Is the water purifier really as useful as advertised?

The core technologies of regular brands are the same, but the focus is on post-service, because the filter element needs to be replaced, otherwise it is difficult to ensure the quality of the effluent.

Suzhou Runte Direct Drinking Water adopts a subversive sales model, providing water purifiers free of charge, charging according to consumers' water consumption, replacing filter elements twice a year, testing water quality twice for free, and replacing new machines for three years! All services in the later period are free! Annual signing method
