PurASoft® ECR 3702 R50S Water Softener
The PurASoft® ECR 3702 R50S Water Softener is a high-efficiency whole-home water softening system designed to protect your home from the damaging effects of hard water while delivering cleaner, softer water throughout every faucet and appliance. Built on proven EcoWater technology, the ECR 3702 R50S combines reliable performance, smart regeneration technology, and efficient operation to help homeowners solve some of the most common water quality problems found in municipal and well water supplies.

Hard water affects much more than the appearance of your faucets and shower doors. Over time, calcium and magnesium minerals accumulate inside plumbing systems, water heaters, dishwashers, washing machines, and other water-using appliances. This mineral buildup can reduce efficiency, increase maintenance costs, shorten equipment lifespan, and make everyday cleaning more difficult.
The PurASoft® ECR 3702 R50S is engineered to remove hardness minerals before they have the opportunity to damage your home. By supplying softened water throughout your plumbing system, the ECR 3702 R50S helps reduce scale buildup, improve appliance efficiency, and create a more comfortable everyday water experience.
Many homeowners choose the PurASoft® ECR 3702 R50S to address common hard water issues such as:
- White scale buildup on fixtures and glass surfaces
- Soap scum in showers and sinks
- Dry skin and dull hair after bathing
- Spotted dishes and cloudy glassware
- Stiff or faded laundry
- Reduced water heater performance
- Frequent appliance repairs caused by mineral buildup
The PurASoft® ECR 3702 R50S is an excellent solution for medium to large households looking for dependable water softening without stepping into the larger capacities designed for very high water demand applications. Its efficient design provides plenty of soft water for daily household use while helping minimize salt and water consumption.
At the heart of the system is intelligent demand regeneration technology that continuously monitors your home’s actual water usage. Instead of regenerating on a fixed schedule, the PurASoft® ECR 3702 R50S regenerates only when necessary. This helps conserve salt, reduce water waste, and lower operating costs while maintaining a consistent supply of soft water.
The system is designed to provide reliable performance for busy households where multiple fixtures and appliances may be used throughout the day. Whether you’re running showers, laundry, dishwashers, or irrigation systems, the PurASoft® ECR 3702 R50S helps maintain dependable water quality while protecting your plumbing infrastructure from the long-term effects of hard water.
Homeowners often report noticeable improvements shortly after installation, including:
- Softer skin and hair
- Cleaner dishes and glassware
- Brighter, softer clothing and linens
- Reduced cleaning time in kitchens and bathrooms
- Improved appliance efficiency
- Less scale buildup on plumbing fixtures
- Longer lifespan for water heaters and household appliances
