The NU Aqua 4 Stage Whole House + UV Water Filter is just what your entire house needs. From your shower to your sinks, when you want refreshing, clean water every time you turn the tap, this whole house water gives you fresh water on demand.

This professional-grade filtration system isn’t just good for your home, it’s good for restaurants, business offices, and even apartment complexes. Each stage of filtration scrubs your water of imperfections, leaving your household or business with nothing but clean water that’s safe to use, safe to drink, and free of odors. Here’s how they work:

Stage 1 - Sediment Filter

This is where it all begins. Incoming water is run through this filter to remove tiny particles from your water like rust, silt, dirt, and even insect parts. This helps assure that the water you receive is free of these contaminants and won’t clog dishwashers, ice makers, and even pores in your shower heads and faucets.

Stage 2 - Granulated Activated Carbon (GAC) Filter

The second filter your water passes through is a GAC filter. The carbon in this filter adsorbs hundreds of chemical-based contaminants including chlorine, pesticides, volatile organic compounds (VOC’s), industrial chemicals, lead, mercury, and benzene. These contaminants stick to the carbon media and leave your water free of high concentrations of chemicals harmful to your health.

Stage 3 - Carbon Block Filter

The third filter your water passes through will be the carbon block filter. A 20 inch compressed 5-micron carbon block filter polishes your water before it hits the faucet. Here the water is polished and filtered to remove bad taste and odor-causing chemicals like chlorine, chloramine, sulfur (that rotten egg smell), and even trihalomethanes, which are byproducts of disinfectants and cause cancer.

Stage 4 - UV System

Harness the proven power of UV-C treatment to neutralize harmful contaminants right at the point of entry. The UV lamp delivers consistent filtration with a treatment rate of up to 99.99%, helping protect your family against waterborne contaminants without adding chemicals or affecting taste, color, or odor.

Features and Benefits of the Additional UV System:

• 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 UV-C treatment.

Of course, none of this would be possible without high-quality components. The NU Aqua 4 Stage Whole House system offers industrial-grade components, from the filter housing to the mounting brackets and all connections. With high capacity, 20” cartridges in each filter housing you’ll be able to filter thousands of gallons of water without fouling. When it’s time to change filters, it’s a simple as taking off the filter housing, slipping in the replacement cartridge, and putting the housing back on.

Whether you need clean water for your entire apartment complex, lots of water for your business, or you just want refreshing water from every faucet in your home, the NU Aqua 4 Stage Whole House Water Filter is exactly what you need. Take better showers, make better coffee, and give yourself the clean, refreshing water you deserve.
