How we picked
The pool held 16 listings whose titles name metered, on-demand or demand-initiated regeneration. Each pick was read from the listing title alone: type, grain capacity, flow rate, iron, resin and metered regeneration. Picks are ordered by whether the title states a type, then by whether it states a grain capacity, then by the number of other details the title states (flow rate, iron, resin, dual tank), then by the order in the pool file. From the pool, 12 picks were chosen, keeping one listing per model size where the same series appeared in several sizes. The picks are compared on stated details and live prices only, never by price. No hardness, household sizing, salt use, regeneration frequency or installation data is in the catalogue.
How to choose
Metered regeneration as a title word
Every pick in this list has a title that names metered, on-demand or demand-initiated regeneration. In general terms, a metered softener regenerates after a number of gallons have been softened rather than on a timed schedule. The Penn State Extension page on water softening describes demand-control models this way. Sizing for your home still comes from the maker's page and a hardness reading of your own water, not from the title alone.
What the title states beyond metered
Every title here also prints a grain figure. A few print extra details: two Aquasana listings state their flow rate in gallons per minute (16.6 and 15.5), two AFWFilters listings name 10 percent crosslink resin, and the Aquasure 70,000 listing is the only pick whose title names iron. Two picks name a second tank. Compare these details side by side with the live price on this page.
Grain capacity as the title prints it
Each pick's grain figure is the seller's own as printed in the title, from 40,000 to 96,000 grains. The largest stated figure is not automatically the right one for your home. The maker's page and a hardness reading of your own water are where sizing is read; the Penn State Extension page explains hardness units such as grains per gallon.
Dual tank listings and a second tank
Two picks name a second tank in the title: the Fleck 9100 SXT 80,000 and the AFWFilters Fleck 9100 64,000. A dual tank listing is one whose title says two tanks, which some buyers look for when they do not want a gap during regeneration. This guide compares only what the titles state.
What this guide leaves out (and why)
The catalogue holds no hardness level for your water, no salt or water use per regeneration, no regeneration schedule, no sodium figure, no contaminant removal data and no certification details. This guide therefore does not cover those points. The maker's page, a licensed plumber and the official pages in the sources are where those questions are answered.
Questions
What does metered regeneration mean in the titles here?
The titles name metered, on-demand or demand-initiated regeneration. In general terms, a metered softener regenerates after a number of gallons have been softened rather than on a timed clock. The Penn State Extension page on water softening describes demand-control models. Sizing for a home is read on the maker's page and a hardness reading of your own water.
Does this guide cover drinking water safety, sodium, plumbing or certifications?
No. The catalogue has no data for those points, so this guide does not cover them. The maker's page, a licensed plumber and the official pages in the sources, such as the EPA private wells page and Penn State Extension, are where those questions are answered.
What is the largest stated grain figure among these picks?
The Discount Water Softeners Genesis 2 title states 96,000 grains, the largest figure in this list. Grain figures in the titles are the sellers' own. Sizing for your home comes from the maker's page and a hardness reading of your own water, not from the largest figure alone.
Which pick names iron in the title?
Only one: the Aquasure Harmony Series 70,000 listing names iron alongside metered regeneration. The title does not state an iron level or any removal figure. For well owners, the EPA private wells page is where caring for a private supply is discussed.
How were the picks ordered?
By whether the title states a type, then a grain capacity, then the number of other details (flow rate, iron, resin, dual tank), then the order in the pool. The 12 picks are compared on stated details and live prices only.
