Question about Sogo Retro Strix Control cordless kettle

The kettle's base station must be connected to a socket using the integrated cable. The kettle itself can then be placed wirelessly on this station to bring the water to the boil.

The manufacturer provides the following additional information:

1.8 litre metallic red lacquered
stainless steel kettle
- Integrated thermometer for current liquid temperature
- High-quality Strix control for maximum safety and work efficiency
- Transparent water level indicator
- Removable filter
- Dry boil protection
- Protection against overheating
- 360° base with cable protection
- Body with cold touch and scald protection
- Automatic switch-off

Unfortunately, it does not provide any information on the material of the filter or whether the water only comes into contact with stainless steel.
