The carbon filter removes foreign bodies such as dirt and rust, adsorbs odors and aftertastes, and removes over 90% of the chlorine in drinking water. The lamp assures water that is free of bacteria. The water from a Strauss Water applianceundergoes a two-stage filtration and purification process:

1. Activated carbon filtration, which includes physical filtration: particles (e.g. sand, rust and tiny stones) are physically blocked by a mesh screen; and chemical filtration: activated carbon filtration, which improves the taste and quality of the water, adsorbs the chlorine and removes aftertastes and odors.
2. UV purification, which helps to reduce the bacterial load in the water. The UV lamp emits a wavelength in a range that does not allow bacteria to continue their lifecycle.
