Naturewater QF-CTO 10 Inch Activated Carbon Block Quick-Mount Household Water Filter

This cartridge filters the following from your drinking water: ozone, pesticides, rust, lime, chlorine, and reduces the concentration of heavy metals such as lead and copper. Activated carbon is known for its high efficiency and is used industrially, for example. The water used there is first treated with activated carbon before it enters our food supply, as activated carbon works very reliably and filters out most of the toxins.

Differences from other activated carbon cartridges

These filter cartridges are also referred to as post-activated carbon and are used in reverse osmosis systems alongside granular activated carbon filters and block activated carbon.
