How to Choose Water Softeners
Understand Grain Capacity
Grain capacity measures how much hardness a water softener can handle. Look for models rated for at least 30,000 grains for average homes. Higher capacity means more efficient softening. For larger households, consider options like 48,000 or 50,000 grains.
Consider the Number of Bathrooms
Choose a water softener based on how many bathrooms you have. For homes with 1-2 bathrooms, models like the Aquasure Harmony Series 32,000 Grains are adequate. For 3-4 bathrooms, look at options like the Aquasure Harmony Series 48,000 Grains to ensure adequate softening.
Look for Efficiency Ratings
Efficient salt usage saves money and reduces waste. Check for options with digital metered control heads, which regenerate only when necessary. This feature minimizes salt usage and extends the lifespan of the unit.
Check for Additional Features
Some water softeners come with extra features like pre-filters or advanced control systems. These can enhance performance and help maintain water quality. Consider what additional features may benefit your household.
Plan for Regular Maintenance
All water softeners need regular maintenance, like salt refills. Choose a model that is easy to maintain and monitor. Look for systems with clear indicators for salt levels.

What to look for
Grain Capacity Matters
Grain capacity is key to choosing a water softener. It tells you how much hardness the unit can treat. For typical households, a capacity of at least 30,000 grains is recommended. Larger families should look for models between 40,000 and 50,000 grains for better performance.

Maintenance Requirements
All water softeners require maintenance to function well. Regularly check salt levels and clean the system as needed. Some models have features to remind you when maintenance is due, making upkeep easier.
Space Considerations
Space can be a factor in choosing a water softener. Make sure to measure the area where it will be installed. Compact models are available for smaller homes, while larger systems may require more room.
