How we picked
This guide covers 11 Aquasure listings from a pool whose rule is listings whose stated brand is Aquasure. The shortlist is the whole pool: every pick is an Aquasure listing. Listings are compared on the details each title states: type, grain capacity, gallons, flow rate, metered regeneration and iron. Ordering runs by a stated type first, then by a stated grain figure, then by the number of other details the title states, then by the order of the pool. The top pick states a salt-based type, 70,000 grains, metered regeneration and iron, the most stated details here. Live prices are printed beside each listing, so the comparison is on stated details and live prices at the moment of reading. This guide makes no performance claims.
How to choose
Harmony Series salt-based softeners and what the titles state
9 of the 11 Aquasure listings in this guide carry Harmony names and state a salt-based whole house softener with a grain figure. 7 of those 9 state metered regeneration, and 3 of the 9 name iron. Every detail in the comparison comes from the listing title; nothing is assumed from the model name.
Metered regeneration as a title word
7 of the 11 titles in this guide state metered or automatic digital metered control. A title that names metered regeneration states that regeneration is set off by usage rather than a fixed schedule. The catalogue does not state how often any unit regenerates, and no salt or water use figure is given.
Iron named in the title and well water
3 listings in this guide name iron in the title: the 70,000 and 50,000 grain Harmony listings and the 32,000 grain Water Softener Plus. An iron-named listing is a listing whose title names iron; the catalogue gives no level of iron it handles. The EPA private wells page in SOURCE PAGES is where reading about well water begins.
Grain capacity as the title prints it
Every Harmony listing states its own grain figure, from 32,000 up to 70,000 grains. These are the seller's stated figures, not a computed size for a household. Sizing for a home is read on the maker's page against a hardness reading of your own water, as the Penn State Extension page in SOURCE PAGES explains.
Salt-free Serene listings and what a salt-free title means
2 listings carry Serene names and state salt-free water conditioning and descaler systems, one with an 800,000 gallon figure and one with a 10 GPM figure. A title that says salt-free is a salt-free listing; this guide makes no claim about how it compares with ion exchange.
What this guide leaves out (and why)
This guide compares listings on the details each title states: type, grains, gallons, flow rate, metered regeneration and iron. The catalogue holds no data on drinking water safety, sodium, plumbing, certifications, durability or performance, so none of those appear here. 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 those topics, so this guide makes no claims about any of them. Read the maker's manual and ask a licensed plumber about installation. The EPA and Penn State pages in SOURCE PAGES are the official places to start for private wells and drinking water.
How are these Aquasure listings ranked?
Ranking follows the stated details of each title: a named type first, then a stated grain figure, then the number of other details the title states (metered regeneration, iron, gallons, flow rate), then the order of the pool. No claim is made about performance.
What does metered regeneration mean in a listing title?
A title that names metered or automatic digital metered control states that regeneration is triggered by usage rather than a fixed time schedule. The catalogue does not state how often a unit regenerates or how much salt or water it uses.
Which Aquasure listing has the largest stated grain figure?
The Harmony 70,000 grain listing is the only title here with a stated figure above 64,000. A stated grain figure is the seller's own number; sizing for a home is read on the maker's page against a hardness reading of your own water.
What is the difference between the Harmony and Serene titles here?
Harmony titles state salt-based whole house softeners with grain figures. Serene titles state salt-free water conditioning and descaler systems, one with an 800,000 gallon figure and one with a 10 GPM figure. The catalogue gives no comparison of their effects.
