Reduces chlorine, taste and odour, and running ahead of the NAC keeps chlorine off the media. Replaced yearly. Made for water supplies disinfected with chlorine, as Perth's and most of WA's are.

Placed last, it conditions your water at the point it heads off into your home, shielding the pipework, hot water system and appliances downstream from scale. Running the carbon stage ahead of it keeps chlorine off the SP3 media, so nothing disrupts the crystal formation it relies on.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's in the box:\u003c\/strong\u003e the two sealed cartridges, the NAC media bag, the refill instruction card and a sachet of food-grade silicone grease for the O-rings.\u003c\/p\u003e\n\u003cp\u003eAbout twenty minutes with the housing wrench and no plumber. The carbon block moves to the middle and the NAC cartridge runs last. Rather not?

Instead of softening your water by stripping out minerals, it conditions it, converting dissolved calcium into harmless aragonite microcrystals that flow straight through your pipes, elements and glassware without bonding to anything. The minerals stay in your water. Only their ability to form scale is reduced. No salt, no wastewater, no electricity.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe honest trade-off:\u003c\/strong\u003e if you specifically want that soft water feel on your skin and hair, traditional resin softening still does that and NAC doesn't, because it deliberately leaves the minerals in. But if your goal is protecting your pipes, hot water system and appliances from scale with minimal upkeep, NAC is the better long term choice.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe difference in kind:\u003c\/strong\u003e resin is consumed by the softening it does. Its capacity is strongest in the early weeks of a fresh refill and tapers as it's used up, which is why the soft water feel fades before the refill is due. NAC isn't consumed by the crystallisation it drives, so it works the same in month twenty as it does on day one.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCertification:\u003c\/strong\u003e FILTERSORB SP3 is certified to NSF\/ANSI\/CAN 61 and NSF\/ANSI\/CAN 372 by the Water Quality Association (WQA) and IAPMO for safe use in potable water systems, with additional international drinking water approvals including WRAS and BS 6920 (UK). These are material safety certifications, not a performance certification.\u003c\/p\u003e\n\u003cp\u003eNot sure it's your system?
