Options include black and white finishes, with digital metered controls standard across the range. Some bundles add sediment filtration or reverse osmosis systems.

How to choose the right one
-
Match capacity to bathrooms
Select your grain capacity based on the number of bathrooms you need to protect. The Harmony 48,000 Grain Softener is designed for homes with three to four bathrooms. If you have a larger household with six or more bathrooms, the 72,000 Grain Bundle provides the necessary robust capacity. Smaller homes with one to three bathrooms can use the Harmony Lite 34k Grain White Softener. Choosing the correct capacity ensures effective scale protection without wasting salt or energy on an oversized unit.
-
Check digital control type
All listed models feature digital metered controls. This technology adjusts regeneration cycles based on actual water usage rather than a fixed timer. You get more efficient operation and consistent water quality. The control panels are integrated into the whole-house installation. This means you do not need separate manual valves for operation. The digital interface handles the scheduling automatically. You benefit from precise management of the softening process. This standard feature is present across the entire Aquasure lineup in this guide.
-
Verify pre-filtration needs
Some bundles include sediment filters to protect the resin bed. The Harmony 72,000 Grain Bundle and the Harmony Lite 34k Grain White Softener both feature sediment filters. These filters remove larger particles before water reaches the softener. This extends the life of the resin and maintains flow rates. If your water has high sediment levels, prioritize models with this feature. The Harmony 48,000 Grain Softener does not list this inclusion. You may need to add a separate pre-filter if you choose that model.
-
Consider RO bundle options
If you want purified drinking water alongside softening, look for the bundle with the 75 GPD RO system. The Aquasure 72k Grain Bundle w/ 75 GPD RO combines whole-house softening with a reverse osmosis unit. This setup suits families needing both soft water for appliances and clean water for drinking. It fits homes with up to six bathrooms. This all-in-one package simplifies maintenance by handling both water treatment types in a coordinated system.
-
Assess physical dimensions
Check the height and width to ensure the unit fits your installation space. The Harmony 48k Grain model is 62 inches tall and 10 inches wide. The Harmony Lite 34k Grain White Softener is shorter at 43 inches tall but wider at 18.5 inches. The 72,000 Grain Bundle is 60 inches tall and 12 inches wide. Measure your utility area carefully before purchasing. The weight also varies, with the 48k model weighing 120 pounds. Ensure your floor can support the installed weight.
