$629.99 price checked August 2026
If you need to remove sediment and organic chemicals from your water, this system is the right choice.
What the Aquasure Harmony Series Is, and Who For
The Aquasure Harmony Series 72,000 Grains Water Softener is for large estates requiring high-capacity treatment because it is rated to treat 30,000 grains of water hardness.
Hard water minerals like calcium and magnesium cause significant irritation to the skin and hair while leaving deposits on household fixtures. These minerals can also lead to scale buildup that restricts the lifespan of water-using appliances like dishwashers and washing machines.
The Aquasure Harmony Series 72,000 Grains Water Softener addresses these issues by providing a 30,000-grain capacity for whole-house treatment. It includes a Triple Purpose Sediment/GAC/Zinc Pre-treatment filter that removes up to 99% of contaminants, including rust, silt, and chlorine.

The Short Answer on the Aquasure Harmony Series
Best for: you need a system capable of treating water for a 4-6 bathroom home while removing specific contaminants like chlorine and VOCs.
The Aquasure Harmony Series is a strong choice at the $629.99 price point.
- Pro: The 30,000 grain capacity is sufficient for large household demands.
- Pro: It includes a Triple Purpose Sediment/GAC/Zinc Pre-treatment filter to remove 99% of contaminants like rust and pharmaceuticals.
- Pro: The programmable backlit digital display allows for customized auto-flush intervals based on your specific water usage.
- Con: The 30,000 grain capacity falls short of the 72,000 grain threshold required for high-flow irrigation or very large estates.
- Con: The 4.4 rating from 127 buyers is lower than some high-volume industry standards, suggesting potential variability in user experiences.
Don’t buy this if: your property requires a capacity of 72,000 grains to prevent frequent regeneration cycles.
Price assessment: The $629.99 price is fair for a system that includes both a 30,000-grain softener and a multi-stage pre-treatment filter.

Before You Buy: Aquasure Harmony Series Checklist
The first thing to check is whether your home’s water hardness and usage volume align with the 30,000 grain capacity of the Aquasure Harmony Series.
- ✅ Confirm your water hardness requirements—30,000 grains is the capacity for this unit.
- ✅ Verify your plumbing layout—the system requires a dedicated space for the tank and pre-treatment filter.
- ✅ Check your water source—ensure your supply contains the minerals this system is designed to remove.
- ✅ Budget for professional installation—hire a qualified plumber to handle the plumbing and connection to local codes.
- ✅ Measure your available space—ensure there is room for the Triple Purpose Sediment/GAC/Zinc Pre-treatment filter.
You should not buy this product if your household requires a capacity above 30,000 grains, such as a large estate requiring the 72,000 grain threshold.
Performance in Practical Terms
Triple Purpose Pre-treatment Filtration
The Triple Purpose Sediment/GAC/Zinc Pre-treatment filter removes up to 99% of contaminants, including chlorine, VOCs, and pharmaceuticals. This filtration allows you to remove the chemical smell and “chemical” feel of your water before it reaches the softening stage.
Because the system addresses sediment, rust, and silt alongside organic chemicals, you can expect cleaner water flow into your plumbing. If your local water profile contains specific industrial contaminants not listed in these specifications, you should confirm your local water quality report before installation.
Digital Metered Control Valve
The Aquasure Harmony Series features a programmable backlit digital display to manage auto-flush intervals based on your specific water usage. This digital control allows you to customize the regeneration cycle to match your household’s consumption patterns.
By adjusting the settings to your local water quality, you can ensure the system operates efficiently without unnecessary cycles. You should verify your local water hardness levels to determine the most effective programming for your specific area.
Mineral Removal for Skin and Hair
The Aquasure Harmony Series is rated to treat 30,000 grains of water hardness, which targets the calcium and magnesium that cause dry hair and skin irritation. This capacity allows you to effectively soften water for 4-6+ bathrooms.
While 30,000 grains covers many standard households, you should confirm your local water hardness if you have a high-flow irrigation requirement or a large estate, as those may require a higher capacity threshold. This 30,000-grain rating ensures the removal of minerals that typically cause scale buildup on fixtures and appliances.
How the Aquasure Harmony Series Compares to Alternatives
The Aquasure Harmony Series offers a 30,000 grain capacity, which sits exactly at the 32,000 grain threshold required to service a standard 3-bedroom household with moderate hardness.

Is the Aquasure Harmony Series Right for You?
The Aquasure Harmony Series suits 5 kinds of buyer and is the wrong choice for 3 jobs, listed below with the reason for each.
Who the Aquasure Harmony Series is for, and what it does well
Who the Aquasure Harmony Series suits
- Large families with 4-6 bathrooms — the 30,000 grain capacity is specifically designed to handle the high volume of water usage in large households
- Skincare enthusiasts with sensitive skin — the removal of calcium and magnesium prevents skin pore clogging and irritation
- Homeowners with high-sediment well water — the Triple Purpose Sediment/GAC/Zinc Pre-treatment filter removes 99% of contaminants like rust and silt
- Property managers of multi-unit buildings — the programmable digital metered control valve allows for easy monitoring and customized auto-flush intervals
- People with chronic dry hair — the mineral removal process specifically targets the minerals that cause hair to become dry and brittle
What the Aquasure Harmony Series handles well
- Running high-efficiency washing machines — the scale elimination protects plumbing and prolongs the lifespan of water-using appliances
- Maintaining water heaters — the removal of hard minerals prevents scale buildup inside the heating elements
- Managing high-turbidity water sources — the pre-treatment filter removes turbidity and organic chemicals
- Customizing water treatment for variable usage — the backlit digital display allows for easy customization of auto-flush intervals
- Removing chlorine from tap water — the GAC filter in the pre-treatment system handles chlorine and VOCs
What the Aquasure Harmony Series is the wrong choice for
- Industrial manufacturing plants — the 30,000 grain capacity is rated for residential use rather than heavy industrial volume
- Commercial laundromats — the residential-grade design cannot handle the extreme high-volume flow of a commercial laundry
- Ultra-large estates with 10+ bathrooms — the 30,000 grain limit may be insufficient for extremely large-scale plumbing systems
What to budget alongside the Aquasure Harmony Series, and what to skip
Worth buying at the same time
- Water testing kit — needed to determine the incoming water quality to properly program the digital metered control valve
- Plumbing installation hardware — required to connect the unit to the home’s main water line and the pre-treatment filter
- Replacement filter cartridges — needed to maintain the Triple Purpose Sediment/GAC/Zinc Pre-treatment system over time
- Drainage piping — required to facilitate the auto-flush intervals managed by the digital control valve
- Pressure gauge — needed to monitor the flow and pressure before and after the pre-treatment filtration stage
What you can skip
- Separate sediment filter — the unit already includes a Triple Purpose Sediment/GAC/Zinc Pre-treatment filter
- Manual bypass valve — the automatic digital metered control valve handles the necessary flow management and monitoring
- Basic chlorine tablets — the GAC filter in the pre-treatment system already removes chlorine and VOCs
