The drain clean system

The Product

Invented and designed in Denmark, with a documented effect. It consists of a device installed on sink drainpipes that removes and prevent bacteria from developing. The device consists of two parts. A steel mount which is mounted on any sink drainpipe above the trap, and a UV-C lamp which ensures that all particles moving through the steel mount are directly exposed to UV-C light which burns the DNA/RNA of bacteria and biofilm. The UV-C lamp has a lifetime of 9 000 hours.

Effectively removes

  • Biofilm
