How we picked
This guide covers every priced water softener or conditioner with a live price in the under $900 window. The pool holds 8 listings, all salt-based. Each pick is compared on the details stated in its listing title: type, grain capacity, metered regeneration, iron, resin, and any other named feature. The ordering rule ranks picks first by whether the title states a type (all do here), then by whether it states a grain capacity, then by the number of other details the title names (gallons, flow rate, metered, iron, resin, bathrooms; most first), and finally by the order in the pool file. Live prices are shown on the page but never ranked.
How to choose
Salt-based, salt-free or dual tank in the title
All 8 listings in this price window are salt-based ion exchange softeners, as their titles state. Salt-based units regenerate with salt and a brine tank, as the titles describe. None of the listings here are salt-free or dual tank, so if you are looking for those types, this guide does not cover them.
Grain capacity as the title prints it
The grain capacity is the seller's own figure, printed in the listing title. In this list, the figures range from 40,000 to 70,000 grains. The maker's page and a hardness reading of your own water are where sizing is read, as the Penn State Extension page explains. This guide never computes a size for a household.
Metered regeneration as a title word
Three listings here name metered regeneration in their titles: the AFWFilters Fleck 5600 SXT, the Aquasure Harmony Series, and the Fleck Whole House 64k. Metered, or on-demand, regeneration is a feature that some buyers look for, but this guide does not state how often a unit regenerates or what it saves.
Iron, wells and what the title names
Three listings name iron in their titles: the Aquasure Harmony Series, the Kenmore 420, and the DURAWATER Iron Blaster. A listing whose title names iron is just that, a listing whose title names iron. This guide never promises iron removal. For well owners, the EPA private wells page is a source for testing and safety information.
What this guide leaves out (and why)
The catalogue has no data on water hardness, household sizing, salt or water use per regeneration, regeneration schedules, sodium, contaminant removal, pressure drop, valve brand, tank size, dimensions, weight, warranty length, or installation details. This guide compares only the details stated in each listing title and the live prices shown on the page.
Questions
Does this guide cover drinking water safety, sodium, plumbing or certifications?
No. This guide does not cover drinking water safety, sodium, plumbing, or certifications. The catalogue has no data for those topics. For questions about your water quality, the EPA private wells and drinking water pages are official sources. For installation, the maker's manual and a licensed plumber are the places to read about it.
How are the picks ranked?
Picks are ranked by whether the title states a type, then by whether it states a grain capacity, then by the number of other details the title names (gallons, flow rate, metered, iron, resin, bathrooms; most first), and finally by the order in the pool file. Price is never a ranking factor.
What does 'not stated by the seller' mean?
When a listing title does not mention a detail, such as metered regeneration or iron, the guide writes 'not stated by the seller.' It does not guess a value. The absence of a detail is not a claim that the unit lacks it, only that the seller did not state it in the title.
Can I compare these softeners by price?
The page shows each live price with its clock time, but this guide never ranks by price. Prices change, so the guide compares only stated details. The under $900 window means every pick has a live price within that range at the time the pool was read.
