PurASoft® ECR 3702 R70 Water Softener

The PurASoft® ECR 3702 R70 Water Softener is one of Angel Water’s most powerful whole-home softening systems, designed for homes battling severe hard water buildup, heavy water usage, and long-term appliance wear caused by mineral-rich water. Built on advanced EcoWater technology, the ECR 3702 R70 delivers high-capacity performance, intelligent efficiency, and reliable protection for larger homes and demanding water conditions.

Hard water can quietly damage nearly every plumbing fixture and water-using appliance in your home. Over time, calcium and magnesium minerals accumulate inside pipes, water heaters, dishwashers, faucets, and showerheads, creating scale buildup that reduces efficiency and shortens equipment lifespan. Hard water can also leave skin feeling dry, hair feeling brittle, laundry looking dull, and dishes covered in stubborn spots and residue.

The PurASoft® ECR 3702 R70 is engineered to solve these problems by removing hardness minerals before they circulate throughout your plumbing system. By delivering softened water to every faucet and appliance, the system helps protect your home while dramatically improving the everyday feel and performance of your water.

With its high-capacity 70,000-grain design, the PurASoft® ECR 3702 R70 is an excellent fit for:

• Large households with high daily water usage
• Homes with multiple bathrooms
• Properties with extremely hard water conditions
• Families using oversized tubs, body sprays, or rainfall shower systems
• Homeowners looking to maximize appliance protection and efficiency

The PurASoft® ECR 3702 R70 features advanced demand-based regeneration technology that monitors your household’s actual water usage and regenerates only when necessary. This intelligent operation helps reduce unnecessary salt consumption and water waste while ensuring your home continues receiving softened water when you need it most.

Unlike older timer-based systems that regenerate on fixed schedules regardless of usage, the ECR 3702 R70 adapts to your family’s water habits to improve overall efficiency and long-term operating costs.

Homeowners commonly notice major improvements after installing a PurASoft® Water Softener, including:

• Less scale buildup on faucets, fixtures, and shower doors
• Softer skin and smoother hair after bathing
• Cleaner dishes and spot-free glassware
• Brighter, softer laundry
• Improved soap and detergent performance
• Longer appliance lifespan
• Better water heater efficiency
• Reduced cleaning time throughout the home

The PurASoft® ECR 3702 R70 is also designed to maintain strong household flow rates, making it ideal for homes where multiple showers, appliances, and fixtures may be running simultaneously.
