It includes a high-performance digital metered control head and a triple-purpose pre-filter (sediment, GAC, zinc) to remove chlorine, VOCs, PFAs, and other contaminants, promoting clean water throughout the home. This model aims to protect appliances by reducing scale buildup and extending their lifespans.
Aquasure Harmony Series 40,000 Grains

The Aquasure Harmony Series 40,000 grains model is designed for homes with 3-4 bathrooms. It uses a digital metered control head for efficient regeneration and features a triple-purpose pre-filter to reduce chlorine, odors, and sediment. It helps prevent scale in pipes and appliances while delivering softer water across all taps and fixtures.
64,000 Grain Aquasure Harmony

For larger households, the 64,000-grain Aquasure Harmony model provides robust treatment for 4+ bathrooms. It reduces hardness and mineral buildup while protecting plumbing and appliances from scale. The included pre-filter helps minimize contaminants to maintain water quality and improve overall system efficiency.
Morton Water Softener Salt Crystals

Morton Pure and Natural Water Softener Salt pellets come in a 4-pack of 40 lb bags. This high-purity salt is formulated to optimize water softening systems, reducing dryness and irritation for skin and hair while helping to minimize mineral buildup in pipes and appliances. It’s a practical option for households seeking reliable salt supply for softening units.
2 Pack Water Softener Salt Pellets

Two 40 lb bags (total 80 lb) of water softener salt pellets deliver solid-performing hardness relief and improved water taste. They help reduce rust stains and protect the integrity of plumbing and appliances by minimizing mineral buildup associated with hard water. This option is suitable for households with ongoing softener maintenance needs.
Pro Products Res Care Liquid Water Softener Cleaner

It helps remove contaminants like iron, manganese, silt, and metal particles that can accumulate in resin beds. Regular use can extend resin life and support consistent water quality across the home.
Buying Guide: Key Purchase Considerations
- Household size and water hardness: Larger homes or higher hardness levels require bigger grain capacity (40k–64k+). For 3-6 bathrooms, 40k–50k grains typically balances performance and cost.
- Whole-house vs. point-of-use: Whole-house units treat all water entering the home, improving skin, appliances, and overall water quality. Point-of-use filters target a single faucet or appliance and are not covered here.
- Regeneration method: Time-based vs. metered systems impact efficiency and salt usage. Metered controls are generally more water- and salt-efficient.
- Pre-filters and contaminants: A triple-purpose pre-filter (sediment/GAC/zinc) helps remove chlorine, VOCs, and odors, enhancing water taste and protecting the resin bed.
- Salt type and availability: Salt pellets or crystals should be chosen based on system requirements and local water chemistry. Ensure the salt supply is readily available and affordable.
- Maintenance and lifespan: Regular resin cleaning with cleaners can extend system life. Keep replacement parts and cleaners compatible with your model.
- Appliance protection: Look for systems that explicitly mention protecting appliances like water heaters and dishwashers from scale buildup.
When evaluating options, prioritize models with clear grain capacity, reputable brand support, and features that address your water quality concerns. Salt-based salt crystals are common for households with older systems or those needing a straightforward replenishment routine, while electronic metered units offer advanced efficiency and longer-term savings through reduced salt and water use.
