Whole-Home Filtration + Softening · Consultation Required
Filtered, softened water at every tap.
One system does it all.
The Hydronex C is GoodFor's flagship whole-home water filtration and softening system — certified to NSF/ANSI 42, 44, and 372 by the Water Quality Association, with proprietary Clearess® catalytic carbon media rated for approximately 2.6 million gallons. It is the system we match to roughly 95% of homes on municipal water, and it carries a limited lifetime warranty for the original purchaser.

What It Addresses
Certified where it counts. Honest everywhere else.
The Hydronex C is certified by the Water Quality Association to NSF/ANSI 42 for chlorine taste and odor reduction, NSF/ANSI 44 for hardness, barium, and radium 226/228, and NSF/ANSI 372 for lead-free material compliance.
Chlorine — NSF/ANSI 42
Clearess® media reduces chlorine taste and odor at concentrations up to 4 ppm — a level most whole-home systems are never tested against.
Hardness — NSF/ANSI 44
Ion exchange softening removes calcium and magnesium, along with barium and radium 226/228, delivering genuinely soft water to every fixture and appliance.
Lead-Free Materials — NSF/ANSI 372
Every wetted component meets the NSF/ANSI 372 low-lead standard, so the system itself never adds what you're filtering out.
Chloramine — up to 4 ppm
Clearess® media is built to reduce chloramine — the disinfectant most Southern California utilities now use — at up to 4 ppm by design.
THMs, VOCs & PFAS
As a proprietary catalytic carbon, the Clearess® media bed can also help reduce trihalomethanes, volatile organic compounds, and PFAS (PFOA/PFOS) through adsorption — by-design capabilities, not certified claims.
Iron in Hardness
Softening resin reduces dissolved (ferrous) iron carried alongside hardness minerals, protecting fixtures from staining.
GoodFor separates certified claims from by-design capabilities on every page: NSF/ANSI 42, 44, and 372 are WQA-verified for this system; chloramine, THM, VOC, and PFAS (PFOA/PFOS) reduction are by-design capabilities of the Clearess® catalytic carbon media and are not NSF-certified claims — for certified PFAS reduction, see the Pioneer Pb add-on or the MicroMax 8500 at the sink. Learn how to read certification claims on our NSF certifications guide.
How It Works
Two media beds. Zero scheduled filter changes.
The Hydronex C treats water in two stages inside a single tank: Clearess® media reduces chlorine and chloramine, then S-759 cation exchange resin removes the hardness minerals that cause scale.
Clearess® Filtration
Chloroshield™ Clearess® — a proprietary catalytic carbon — reduces chlorine and chloramine as water enters the home. It is rated for approximately 2.6 million gallons at 0.5 ppm chlorine — around 18–20+ years of typical residential use with no scheduled filter replacements.
Ion Exchange Softening
S-759 cation exchange resin captures calcium and magnesium and releases them during regeneration, protecting water heaters, pipes, glass, skin, and hair from hard-water effects. The system regenerates automatically and uses nugget or pellet salt only.
Specifications
The numbers behind the system.
The Hydronex C ships in two residential sizes — 1" for homes with up to 5 bathrooms and 1.25" for 6 or more — and both deliver the same 14.9 GPM flow rate.
The GoodFor Difference
Why homeowners choose the Hydronex C through GoodFor.
A whole-home system is a 20-year decision. The Hydronex C earns it with verified certifications, American manufacturing, and a warranty structure that is among the strongest in residential water treatment — see how we compare.
Limited Lifetime Warranty
The tank, valve head, S-759 resin, and Clearess® media are covered for the lifetime of the system for the original purchaser; electronic components are covered for 5 years. Register within 30 days of purchase to activate coverage.
Made in the USA
Every Hydronex C is manufactured in Livermore, California by a partner with more than 75 years in water treatment — and serviced by GoodFor's licensed team, led by a California Licensed Master Plumber (CSLB #1102129).
Matched to Your Water
GoodFor never guesses. Your free consultation reviews your utility's water quality data, your home's size and plumbing, and your goals — then matches you to the right certified system. If the Hydronex C isn't the fit, we'll tell you what is.
Certified, Not Claimed
Every performance number on this page traces to a WQA-verified NSF/ANSI standard or is clearly labeled as a by-design capability — the same standard of honesty we bring to how water softeners work.
Find Your Fit
Not sure the Hydronex C is your system?
The Hydronex C is the right match for most municipal-water homes that want genuinely soft water — but GoodFor carries certified systems for every situation.

Common Questions
Hydronex C questions, answered.
Is the Hydronex C a water softener or a water filter?
Both. The Hydronex C combines two treatment stages in one tank: Chloroshield™ Clearess® media reduces chlorine and chloramine (NSF/ANSI 42 certified for chlorine taste and odor), and S-759 cation exchange resin softens the water by removing calcium and magnesium (NSF/ANSI 44 certified). That combination is why it's GoodFor's default recommendation for roughly 95% of homes on municipal water.
Does the Hydronex C reduce chloramine or PFAS?
Yes to both, with an honest distinction. The Clearess® media is built to reduce chloramine at concentrations up to 4 ppm, covering typical municipal levels with significant headroom — and because it is a proprietary catalytic carbon, it can also help reduce PFAS (PFOA/PFOS) through adsorption. Both are by-design capabilities of the media rather than NSF-certified claims; for certified PFAS reduction, GoodFor offers the Pioneer Pb whole-home add-on (97.9% PFOA/PFOS, NSF/ANSI 53) and the MicroMax 8500 at the kitchen sink — the system's certified claims are NSF/ANSI 42 (chlorine taste and odor), 44 (hardness, barium, radium 226/228), and 372 (lead-free materials), verified by the Water Quality Association.
How long does the media last, and what maintenance is required?
The Clearess® media is rated for approximately 2.6 million gallons at 0.5 ppm chlorine — around 18 to 20+ years of typical residential use — with no scheduled filter replacements. Routine ownership comes down to keeping the salt tank stocked with nugget or pellet salt (never rock salt) and letting the system regenerate automatically.
Does softened water add sodium?
A small amount. Ion exchange softening adds roughly 20 mg of sodium per 8-ounce glass at 10 grains of hardness — for perspective, a single slice of bread contains around 160 mg. Most households never notice it; if anyone in your home is on a sodium-restricted diet, raise it during your consultation and we'll walk through options, including pairing the system with reverse osmosis at the kitchen sink.
Why isn't there a price on this page?
Whole-home systems are sized to your home's plumbing, bathroom count, and water chemistry, and quotes include the correct model size for your situation — so pricing is provided during a free consultation rather than as a one-size-fits-all number. The consultation is free, carries no obligation, and is available in person across Southern California or virtually anywhere in the US.
What does the limited lifetime warranty cover?
For the original purchaser, the tank (vessel), valve head, S-759 softening resin, and Clearess® filtration media are covered for the lifetime of the system. Electronic components in the head — control board, display, sensors — are covered for 5 years. The warranty card must be returned within 30 days of purchase to activate coverage, and coverage does not transfer if the home is sold.
