Product details
Improve your home's water quality with the NU Aqua Whole House Salt Free Water Softener With Total Filtration. This powerful 4-stage system not only removes heavy metals, contaminants, and unpleasant odors but also acts as a salt-free water softener—helping to reduce scale buildup and extend the life of your plumbing and appliances. From the kitchen to the shower, enjoy cleaner, softer water throughout your entire home or business.
Performance You Can Count On. Protection You Can Trust.
Whether you're enhancing your home’s water system or equipping a commercial property, this professional-grade solution is built to meet the demands of any space—homes, apartments, restaurants, offices, and beyond. Each high-capacity 20” filter cartridge delivers powerful, long-lasting filtration with high flow rates, providing thousands of gallons of clean water with minimal upkeep.
Four Powerful Stages of Filtration:
Stage 1 – Sediment Filter
This initial stage targets larger particles such as dirt, rust, sand, and insect debris. By capturing these contaminants early, it helps prevent clogs and damage to your plumbing and appliances while improving the efficiency and lifespan of the filters that follow.
Stage 2 – Heavy Metal KDF Granular Activated Carbon (GAC) Filter
This is where the real purification begins. Using premium carbon media, this stage adsorbs a broad spectrum of heavy metals and chemical contaminants—including chlorine, pesticides, VOCs, industrial solvents, lead, mercury, benzene, and more. It acts as a powerful barrier against many of the most common pollutants found in household water.
Stage 3 – SoftGuard Water Softener
This filter uses a salt-free conditioning process to reduce scale buildup caused by calcium and magnesium—without adding sodium to your water. Unlike traditional softeners, it doesn't require salt, electricity, or backflushing, making it low-maintenance and ideal for extending the life of plumbing, appliances, and fixtures.
Stage 4 – Carbon Block Filter
The finishing touch. This 5-micron carbon block filter eliminates remaining tastes, odors, and discoloration caused by chlorine, chloramine, sulfur (responsible for the rotten egg smell), and trihalomethanes—harmful byproducts of water disinfection. The result is clear, fresh-smelling water that looks and feels clean.
Engineered for Strength and Durability
Built with industrial-grade materials, the NU Aqua Whole House Water Softener System is equipped with rugged filter housings, sturdy mounting brackets, and dependable, leak-resistant fittings. The large 20” filter cartridges support high flow rates—up to 15 gallons per minute (GPM)—making it a powerful solution for both spacious homes and commercial spaces.
When it's time for a filter replacement, the process is simple and straightforward. Just remove the housing, swap in a new cartridge, and keep your system running smoothly—no complex tools or procedures required.
