How we picked
The pool holds 9 listings whose titles name iron. All 9 are included. Picks are ordered by whether the title states a type, then a grain capacity, then the number of other details the title states, then by the order of the pool. Two listings state metered regeneration and a grain figure, so they lead. Iron appears only as a title word, never as a promise of removal. All comparisons are made on the stated details and live prices, following the rule that the title's word is the only evidence.
How to choose
Iron as a title word, not a promise
Every listing in this guide has the word iron in its title. That word is the seller's label; it does not tell you how much iron the unit can handle or whether it removes iron. For private wells and iron in water, the EPA private wells page and a licensed professional are the places to read more.
Salt-based, salt-free and dual tank in the title
The title names one of three types here: salt-based, salt-free, or dual tank. Salt-based units regenerate with salt and a brine tank; salt-free conditioners are sold without one; dual tank systems have two tanks. This guide does not compare how these types perform.
Grain capacity as the title prints it
The grain figure is the seller's own number as printed in the title. It is not a sizing recommendation for a household. To size a softener, read the maker's page and take a hardness reading of your own water. The Penn State Extension page explains hardness in grains per gallon.
Metered regeneration as a title word
Two listings in this guide state metered regeneration in their titles: the Aquasure Harmony 70,000 Grains and the Aquasure Harmony 50,000 Grains. Metered means a unit regenerates after a set volume of water. This guide makes no claim about salt or water savings from metered regeneration.
What this guide leaves out (and why)
The catalogue has no data for hardness levels, salt or water use per regeneration, flow at the tap, pressure drop, sodium, contaminant removal, plumbing, or certifications. Those decisions are read from the maker's manual, a licensed plumber, and the official pages in Sources.
Questions
What does it mean that a listing title names iron?
It means the seller put the word iron in the title. This guide does not claim that the unit removes iron or handles a certain iron level. For well water and iron information, see the EPA private wells page, which lists common well contaminants and steps to protect a well.
Does this guide cover drinking water safety, sodium, plumbing or certifications?
No. The catalogue has no data for those topics. The maker's manual, a licensed plumber, and the official pages in Sources are where to read about them. For private wells, the EPA private wells page is a starting point.
How are the picks ordered?
Picks are ordered by whether the title states a type, then a grain capacity, then the number of other stated details, then by pool order. The Aquasure Harmony 70,000 Grains comes first because it states type, grains, and metered regeneration, with the largest grain figure. No claim is made about removal or performance.
Why are there 9 picks?
The pool holds 9 listings whose titles name iron. All 9 are included in this guide. No near-duplicate folding was needed because each distinct model is a separate listing, even where the same brand appears in multiple grain capacities.
Can a salt-free unit soften water?
This guide does not compare types. Salt-free conditioners are sold without a brine tank, but the guide does not state how they perform or how they differ from ion exchange. The title of the NuvoH2O listing says salt-free and citrus-based, but the guide makes no claim about softening.
