Naturewater 20Inch - 508mm 5µ Activated Carbon Block Filter Insert CTO-20B

The activated carbon filter cartridge fits all reverse osmosis systems with 20" filter housings. This cartridge filters the following substances from your drinking water: ozone, pesticides, rust, lime particles, 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 treated with activated carbon before it enters our food supply, as activated carbon works very reliably and filters out the majority of toxins.

Cartridge lifespan

In a household of four people, such a cartridge lasts about 9 months with average water consumption. After that, it can no longer adsorb the aforementioned toxins from the water. However, the legislator specifies other timeframes in which these cartridges must be replaced. According to DIN 1988, it is stipulated that all cartridges must be renewed every 6 months, as otherwise there is a risk of bacterial growth.

Differences from other activated carbon cartridges

These filter cartridges are also referred to as block activated carbon and are used in reverse osmosis filter systems alongside post-activated carbon filters and granular activated carbon filter cartridges. All filter cartridges are, of course, available in the usual high quality.
