CTO Plus is a 1 micron nominal carbon block that does all of this and also reduces VOCs. If you need VOC reduction or finer filtration, choose CTO Plus. For general chlorine, taste and odour, PFAS, and chloramine reduction at high flow, CTO is the right choice.\u003c\/p\u003e\n\n\u003ch3\u003eWhat does NSF\/ANSI 42 certification mean for these filters?\u003c\/h3\u003e\n\u003cp\u003eOn the MATRIKX CTO and CTO Plus, NSF\/ANSI 42 certification — from both NSF International and WQA — covers material safety requirements only. It confirms the materials in contact with drinking water are safe. It does not certify the performance claims. Those figures are manufacturer-stated based on internal and independent laboratory testing.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is PFAS and does this filter reduce it?\u003c\/h3\u003e\n\u003cp\u003ePFAS (per- and polyfluoroalkyl substances) are a group of synthetic chemicals found in some water supplies. The manufacturer states PFAS reduction capacity of \u0026gt;36,900 litres at 5.6 L\/min for the CTO and \u0026gt;39,700 litres at 5.6 L\/min for the CTO Plus, based on \u0026gt;95% reduction at 1500 ppt.\u003c\/p\u003e\n\n\u003ch3\u003eDoes it reduce chloramine?\u003c\/h3\u003e\n\u003cp\u003eYes — both CTO and CTO Plus reduce chloramine. The manufacturer states \u0026gt;83% reduction at 3ppm, with stated capacities shown in the spec table above.\u003c\/p\u003e\n\n\u003ch3\u003eWhy choose the Jumbo 4.5\" size over the standard 2.75\" size?\u003c\/h3\u003e\n\u003cp\u003eThe larger diameter means more carbon media, which delivers higher flow capacity, longer service life, and lower pressure drop for a given flow rate. The Jumbo size suits main water line filtration and whole-house systems where flow and capacity matter more than compact sizing.\u003c\/p\u003e\n\n\u003ch3\u003eCan I use these filters with tank or bore water?\u003c\/h3\u003e\n\u003cp\u003eOnly if the water supply is microbiologically safe and adequately disinfected. These carbon blocks are not a disinfection device. If your tank or bore water is not disinfected, you need a UV system or other disinfection method upstream of or alongside this filter.\u003c\/p\u003e\n\n\u003ch3\u003eWill it fit my existing housing?\u003c\/h3\u003e\n\u003cp\u003eThe 10\" Jumbo size fits industry-standard Jumbo (Big Blue) 10\" open sump housings with a 4.5\" internal diameter. If you're unsure about housing compatibility, check your housing dimensions before ordering.\u003c\/p\u003e\n\n\u003ch3\u003eHow often should I replace it?\u003c\/h3\u003e\n\u003cp\u003eReplacement depends on water quality, flow rate, and usage. Use the capacity figures as a guide — when chlorine taste or odour returns, or when flow drops noticeably, replace the cartridge. Flush the cartridge after installation before use.\u003c\/p\u003e\u003cdiv style=\"background:#fff3cd;border:1px solid #ffc107;border-radius:8px;padding:16px;margin:20px 0;\"\u003e\n\u003cp style=\"margin:0 0 8px;font-weight:700;color:#856404;\"\u003e⚠️ Disclaimer – Collective \/ Dropship Product\u003c\/p\u003e\n\u003cp style=\"margin:0;font-size:14px;color:#856404;\"\u003eThis product is supplied \u0026amp; shipped directly by the brand via Shopify Collective.
