PurASure® ERR 3700 R20 Water Refiner

The PurASure® ERR 3700 R20 Water Refiner is a compact whole-home water treatment system that combines high-efficiency water softening with chlorine taste and odor reduction in a single, space-saving unit. Built on advanced EcoWater technology and professionally installed by Angel Water, the ERR 3700 R20 is designed for homeowners who want the benefits of softer, cleaner water without installing separate treatment systems.

Municipal water often contains two common concerns: hard water minerals and chlorine. Hard water can leave scale buildup throughout your plumbing system while chlorine may affect the taste, smell, and overall comfort of your home’s water. The PurASure® ERR 3700 R20 addresses both issues simultaneously, helping improve the quality of the water you use every day for bathing, cooking, cleaning, and drinking.

As water enters your home, the PurASure® ERR 3700 R20 removes hardness minerals such as calcium and magnesium while integrated carbon media reduces chlorine taste and odor. This dual-treatment approach helps protect your plumbing and appliances while creating a noticeably more comfortable water experience throughout the home.

Homeowners frequently choose the PurASure® ERR 3700 R20 to solve common municipal water problems, including:

• Hard water scale on faucets and plumbing fixtures
• Chlorine taste or odor in tap water
• Dry skin and brittle hair after showering
• Soap scum on tubs, showers, and sinks
• Water spots on dishes and glassware
• Mineral buildup inside water heaters and appliances
• Excessive soap and detergent usage

The PurASure® ERR 3700 R20 is an excellent solution for condominiums, townhomes, smaller homes, and households with moderate daily water usage. Its compact design delivers comprehensive whole-home water treatment while fitting comfortably into homes where installation space may be limited.

The system uses intelligent demand regeneration technology that continuously monitors your family’s actual water usage and regenerates only when necessary. Unlike older timer-based systems that regenerate on a fixed schedule, the PurASure® ERR 3700 R20 adapts to your household’s water consumption, helping reduce salt usage, conserve water, and lower long-term operating costs.

Homeowners often notice significant improvements shortly after installation, including:

• Softer skin and healthier-feeling hair
• Cleaner, fresher-tasting water throughout the home
• Reduced chlorine odor during showers
• Brighter laundry and softer towels
• Cleaner dishes with fewer water spots
• Less scale buildup on plumbing fixtures
• Improved efficiency and longer life for water-using appliances

At Angel Water, every PurASure® Water Refiner recommendation begins with professional water testing. Our water quality specialists evaluate your home’s hardness levels, chlorine content, household size, plumbing configuration, and daily water usage to ensure the system is properly sized for your specific needs.

It’s an ideal choice for homeowners who want cleaner, softer water and long-term protection for their plumbing and appliances in one compact, professionally installed system.
