Frequently asked questions
The SCB reduces chlorine, taste and odour, and also helps with VOC and THM (trihalomethane) reduction — it's commonly used for general drinking water polishing and as a protective pre-filter stage ahead of an RO membrane.
It's extruded from fine, acid-washed powdered activated carbon bonded with food-grade additives into a solid block, then sintered for improved flow and dirt-holding capacity, with an outer polypropylene wrap that captures sediment and protects the carbon block itself.
The outer polypropylene wrap does capture some particulate, but the SCB's primary job is adsorption (chlorine, taste, odour, VOCs) rather than sediment removal — for water with significant sediment, we'd recommend a dedicated sediment pre-filter ahead of the SCB to protect it and extend its life.
Typically every 3-6 months for domestic use, though this depends on your water quality and usage — carbon's adsorption capacity doesn't give an obvious warning sign, so it's best to replace on a schedule rather than waiting for taste or odour to return.
Yes — carbon block is a standard pre-filter stage ahead of an RO membrane, since it removes the chlorine that would otherwise degrade the membrane over time, alongside general taste and odour improvement.
