NU Aqua Heavy Metal Whole House Water Filtration System – 3-Stage Filtration for Clean, Safe Water Everywhere
Elevate your home's water quality with the NU Aqua Heavy Metal Whole House Water Filtration System—a powerful, 3-stage filtration solution designed to deliver fresh, clean water to every faucet in your home or business. From the kitchen to the shower, this system ensures your water is free from harmful contaminants, heavy metals, and unpleasant odors—so you can enjoy healthier water for drinking, cooking, bathing, and more.
Engineered for Performance. Built for Peace of Mind.
Whether you're upgrading your home’s water system or outfitting a commercial space, this professional-grade system is built to handle it all—homes, apartments, restaurants, office buildings, and more. Each high-capacity, 20” filter cartridge is designed for maximum flow and long-lasting filtration, giving you thousands of gallons of clean water with minimal maintenance.
Three Powerful Stages of Filtration:
Stage 1 – Sediment Filter
This first line of defense removes larger particles like dirt, rust, sand, and insect debris. Not only does this protect your plumbing and appliances from clogs and wear, but it also enhances the performance of the following filters.
Stage 2 – Heavy Metal KDF Granular Activated Carbon (GAC) Filter
Here’s where the chemistry happens. This stage uses high-grade carbon media to adsorb a wide range of heavy metals and chemical contaminants, including chlorine, pesticides, VOCs, industrial solvents, lead, mercury, benzene, and other toxic compounds. It’s your shield against many common household water pollutants.
Stage 3 – Carbon Block Filter
The final polish. This 5-micron carbon block filter removes any lingering tastes, odors, and discoloration caused by chlorine, chloramine, sulfur (that rotten egg smell), and trihalomethanes (cancer-causing byproducts of water disinfection). The result is crisp, clean water that tastes as good as it looks.
Heavy-Duty Construction for Long-Term Reliability
Crafted with industrial-grade components, the NU Aqua Heavy Metal Whole House System features durable filter housings, secure mounting brackets, and reliable, leak-resistant connections. The oversized 20” cartridges are designed to handle high flow rates—up to 15 gallons per minute (GPM)—making it ideal for large homes and commercial properties alike.
When it’s time for a filter change, maintenance is quick and hassle-free. Simply remove the housing, replace the cartridge, and enjoy continued clean water with no complicated procedures.

Frequently Asked Questions (F.A.Q.)
A whole home heavy metal water filter cleans a whole host of contaminants from your water, including:
- Dirt, sand, and rust
- Chlorine (the stuff that makes water smell like a pool)
- Chemicals from farms and factories
- PFAS ("Forever chemicals")
- Heavy metals like lead and mercury
- Other harmful stuff like nitrates and arsenic
- Bad taste and smells
The best part: that clean water comes out of every faucet.
Whole home filters can take out the majority of contaminants from your water.
And their ability to get rid of contaminants depends on factors like:
- The quality of filters used in the system
- How durable the filter housings and assembly are
- The contaminants in your water
- How often you change your filters
That's why top quality systems- like the ones you find at NU Aqua Systems- can remove the majority of contaminants in your water because
- NU Aqua only uses high quality filters in each system that can filter contaminants in thousands of gallons of water
- NU Aqua whole house systems are made with top quality materials that hold up to years of use
- NU Aqua also send alerts and reminders for you to maintain your system for maximum filtration and clean water output.
The difference between the two comes down to how many faucets you can move clean water through:
- A whole home filter cleans all the water that comes into your house. That way every sink, shower, and appliance gets clean water.
- A point-of-use filter only cleans water at one spot, like your kitchen sink.
Whole home filters cost more but give your whole house clean water. Point-of-use filters cost less but only clean one place.
Yes, most of the time. Whole home filters are big and connect to your main water pipe. A plumber usually has to:
- Cut into the pipes
- Make sure it fits right
- Test for leaks
- Follow the city’s rules
Trying to do it yourself could cause leaks or water damage, so it’s best to hire a pro.
You need to change filters to keep water clean. How often depends on your water and your system:
- Sediment filters: every 6-12 months
- Carbon filters: every 6–12 months
Filter costs are as follows:
- Sediment Filters: $29.95
- Heavy Metal Granular Carbon Filter: $99.95
- Carbon Block Filter: $39.95
You have to take care of your filter so it lasts. This may include:
- Changing the filters (every 6–12 months, depending on the type)
- Cleaning parts of the system
- Checking for leaks
- Making sure water pressure is good
Some people hire a water expert once a year to check everything.
NU Aqua whole house systems last indefinitely with the proper maintenance:
- On-time filter exchanges
- Routine cleaning
- Replace O-Rings every 3 years
- Replace teflon tape on all threaded connections & fittings every 3 years.
- Replace filter housings every 5 year.
There's a slight drop in water pressure of around 2-3 PSI when installed.
However, without proper maintenance and upkeep, water pressure will drop even further. This includes factors like
- Clogged filters
- Pressure valves aren't open all the way
- Faulty pressure regulator
Yes. A whole home filter needs:
- To be put on the main water pipe where water enters your house
- 1" pipes that fit the filter connections
- Shut-off valves so you can turn water off for cleaning
- Enough water pressure (usually between 20–80 PSI)
- Sometimes a permit or inspection from your city
Customer Reviews
I had this unit installed a couple years ago, and the water quality has been excellent!! I would recommend this whole House system to anyone and I have many time!!!
This product is the best thing I’ve ever bought for my house. No chlorine no fluoride nothing. I test the water regularly and it comes back zeros every time. Highly recommend.
Family of three and two dogs have been using this whole house filtration system for 3.5 months. Immediately after installation, the water was softer and odor disappeared. The water tastes better. I also think I see some modest improvements in our family’s skin health: less back breakouts for dad, smoother skin for the little one, and less dryness for mom. We had a plumber install the system. We have not changed filters yet. So far so good.
Built like a tank with nice looking gauges.
Important to mention, in several posts on the questions section, the company Nu Aqua has stated the dimensions of the unit to be 24.25" x 7.75" x 27.75" (LWH) THIS IS INCORRECT. It almost made my install not work.
THE UNIT IS 30.5" (H) from the rubber feet to the top edge of the mounting plate of the frame. Might not affect too many people, but it made my limited space install very close to not working.
So far it's been a great addition to my water treatment. Lower dissolved solids by 57% right away after install. Expect it to improve out garden health and very happy to have clean water coming into the showers. We previously used shower filters. This should also extend the life of filters for my 7 stage RO filter from Nu Aqua.
4.5 stars initial response.
