- For a home that prefers a larger stated grain figure: The 50,000 grain Aquasure Harmony title also states a salt-based type and metered regeneration, giving you the largest grain figure among the two metered picks here. See pick 2
- For a buyer who wants a salt-based softener without a metered claim: The Kenmore 350 title names a salt-based type and a 32,000 grain figure, but does not state metered regeneration, leaving that decision to your own research. See pick 3

$699.00 (as of 10/17/2026 23:14 PDT - Details)

EcoPure EPH130 Whole House Water Softener & Filtration System
$699.00 (as of 10/17/2026 23:02 PDT - Details)

- No type or grains claimed, leaving the decision to the buyer
- It is a water conditioner, not a softener with a stated type

How we picked
This guide covers 6 water softeners and conditioners priced under $700, drawn from the catalogue. Each listing is compared strictly on the details stated in its title: whether it names a type, a grain capacity, metered regeneration, and any other specification such as flow rate or iron. The ordering rule puts listings with a stated type first, then those with a stated grain figure, then by the number of additional details named (metered, gallons, flow, iron, resin, bathrooms), and finally by the order in the pool file. No price amounts are used in the comparison, and no capacity is converted into household sizing.
How to choose
What an under $700 softener can state
In this guide, every listing is priced under $700, but the catalogue does not tell you how that price translates into performance. The only evidence is the listing title: it may name a type, a grain figure, metered regeneration, or other features like flow rate or iron. Use these stated details to compare, and read the maker's page and your own hardness kit for sizing.
Type as a title word
The title may name a salt-based softener, a shower unit, or no type at all. Salt-based units regenerate with salt and a brine tank; a shower type is stated for a specific application. When no type is named, you have less to compare, so you must decide based on the other stated details.
Grain capacity as the title prints it
Grain figures are the seller's own claim. This guide does not compute a household size from a grain figure; sizing for your home is read on the maker's page against a hardness kit reading of your own water. Compare picks on the number as printed, but never assume a larger number suits a larger family.
Metered regeneration as a title word
Some titles state metered, on-demand, or demand-initiated regeneration. That is a stated feature of the unit, but the catalogue gives no data on salt or water use during regeneration. Use it as one comparison point, not as a savings promise.
What this guide leaves out (and why)
This guide covers only what the listing titles state: type, grains, metered, and other named specifications. It does not cover drinking water safety, sodium content, plumbing installation, or certifications. Those questions belong to the maker's manual, a licensed plumber, and the official pages listed in the sources.
Questions
Which pick is the best for a home on a well that names iron as a concern?
None of the listings in this guide state iron in the title, so no pick can be tied to an iron claim. For well water, use a hardness kit to read your water hardness and read the maker's page for any stated capabilities. The EPA private wells page in the sources has official guidance for well owners.
Does this guide cover drinking water safety, sodium, or certifications?
No. The catalogue has no data for drinking water safety, sodium levels, or certifications. This guide compares only the details stated in each listing title. For those topics, see the EPA private wells and drinking water pages, and the Penn State Extension water softening article, listed in the sources.
How do I know what grain capacity my home needs?
This guide does not compute a needed grain figure. The grain number in a title is the seller's stated capacity. To size a unit for your home, read the maker's page and use a hardness kit to measure your own water hardness, then follow the maker's own sizing guidance.
Are these softeners easy to install?
This guide gives no installation advice. Installation depends on the specific unit and your plumbing. Read the maker's manual and consult a licensed plumber before any installation work.
Why do some listings have no type stated?
Some titles simply do not name a type, such as salt-based or shower. In this guide, those listings rank lower because the ordering rule prefers listings that state a type. You can still compare them on the details they do state, but you have less information from the title alone.
