Defender iGen C
Whole-house softening and chlorine/chloramine filtration in a polyethylene-lined fiberglass tank.
Summary
The Defender iGen C is a three-stage whole-house system that softens water and reduces chlorine and chloramine at every tap. It combines ChloroShield Clearess filter media, high-capacity softening resin, and a clarifier layer in one multi-layer tank controlled by the iGen smart valve.
Who should consider it
- Homes on municipal (chlorinated or chloraminated) water with hardness.
- Households that want one point-of-entry system for softening plus chlorine and chloramine taste-and-odor reduction.
- Homeowners who prefer a system without scheduled media cartridge changes under normal municipal conditions.
Treatment role and limits
Role: Whole-house softener and chloramine/chlorine filter combination (point of entry)
Intended water: Municipal water, or private well water that is disinfected with chlorine or chloramine. For private wells without chlorine or chloramine, Puronics directs dealers to the base version of the system without the Clearess media.
Limits
This system softens water and reduces chlorine and chloramine taste and odor. Its certifications cover hardness, barium, radium 226/228 and chlorine taste and odor, plus low-lead construction of the unit. It is not certified to reduce lead, arsenic, nitrate, PFAS, bacteria or viruses from water, and it is not a treatment for an undisinfected well. For those needs see laboratory testing and reverse osmosis.
What makes this model different
The most straightforward of the three C-series combination systems: same media and valve, with a fiberglass-wrapped tank.

Verified specifications
- Model
- Puronics Defender iGen C
- Treatment role
- Whole-house softener and chloramine/chlorine filter combination (point of entry)
- Tank / housing
- Multi-layer tank: polyethylene inner layer with a fiberglass outer layer
- Media
- ChloroShield Clearess filter media (Chlorostatic technology), high-capacity S-759 monospheric softening resin, and a silica-gravel clarifier layer
- Control valve
- Patented iGen computerized control valve: keeps 60 days of water-usage history to time backwash/recharge, double backwash, built-in diagnostics, automatic reserve, 1-inch corrosion-resistant valve body, downflow brining
- Regeneration
- Regenerates with sodium chloride (salt) or potassium chloride; the brine tank is separate from the media tank
- Media capacity
- Puronics rates the Clearess media to reduce chloramine/chlorine taste and odor for up to 2,600,000 gallons of municipal water at normal service flow rates. NSF/ANSI 42 testing was performed at 2.0 ppm chlorine; the published capacity is extrapolated for lower influent concentrations. Higher chlorine or chloramine levels may shorten media life.
- Strontium
- Puronics states "effective reduction of strontium as verified by independent test data." No certification standard is named for this claim.

Certifications
Defender iGen C is Water Quality Association tested and certified to 42, 44, 372 (NSF/ANSI). The table lists exactly what each standard covers.
Puronics states the system is Water Quality Association tested and certified to the following standards. Certification applies to the listed claims under the test conditions of each standard.
| Standard | What it covers | Notes |
|---|---|---|
| NSF/ANSI 42 | Reduction of chlorine, chlorine taste and chlorine odor (aesthetic) | Chloramine reduction is a manufacturer performance claim; it is not listed under this standard on the product page. |
| NSF/ANSI 44 | Reduction of hardness minerals, barium, and radium 226/228 (cation-exchange softener) | |
| NSF/ANSI 372 | Lead-free compliance of wetted components. This is a low-lead construction standard, not a claim that the system removes lead from water. |
NSF/ANSI 372 is a lead-content standard for the product's wetted materials. It is not a water-treatment performance claim. WQA listings should be re-verified at wqa.org/Find-Products for the exact model and date before relying on them.
Care and ownership
- Keep the brine tank stocked with softener salt or potassium chloride.
- The iGen valve manages backwash and recharge automatically; no scheduled cartridge changes are required for the Clearess media under normal municipal conditions.
- Operational maintenance and replacement requirements are essential for the product to perform as advertised (manufacturer disclaimer).
- A drain and a standard electrical outlet are required for the control valve.
Warranty
Puronics states the ChloroShield Clearess media carries a limited lifetime warranty and "reduces the need for filter changes." The manufacturer product page does not publish full warranty terms for the complete system; the written warranty document governs. We will provide it with any quote.
"Limited" means the warranty has conditions and exclusions. We will not describe any warranty as covering labor, consumables, or every component unless the written document says so.
Other configurations
Other Puronics configurations may be recommended based on your water assessment. The three C-series systems share treatment media and valve; sizing and, for undisinfected wells, a base configuration without Clearess media, follow your test results.
Contaminants or other substances which can be reduced by this system are not necessarily present in your water.
Defender iGen C questions
Does the Defender need filter changes?
Puronics states the ChloroShield Clearess media carries a limited lifetime warranty and reduces the need for filter changes. There is no cartridge to swap under normal municipal conditions; the iGen valve backwashes the media automatically. Media life is rated at up to 2,600,000 gallons of municipal water at normal flow, and higher chlorine or chloramine levels may shorten it. You still add salt or potassium chloride for the softening side.
What is the difference between the Defender and the Hydronex?
The treatment is the same. The Hydronex adds a stainless-steel outer cover over the lined composite tank; the Defender tank is polyethylene inside with a fiberglass outer layer. See the comparison.
Will it work on my well?
If the well is disinfected with chlorine or chloramine, yes. For a well without disinfection, Puronics directs dealers to the base version without Clearess media, and a certified lab test should come first.
Is the Defender iGen C right for your water?
The only way to know is to test. We measure your water at home, explain the results, and recommend the configuration that fits, which may be this system or another.
