A 64,000-grain whole house water softener for four or more bathrooms, with a digital metered head.
The cheapest grains on this shelf, and the end of Aquasure’s own ladder:
32,000 — $523.29 — $16.35 per thousand 48,000 — $629.99 — $13.12 50,000 — $679.99 — $13.60 64,000 — $749.99 — $11.72
Twice the capacity of the entry model for $226.70.
This is the part the listings never explain.
The cost of a regeneration is mostly fixed. Each cycle pushes a set quantity of brine through the resin and rinses it out, spending salt and perhaps fifty gallons of water whether the bed was nearly spent or only half used.
A larger bed therefore regenerates less often for the same household, and removes more grains for the same salt each time it does.
The trade industry sizes a softener to regenerate roughly weekly. Sizing down to save money at purchase usually costs more across ten years of salt.
Sixty-seven and a half kilograms. Three hundred and eighty-one millimeters square. One thousand five hundred and twenty-four millimeters tall.
Fifteen inches square and five feet high, and the heaviest of the four Aquasures here — only the 222 lb (100.7 kg) PRO+AQUA on this shelf is heavier. Two people and a clear route to the basement, and headroom above it to lift the control head for service.
Aquasure’s 32,000-grain model is 7.99 in (203 mm) square and thirty kilograms. If the space is a cabinet, that is the one that goes in.
Not in a large house. In a small one.
The sizing arithmetic cuts both ways: hardness in grains per gallon times daily gallons gives grains per day, and you want about a week between regenerations. Two people on 15 gpg water using 120 gallons a day consume 1,800 grains daily — which this unit would stretch to five weeks, and resin left standing that long does not stay in good condition.
For that house, the 32,000-grain Aquasure or the 40,000-grain Aquasana is the right machine.
No pre-filter. On a well, that is fine. On chlorinated municipal water, chlorine oxidizes the resin and shortens its life — which is exactly why Aquasure’s 48,000 and 50,000 grain models include a carbon stage and AFWFilters uses 10% crosslink resin.
If this is going on city water, buy a carbon pre-filter with it.
No certification, no resin volume, no flow rate.

Because the cost of a regeneration is largely fixed. Each cycle flushes a set quantity of brine through the bed and then rinses it, spending salt and perhaps fifty gallons of water regardless of how many grains were actually removed. A bigger bed holds more capacity, so it regenerates less often for the same household, and each regeneration removes more grains for the same salt. The industry rule of thumb is to size a softener so it regenerates about once a week, not daily — which is also why sizing down to save money usually costs more over ten years.
It can be, and the reason is counter-intuitive: resin that sits unregenerated for too long can foul, and some softeners are set to regenerate at least every so often regardless. The real answer is the arithmetic — hardness in grains per gallon multiplied by daily gallons gives grains per day, and you want roughly a week between regenerations. On 15 gpg water a two-person household using 120 gallons a day consumes 1,800 grains daily, which a 64,000-grain unit would stretch to five weeks. That is too long, and the 32,000 or the 40,000-grain Aquasana would suit better.
On well water, not much. On chlorinated city water, a good deal: chlorine oxidizes softener resin and shortens its life. Aquasure’s 48,000 and 50,000 grain models on this shelf include a sediment, carbon and zinc pre-filter; this one does not. AFWFilters tackles the same problem with 10% crosslink resin. If this softener is going on municipal water, budget for a carbon pre-filter ahead of it.
Same category, nearby prices, between bathroom fittings. What remains is the specifications every one publishes — half empty, a column is no use.
