överfyllnadsfilter
An överfyllnadsfilter, often translated as an overflow filter, is a type of filter used in plumbing systems to prevent overflow from a sink or basin. It is typically installed in the overflow outlet, a small hole located near the top rim of the fixture. When the water level rises and reaches this opening, it enters the overflow channel and passes through the filter before exiting the plumbing system.
The primary function of an överfyllnadsfilter is to trap debris and hair that might otherwise be washed
