It treats limescale. It is not a health device. · review
An 80,000-grain softener combined with a three-stage whole house filter, rated up to 20 GPM.
That figure appears on one listing out of twelve, and it is arguably the most important number on this shelf.
Every drop of water in the house passes through the softener. If the softener cannot pass enough, it becomes the bottleneck in the plumbing — and the symptom is a shower that weakens when the washing machine fills.
Two showers and a dishwasher together can want 10 to 12 gallons a minute. A large house with a bath running as well wants more.
Eleven listings here publish no flow rate at all. The closest anybody comes is Kenmore naming a 3/4 inch valve and GE naming 1 inch connections — useful hints, not numbers.
Grain capacity tells you how long between regenerations. Flow rate tells you whether the house works.
The largest softener capacity on this shelf, paired with three stages of whole-house filtration for chlorine, iron, VOCs, rust and sediment.
And a benefit the page does not spell out: removing chlorine before the resin protects the resin. Chlorine oxidizes softener beads and shortens their life, which is why a softener on municipal water wears out faster than the same softener on a well.
Four listings on this shelf address chlorine at all — this one, Aquasure’s two models with carbon pre-filters, and AFWFilters with its 10% crosslink resin.
Which is the middle of this shelf on October 29, 2026. Aquasure’s 64,000-grain unit is $11.72; the Kenmore is $20.51.
That is reasonable for 80,000 grains with three filtration stages, a 5-year softener warranty and lifetime support attached.
100,697 grams. The heaviest item on this shelf by thirty-three kilograms.
Nine hundred and fourteen millimeters. The shortest system here, where Aquasure’s 48,000-grain tower stands 62 in (1,575 mm).
Short and heavy is easier through a basement door than tall and heavy — but this is a two-person installation with a cart, and the house plumbing has to be sized for 20 GPM for the flow rating to mean anything.
No certification. Neither IAPMO to NSF/ANSI 44, which both Aquasanas publish, nor any third-party test figure.
No resin volume, no crosslink percentage, no salt capacity, no salt-saving figure.
For a system at this price, the page is confident and thin. The 20 GPM is the one number on it that nobody else gives, and it is a good one.
Available at around $1,156.45 on Amazon.com when we checked on October 29, 2026, for delivery to a US address.

| Resin volume | NOT PUBLISHED — the resin and the tanks are called commercial grade, which is a word and not a volume. |
|---|---|
| Stated capacity between regenerations | 80,000 grains — the largest on this shelf — at $14.46 per 1,000 grains, sized for 6 or more bathrooms on well or municipal water. |
| Regeneration type | A digital metered valve, stated efficient in salt and water usage. |
| Connection size | NOT PUBLISHED. What IS published is a flow rate of up to 20 GPM — THE ONLY FLOW RATE ON THIS SHELF, and the figure that says whether a shower still runs while it works. |
| Stated salt consumption | NOT PUBLISHED as a figure. |
| Footprint | 17 × 17 in (432 × 432 mm) of floor, 36 in (914 mm) tall — the shortest system on this shelf — 222.0 lb (100,697 g), the heaviest here by 72.8 lb (33 kg). It carries the three-stage PRO-100-E whole house filter, treating hardness, chlorine, iron, VOCs, rust and sediment, with easy-access filter housings. Assembled in California. No certification is published. Warranty 5 years on the softener, with lifetime technical support. |

Because every drop of water in the house passes through the softener, and a softener that cannot pass enough water becomes the bottleneck in the plumbing. Two showers and a dishwasher together can want 10 to 12 gallons a minute; a large house with a bath filling as well, more. PRO+AQUA publishes up to 20 GPM. Eleven listings here publish none — the closest anyone else comes is Kenmore naming a 3/4 inch valve and GE naming 1 inch connections. Grain capacity tells you how long between regenerations; flow rate tells you whether the shower goes weak when the washing machine fills.
Different contaminants. Ion exchange removes calcium and magnesium and nothing else; the filtration stages handle chlorine, iron, VOCs, rust and sediment. There is a second benefit the listing does not spell out: removing chlorine before the resin protects the resin, because chlorine oxidizes softener beads and shortens their life. That is the same reasoning behind Aquasure’s carbon pre-filters and AFWFilters’ 10% crosslink resin — four of the twelve listings here address chlorine at all.
Not alone. A hundred point seven kilograms is the heaviest item on this shelf by thirty-three kilos, and it arrives as tanks to be positioned, plumbed and filled. The one mercy is the height: 36 in (914 mm), the shortest system here, where Aquasure’s 48,000-grain tower is 62 in (1575 mm). Short and heavy is easier to get through a basement door than tall and heavy, but this is a two-person job with a cart, and the plumbing should be sized for 20 GPM to be worth having.
Same category, nearby prices, between bathroom fittings. What remains is the specifications every one publishes — half empty, a column is no use.
