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.

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)
• PFAS ("Forever chemicals")
• Chemicals from farms and factories
• 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:

• Softener filters: every 6-12 months
• Sediment filters: every 6-12 months
• Carbon filters: every 6–12 months

Filter costs are as follows:

• Sediment filters: $29.95
• Heavy Metal KDF GAC Filter: $99.95
• SoftGuard Water Softener: $149.95
• 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:

• 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
