Aqua Science ASWS89 is one of Aqua Science’s premier high-flow, high-efficiency water softener systems, and many customers choose it for large homes and small businesses. It uses ion exchange technology to remove hardness minerals such as calcium and magnesium, while supporting consistent water flow through the unit for better overall water quality.
Hard water affects about 85% of U.S. homes.
Properly sized softeners are crucial for large households, families, small business owners, and high-usage users.
Issues addressed include spotting, soap waste, dry skin, and premature appliance wear, helping protect appliances and plumbing from hard water wear.
A free water test kit can help determine the right system and match the proper grain capacity to your household size and hardness level.
Cuts cleaning time on household fixtures and appliances
Improves the effectiveness of soaps and detergents in daily routines
Can extend appliance life by up to 50%
Saves over $400 annually on soaps and detergents (using Culligan water softeners’ benchmark)
Reduces hard-water waste, saving money over time
Can be a smart investment in lower repair, appliance, and operating costs over time
Leaves skin and hair feeling smooth instead of dry
Sized for higher water usage, the ASWS89 is ideal for larger family households or small-business demand. Sizing should match your household size, water hardness level, and the convenience of easier day-to-day ownership, rather than choosing a cheaper unit that cannot keep up with demand.
The softener targets hardness minerals that cause scale, while a separate filter or other treatment systems handle contaminants affecting safety, odor, or taste.
Downflow Regeneration: In a downflow system, the water flow moves from the top of the tank downward during regeneration, and brine flows the same way through the resin bed; the difference is that the cleaning cycle follows that same top-down path, which can leave hard water at the tank's bottom.
Upflow Regeneration: Uses water pressure to push brine from the bottom up through the resin bed to regenerate media more evenly, a practical contrast to downflow systems where the cleaning path starts at the top.
Counter-current regeneration and upflow brining for efficient performance
Uses less salt and water, saving 30–50% compared to traditional downflow regeneration
Produces more even resin-bed regeneration, helping restore the bed more completely while producing more consistent results and protecting long-term system performance
Saves water and salt by regenerating only as needed
Makes the system's performance and water usage easier to monitor
Helps limit unnecessary electricity and operating costs
Regenerates using salt or potassium
The valve and tank design also reduce unnecessary plastic where durability matters most, and the ASWS89 is part of efficient water softener systems designed for low routine maintenance.
Aqua Science, founded in 1985, sells water systems online and specializes in water treatment systems and well water equipment.
This overview focuses on the ASWS89's capacity, efficiency, installation, regeneration options, and benefits, giving larger households and light commercial buyers a clear picture of how it fits their water use, how much water it uses during regeneration, and their hardness levels. It also notes the difference between this unit’s regeneration approach and more basic alternatives, so you can better compare where it fits in complete water treatment systems. Altogether, this helps you understand how it works and choose a tested system that is a smart long-term investment for buyers who want efficiency and protection for plumbing and appliances.
