On this page
Quick answer
- Harmony series: 32K, 48K, 64K and 72K grains, $539.99 to $799.99.
- Fine-mesh versions are rated by Aquasure for up to 10 ppm iron.
- Harmony Lite cabinet model: 34,000 grains from $489.99.
- Flow rate, certifications and base warranty term are not published.
- Best for budget buyers who can live with thin published specs.
Verdict
Aquasure is the low-price option among online metered softeners. The Harmony series covers small to very large homes, and the fine-mesh resin versions carry a higher stated iron rating than many softeners. What holds it back is how little the product pages publish: no flow rate, no certification, no valve brand and no base warranty term. If you are buying mainly on price, it is worth a look; if you want documented specs, our ranked picks publish more.
Is Aquasure a fit?
Likely yes
Budget-minded buyers, homes that need a 72,000-grain size at a low price, and well owners with moderate clear-water iron who choose a fine-mesh model.
Likely no
Large homes where flow rate matters and buyers who want a published certification or a clearly stated warranty term.
Specifications
Sizing guidance and prices below are Aquasure's own, read in October 2026.
| Model | Capacity | Maker's sizing | Price (Oct 2026) |
|---|---|---|---|
| Harmony AS-HS32D | 32,000 grains | 1–2 bathrooms, up to 3 people | $539.99 |
| Harmony AS-HS48D | 48,000 grains | 4–5 bathrooms, up to 5–6 people | $629.99 |
| Harmony AS-HS48FM (fine mesh) | 48,000 grains | As 48K; iron up to 10 ppm | $699.99 |
| Harmony AS-HS64D | 64,000 grains | 6+ bathrooms, up to 5–7 people | $749.99 |
| Harmony AS-HS72D | 72,000 grains | 6+ bathrooms, 7+ people | $799.99 |
| Harmony Lite AS-HL34 | 34,000 grains (cabinet) | 1–3 bathrooms, up to 4 people | $489.99 standard, $569.99 fine mesh |
Every Harmony model uses what Aquasure calls an "automatic digital metered control head"; the valve brand is not published. Flow rate is not published, because the specifications tab carried no text when the page was read. Standard-resin models are stated to remove up to 2 ppm iron and fine-mesh models up to 10 ppm. The 48K comes in either 3/4-inch or 1-inch NPT for the same price.
What it does well
Low entry price. At $539.99 for 32,000 grains, the HS32D is the lowest-priced metered softener among the online brands we cover. Even the 72,000-grain HS72D is under $800.
Fine-mesh resin for iron. Aquasure rates its fine-mesh versions for up to 10 ppm of iron. That is a higher stated figure than many softeners publish. As with any softener, the rating applies to dissolved clear-water iron; red-water iron, iron bacteria and hydrogen sulfide still call for a dedicated filter.
Wide size range. Four tank sizes plus a cabinet model make it easy to size by grains rather than settling for the nearest available unit. Aquasure also claims a resin lifespan of 10 years or more.
Bundles for whole-home treatment. The Signature Elite AS-SE1500A packages the 64K Harmony softener with a pleated sediment filter, the Fortitude Pro 1,500,000-gallon treatment system and a 75 GPD reverse osmosis unit for $1,849.99.
Where it falls short
- No published flow rate. For homes with several bathrooms running at once, this is the number that tells you whether pressure will hold. Aquasure's pages do not give it.
- No published certification. None of the Harmony product pages states an NSF, WQA or IAPMO certification.
- Base warranty term not published. The site footer offers a "2-year extended warranty for all Aquasure registered products" and says an extended warranty is available within 60 days of purchase, but the standard term is not stated.
- Valve maker unnamed. That makes it harder to judge long-term parts availability.
- Bundle warranty and certification not published for the Signature Elite.
This review sticks to Aquasure's published specifications and warranty terms.
Pros and cons
Pros
Lowest prices among the online metered softeners we cover, sizes up to 72,000 grains, fine-mesh options rated to 10 ppm iron, and a whole-home bundle with RO.
Cons
No published flow rate, certification, valve brand or base warranty term.
Price and warranty
As of October 2026, Aquasure lists the Harmony HS32D at $539.99, HS48D at $629.99, HS64D at $749.99 and HS72D at $799.99. The fine-mesh HS48FM is $699.99. The Harmony Lite cabinet softener is $489.99 with standard resin or $569.99 with fine-mesh resin. The Signature Elite bundle is $1,849.99.
On warranty, the published wording is limited to the footer: a 2-year extended warranty for registered products, with extended coverage available on purchases within 60 days. Ask for the full warranty document before buying so you know the base term on the tank, resin and control head.
How it compares with our picks
Aquasure wins on sticker price. The lowest-priced SoftPro softener, the ECO, starts at $947 (well) or $967 (city) for 32,000 grains as of October 2026, against $539.99 for the Harmony 32K. What the extra money buys is published detail: the ECO City lists 8% crosslink resin, lifetime limited cover for its mineral and brine tanks, a decade on the valve, and a 6-month money-back guarantee. The ECO Well also uses fine-mesh resin and carries SoftPro's "Lifetime Limited Warranty." See the SoftPro ECO review.
QWT's Fleck 5600SXT (24,000 grains for $1,189) uses a named Fleck (Pentair) valve with a 5-year valve and 10-year tank warranty, which matters if you want parts any installer can source. Read the Fleck 5600SXT review and our Fleck vs GE comparison.
For iron, the Fleck 2510SXT basic package is stated for up to 3 ppm clear-water iron, lower than Aquasure's 10 ppm fine-mesh figure, but QWT and SoftPro both offer iron filter bundles for higher levels; SoftPro lists 30 ppm for its AIO Iron Master.
