 58. TDS reduction is the required claim; arsenic, lead and nitrate are optional claims that must be listed for the model. |
Based on NSF's standards guide, University of Nebraska-Lincoln Extension G2275 and University of Arizona Extension AZ1498. NSF notes that certification to a standard covers the claims listed, not every possible contaminant. A water test tells you which problem you actually have.
A common Valley setup is a softener for the house plus RO at the kitchen sink. Prices for each system are in our water softener cost guide, and your city's hardness is in the Phoenix water hardness guide.

How matching works
You fill out one short form. We share your request with up to 5 independent companies that serve your area and handle the service you picked. We only send requests to companies that give us an active Arizona ROC license number and proof of liability insurance. We ask companies to respond promptly; they may contact you to answer questions, test your water if needed and give you a quote. You decide whether to hire them. Read the details on how it works.
Water Softener Connect is not a contractor and never performs work. The company you hire sets its own prices and warranties. Before you sign, you can confirm their license with the Arizona Registrar of Contractors.
Contractors who want to receive requests can learn more on our page for pros.
