WaterBoss is documented here through the Model 900, using facts from WaterBoss's own product page. The Model 900 is positioned as a compact all-in-one that combines softening, iron reduction, and sediment filtration in a single cabinet, so the cited evidence centers on those combined functions and on an unusually short, low-salt regeneration cycle. Read the iron figure as a clear-water, or ferrous, iron rating, which is the dissolved form a softener can address.
Capacity and combined filtration
The Model 900 pairs softening with built-in filtration in one unit. WaterBoss's page lists a 38,000 grain capacity for a household of six or more, and describes a built-in self-cleaning filter that removes water stains, spots, calcium, ferrous iron, dirt, and sediment. Integrating the filter means the owner does not run a separate sediment cartridge ahead of the softener for the particulates the built-in filter handles.
That all-in-one design is the Model 900's core proposition: rather than assembling a softener, an iron filter, and a sediment filter as separate tanks, the buyer gets the combined function in a single compact cabinet. A buyer with heavy sediment or high iron should still confirm the built-in filter meets their raw-water load.
Iron reduction
The Model 900 targets the dissolved iron common in well water. WaterBoss states the unit removes up to 10 ppm of clear water iron. Clear-water, or ferrous, iron is the dissolved form that stays invisible until it oxidizes and stains fixtures; a softener's ion-exchange resin can capture it along with hardness up to a limit.
The 10 ppm figure is a meaningful ceiling for well-water buyers, since iron above a softener's rating fouls the resin and calls for a dedicated oxidizing iron filter instead. A buyer should test raw iron and confirm whether it is present as clear-water iron before relying on a softener to handle it, because oxidized red-water iron behaves differently.
Fast, low-salt regeneration
The Model 900's most distinctive claim is the speed and economy of its regeneration cycle. WaterBoss states the unit regenerates in just 25 minutes, using only 1 pound of salt and 20 gallons of water per cycle. A conventional softener can take 60 to 120 minutes to regenerate, so a 25-minute cycle shortens the window during which the unit is off-line.
The low salt and water use per cycle is part of WaterBoss's efficiency argument, though total consumption depends on how often the unit regenerates, which is driven by household hardness and demand. A buyer comparing running costs should look at salt and water use over a month of typical use, not just the per-cycle figures.
Unresolved unknowns
The cited WaterBoss product page states capacity, iron reduction, and regeneration figures, but does not state a maximum hardness grains-per-gallon rating for the Model 900 in the content reviewed, so a buyer with very hard water should confirm the ceiling. The page also does not confirm an NSF/ANSI 44 certification in the cited content.
Service flow rate, dimensions, and warranty term are not stated on the cited page. Confirm the flow rate against peak household demand, the physical footprint, and the warranty length before purchase, and verify whether the built-in filter suffices for the household's sediment and iron load.
