Our Salt-Free Softeners Exceed Salt Based Softeners

Feel the NU Aqua Difference
NU Aqua System's SoftGuard Water Softener turns calcium and magnesium minerals into crystals that remove and prevent scaling.
Most softeners wastes hundreds of gallons of water and electricity, but NU Aqua saves both. No waste water, no electricity- that's good for your budget and the environment.


Unlike most 1-3 stage softeners, NU Aqua softeners use 4 stages of filtration for clean, healthy, mineral-rich water without bad taste.

Frequently Asked Questions (F.A.Q.)
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 readded to your water to boost its ability to help your body.
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
- Germs like bacteria and viruses (with the right filter)
- Heavy metals like lead and mercury
- Other harmful stuff like nitrates and arsenic
- Bad taste and smells
And the best part: that clean water comes out of every faucet, unlike point-of-use filters that only work for a single 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 take out 90–99% of the bad stuff in your water because
- We only use high quality filters in each system that can filter contaminants in thousands of gallons of water
- Our systems are made with top quality materials that hold up to years of use
- We 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: about every 6 months
- Carbon filters: every 6–12 months
- Special filters: about once a year
Costs can be:
- Sediment filters: about $30
- Carbon filters: $40–50
- Big tank filters: $50–300 or more
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.
It depends on the system and how well you take care of it.
- Cheaper systems may last 5–10 years.
- Good systems can last 10–20 years or more.
If you keep it clean and change filters on time, it will last longer.
Yes, a little. All filters slow water down some.
- You may notice the water pressure is a little lower.
- If you don’t change the filters on time, it can get worse.
- If the filter is too small for your house, the water flow may drop a lot.
A properly sized system should give you plenty of water for normal use.
Yes. A whole home filter needs:
- To be put on the main water pipe where water enters your house
- 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
Some systems may also need power or extra parts depending on your home.
