01 Aquasure 72k Bundle Comparison

Included Filtration

Edge: Aquasure 72k Grain Bundle w/ 75 GPD RO

The Aquasure Harmony 72,000 Grain Bundle focuses on whole-house softening and pre-filtration. It includes a triple-purpose sediment, GAC, and zinc pre-filter to remove contaminants before the water reaches your softener. This model does not list an under-sink reverse osmosis system in its specifications. In contrast, the Aquasure 72k Grain Bundle w/ 75 GPD RO adds a dedicated 4-stage reverse osmosis system. This RO unit provides additional filtration for drinking water, ensuring cleaner and better-tasting water at your kitchen faucet. If you want purified drinking water without buying a separate unit, this bundle includes it.

Physical Footprint

Edge: Aquasure 72k Grain Bundle w/ 75 GPD RO

Space planning matters for utility rooms and garages. The Aquasure Harmony 72,000 Grain Bundle measures 12 inches wide, 12 inches long, and 60 inches high. Its cylindrical tank requires a wider diameter footprint. The Aquasure 72k Grain Bundle w/ 75 GPD RO has a different configuration. Its primary unit measures 10 inches wide, 10 inches long, and 56 inches high. This model is slightly shorter and narrower. Both systems are whole-house installations, but the Harmony bundle is taller. The 72k bundle with RO is more compact in width and height, which may fit tighter spaces better.

Tank Construction

Edge: Aquasure 72k Grain Bundle w/ 75 GPD RO

Durability depends on how the tank is built. The Aquasure Harmony 72,000 Grain Bundle specifies a high-strength, corrosion-resistant stainless steel bypass valve. It also uses prefilled premium-grade resin. The exact tank material is not explicitly detailed in the provided specs, though it is implied to be durable. The Aquasure 72k Grain Bundle w/ 75 GPD RO explicitly states its tank is constructed with fiberglass-lined polyethylene. This material is known for resisting corrosion and scaling. Both use premium-grade resin and automatic digital metered control valves. The explicit mention of fiberglass lining in the second model offers clarity on its internal protection against rust.

Grain Capacity

Edge: Tie

Both systems share the same core softening capability. The Aquasure Harmony 72,000 Grain Bundle is rated to treat 72,000 grains of hardness. The Aquasure 72k Grain Bundle w/ 75 GPD RO is also rated to treat 72,000 grains of hardness. Both are designed for whole-house installation and can handle homes with up to six bathrooms. The softening performance is identical for the main water supply. You get the same amount of softened water from both units before they require regeneration. This aspect is a complete tie, as neither model offers more grain capacity than the other.

Control Valve

Edge: Tie

Both models feature an automatic digital metered control valve. This valve allows you to customize auto-flush intervals based on your water quality and usage. It includes a fully programmable backlit digital display for easy monitoring and maintenance. Neither system requires manual regeneration, backwashing, or draining. The technology is the same in both bundles, providing hassle-free operation. You get the same level of automation and control regardless of which bundle you choose. This feature is identical in function and specification for both products.
