Active Plus+ cartridge with BIOTON media for the Alb Duo tap filter
The Alb Active Duo replacement cartridge is an Active Plus+ cartridge with BIOTON filter media. It has similar properties to the Active cartridge with activated carbon, but according to the manufacturer it additionally reduces bacteria and limescale. It is suitable for those who want to remove more unwanted substances from water and protect household appliances from limescale.
According to the manufacturer, the cartridge removes harmful substances, odour and bad taste, filters many bacteria, lowers water hardness by 4 to 6 °dH and improves the quality of drinking water. Price: €39.90.
How does it work and how do you replace it
The cartridge combines mechanical, adsorption and catalytic filtration with ion exchange. Mechanical filtration traps visible impurities, and ion exchange reduces limescale. It is resistant to higher temperatures (up to about 45 °C).
Replacement takes a few steps: unscrew the bottom cap of the filter (Element or Duo model), remove the old cartridge with a slight twist, insert the new one into the cap, screw the cap back on and let the water run for a few seconds to activate the cartridge. For the shower, see the Alb replacement cartridge for the Balance shower filter.
Who is it for
Choose it if you have an Alb Element or Duo tap filter and, besides taste and odour, also want to reduce limescale. The capacity is an average value, and the actual one depends on the quality of the incoming water. The flow through the filter is 6 L/min at 3 bar.
When to replace it and how to store it
Replace the cartridge every 4 months. The cartridge must always stay moist: it is delivered moist and vacuum-sealed, so do not let it dry out before installation.
