Function of the carbon block The working principle of a carbon block is a combination of mechanical filtration and adsorption by activated carbon. The carbon block is produced by pressing together carbon powder and a binder. All materials are of food grade quality.
The carbon block provides a large active surface for the adsorption of impurities. The BRITA On Tap cartridge reduces impurities in three different ways:
Bad taste and odour, chlorine (water disinfectant) and organic impurities are adsorbed. Amongst these are certain pesticides (i.e. diurone and atrazine), herbicides and by-products of drinking water disinfection (i.e. Trihalomethanes). The last ones belong to the group of VOCs (Volatile organic chemicals).
Metals like lead (emitted by old pipes) are adsorbed by an integrated metal scavenger.
Fine solid particles which cause turbidity (i.e. rust and sand) are filtered by the micropouros structure of the carbon block.
*The contaminants or substances reduced are not necessarily in all users' water.
Function of the electronic cartridge change indicator The Electronic Cartridge Change Indicator is located on top of the unit. The Indicator measures the time while the water flows through the cartridge. When the diverter is in the filtering mode, the light will blink green. Additionally a period of 3 months is measured, starting with the reset done after the installation of a new cartridge. Whatever comes first will be indicated by a flashing yellow or red light.
The Electronic Cartridge Change Indicator is designed to continue blinking green when filtering until 90% of the lifetime. From then on the light will blink yellow until the cartridge has been totally used up - then the lights will blink red.
Filter replacement The capacity of the BRITA On Tap is approximately 1200 litres or 3 months of use. The capacity of the filter represents the average consumption of a four-person household within 3 months, offering approx. 13 litres of filtered water per day.
The cartridge lifetime is primarily determined by the quality of the incoming water, which does vary from region to region. Therefore it may occur that the cartridge is exhausted before 1200 litres have been filtered or 3 months have passed. In this case the cartridge is usually blocked, which means that no or hardly any water flows through the system anymore.
Changing the filter cartridge is as simple as using the system. First of all, simply detach filter housing from diverter. Unscrew the lower cap of the filter housing and discard the entire used cartridge. Hold the cartridge over the sink when opening the housing as it may contain water. Install the new cartridge by screwing it onto the filter housing. Do not forget to reset the Electronic Cartridge Change Indicator by screwing off the top of the unit and pressing the red dot on the battery. Then press battery back and screw on the top of the unit.
