PurASoft® ECR 3700 R30 Water Softener
The PurASoft® ECR 3700 R30 Water Softener is an efficient whole-home water softening system designed to eliminate the everyday problems caused by hard water while helping protect your plumbing, appliances, and fixtures for years to come. Built on trusted EcoWater technology and professionally installed by Angel Water, the ECR 3700 R30 delivers dependable performance, intelligent water management, and lasting value for homeowners looking to enjoy cleaner, softer water throughout their home.

Hard water doesn’t just leave behind spots on dishes—it gradually affects nearly every water-using appliance in your home. Calcium and magnesium minerals accumulate inside water heaters, washing machines, dishwashers, plumbing pipes, and faucets, creating scale buildup that reduces efficiency, increases energy costs, and shortens the lifespan of expensive equipment.
The PurASoft® ECR 3700 R30 is engineered to remove these hardness minerals before they can cause damage. By delivering softened water to every faucet, shower, and appliance, the system helps improve cleaning performance, reduce scale buildup, and make everyday water noticeably more comfortable.
Homeowners often install the PurASoft® ECR 3700 R30 to solve problems such as:
- White scale buildup on faucets and fixtures
- Soap scum in showers and bathtubs
- Dry skin and rough-feeling hair after bathing
- Water spots on dishes and glassware
- Stiff towels and faded laundry
- Reduced water heater efficiency
- Frequent appliance maintenance caused by mineral buildup
The PurASoft® ECR 3700 R30 is an excellent choice for smaller homes, townhomes, condominiums, and families with moderate water usage. It delivers the benefits of premium whole-home water softening while providing an efficient solution that doesn’t exceed the needs of the average household.
Using intelligent demand regeneration technology, the PurASoft® ECR 3700 R30 continuously monitors your household’s water consumption and regenerates only when necessary. Unlike older timer-based softeners that regenerate whether they’re needed or not, this smart system helps conserve both salt and water while ensuring your family always has a reliable supply of softened water.
By adapting to your home’s actual water usage patterns, the system provides dependable performance while helping keep long-term operating costs low.
After installing a PurASoft® Water Softener, many homeowners notice immediate improvements throughout their home, including:
- Softer skin and healthier-looking hair
- Cleaner dishes with fewer water spots
- Brighter, softer clothing and towels
- Less scale buildup on fixtures and shower doors
- Improved soap and detergent performance
- Easier household cleaning
- Longer-lasting plumbing fixtures and appliances
At Angel Water, every PurASoft® Water Softener recommendation begins with professional water testing and a personalized evaluation of your home’s water conditions. Our water quality specialists assess hardness levels, household size, plumbing configuration, and daily water usage to ensure your system is properly sized for maximum efficiency and long-term performance.
If you’re looking for an affordable, dependable whole-home water softening solution, the PurASoft® ECR 3700 R30 Water Softener offers an excellent combination of performance, efficiency, and value. It’s an ideal choice for homeowners who want to protect their home from hard water while enjoying softer, cleaner water every day.
