How we picked
This guide covers 6 priced water softeners and conditioners, each sold with a live price under $800. The picks are ordered first by whether the title names a type, then by whether it states a grain capacity, then by the number of other details the title states (gallons, flow rate, metered regeneration, iron, resin, bathrooms), and finally by the order the listings appear in the pool. Under that rule, listings that name a type and a grain capacity rank ahead of the one salt-free listing that states neither. All picks are compared on the details stated in each listing title and on their live prices. No listing is ranked by price, popularity or the size of its grain figure; a larger stated grain figure is not better for every home. Sizing for a household is read on the maker's page against a hardness reading of your own water.
How to choose
Grain capacity as the title prints it
Five of the 6 picks state a grain capacity in their titles: 40,000, 48,000, 48,000, 50,000 and 64,000 grains. The figure is the seller's own, printed in the listing title. Sizing a softener for a household requires a hardness reading of your own water; the Penn State Extension page on water softening explains how hardness is measured in grains per gallon and how ion exchange units work. Use the stated grain figure as a comparison point, not as a size your home needs.
Metered regeneration as a title word
Five of the 6 picks name metered regeneration in their titles, and one of them says on-demand. The Penn State Extension page describes demand-control models that regenerate after so many gallons have been softened, as opposed to timed models. When a title names metered regeneration, that detail is stated by the seller; this guide does not promise a salt or water saving.
Iron, wells and what the title names
One listing in this pool, the Aquasure Harmony Series 50,000 Grains, names iron in its title. The title does not state an iron level or a removal claim, and this guide makes none. Well owners can read about private wells on the EPA pages listed in the sources.
Salt-based or salt-free in the title
Five picks are salt-based ion exchange units whose titles name a brine tank or a metered control head. The NuvoH2O Manor is the only listing whose title says salt-free, and it adds the word citrus-based. A salt-free listing is a listing whose title says salt-free; this guide does not state that it softens water or compare how it works with salt-based units.
What this guide leaves out (and why)
The catalogue these listings come from holds no data on hardness removed, salt or water used per regeneration, sodium levels, contaminant removal, plumbing or installation steps, pressure drop, warranties or certifications. This guide compares softeners only on the details each listing title states. Installation is a question for the maker's manual and a licensed plumber.
Questions
Does this guide cover drinking water safety, sodium, plumbing or certifications?
No. The catalogue has no data on drinking water safety, sodium, plumbing requirements or certifications, and this guide makes no statements about them. Read the maker's page for a listing, ask a licensed plumber about installation, and see the EPA private wells and drinking water pages in the sources for official information.
How is a grain capacity used when buying a softener?
The grain figure in a listing title is the seller's stated capacity. A softener is sized against a hardness reading of your own water, expressed in grains per gallon; the Penn State Extension page on water softening explains that measurement. No grain figure in this guide is turned into a household size or a number of people.
What does metered regeneration mean in a title?
A listing whose title says metered or on-demand names that form of regeneration. The Penn State Extension page describes demand-control models that regenerate after so many gallons have been softened, unlike timed models. This guide quotes the title's wording and never promises a saving in salt or water.
Which pick names iron in its title?
The Aquasure Harmony Series 50,000 Grains listing is the only pick whose title names iron. It states no iron level and this guide makes no removal claim. Well owners can read the EPA private wells pages in the sources for official guidance.
Why is the salt-free listing placed last?
The ordering rule ranks listings that state a type and a grain capacity ahead of listings that state a type but no grain capacity. The NuvoH2O Manor states a salt-free type but no grain figure and no other details, so it is placed after the five salt-based picks.
