Improve your home's water quality with the NU Aqua Whole House Salt Free Water Softener + UV With Total Filtration. This powerful 5-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.
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.
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 filtration 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
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.
Stage 5 - UV System
Harness the power of ultraviolet light. The UV lamp delivers consistent treatment, helping protect your family without adding chemicals or affecting taste, color, or odor.
Whole-home coverage: Designed to treat all incoming water at up to 12 gallons per minute (GPM), making clean, safe water available at every faucet, shower, and appliance throughout your house.
Smart flow-activated switch: UV lamp automatically turns on only when water flows, improving energy efficiency, extending lamp life, and ensuring protection whenever water is in use.
Durable construction: Built with a 304 stainless-steel chamber and quartz sleeve for long-lasting, leak-resistant operation and reliable treatment.
Ready to install: Includes all essential components (UV lamp, power supply, mounting hardware) for straightforward integration into your home plumbing.
Versatile use: Suitable for municipal or well water and pairs effectively with pre-filtration systems to address sediment and chemical contaminants before treatment.
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.

NU Aqua System's SoftGuard Water Softener turns calcium and magnesium particles into crystals that get rid of limescale buildup in pipes and faucets.
Salt-based softeners waste hundreds of gallons of water and use tons of power. NU Aqua System's Salt-Free softeners produce no waste water and use 0 electricity.
This system's UV Smart Flow activation helps save energy and extend the life of your UV-C treatment add-on by only activating when water is flowing through it. And it does so chemical-free for water that's safe to enjoy without further filtration.
While salt-based softeners only use 1-3 stages of filtration, NU Aqua salt-free softeners use 4 stages of filtration for clean, healthy, mineral-rich water without bad taste.

And that's on top of all the other benefits you get with NU Aqua systems, like...
Salt-based softeners use resin beads that attract calcium and magnesium that cause hard water. Those beads sit in a big tub and when the resin beads are filled with particles they release salt, which softens water. However, this process creates tons of waste water and require big bulky reservoirs to operate.
Salt-free softeners like the NU Aqua 4 Stage Softener use a special filter to crystalize and neutralize calcium and magnesium. Those minerals then go through your pipes to descale and soften water without any salt exchange or bulky setup. It creates no waste water, and instead of removing calcium and magnesium, they're rendered harmless and re-added to your water to boost its ability to help your body.
