Naturewater UDF-20L 20 Inch Big Blue Activated Carbon Granulate Drinking Water Filter

The activated carbon granulate post-filter cartridge fits all reverse osmosis systems as a replacement filter for the existing post-activated carbon filter. This cartridge filters the following from your drinking water: ozone, pesticides, rust, limescale, 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.

Cartridge Lifespan

Sediment, ceramic, and activated carbon filters are not washable and should be replaced approximately every 6 months (DIN 1988). To ensure consistent performance of this filter cartridge, the lifespan should not exceed 8000 liters, depending on the quality of the incoming water.

Differences from Other Activated Carbon Cartridges

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