CTO is commonly used in carbon cartridge labelling for chlorine, taste and odour duty. The label alone is not a complete specification. Confirm the exact media construction and manufacturer’s rated performance for the proposed in-line element.
| Identification | Provide the full CTO cartridge label and manufacturer/model if known. |
|---|---|
| Media | Confirm the quoted element’s carbon construction instead of inferring it from the acronym alone. |
| Fit | Check body clearance, inlet/outlet size and connection style. |
| Treatment duty | Request the model-specific reduction claims, flow and replacement requirements. |
These are common reference formats to help prepare your enquiry. They are not a stock list or confirmed specifications for one supplied model.
| Micron / selection basis | No single standard particle rating |
|---|---|
| Size / configuration | Often a sealed body around 10 in long; model dimensions and connections vary. |
| Important check | CTO labelling alone is not a complete media, capacity or compatibility specification. |

Replacement timing and any flushing, sanitisation or service procedure depend on the selected model and application. Confirm the manufacturer instructions and any included installation work.
