Firstly, water is poured to the system passing through the micro-fibre mesh which removes visible dirt. Furthermore, the compact carbon trap will remove additional dirt, some parasites and some pesticides. The water then flows into the germkill processor which uses a ‘sustained release chlorine technology’ to kill harmful bacteria and viruses. Finally, the water passes through the polisher which removes odour and improves water clarity.
The germkill battery also has expiry date which is two years from the date of the packaging.
