TIENS Multi-function Fridge Purifier is a modern, small, portable and easy to operate device which integrates the principles of biotechnology, electronics and mechanics together, adopting an intelligent single-chip management system to successfully apply ozone (O3) in real life. The device uses the unique properties of ozone which is known to eliminate organic and inorganic odours in household applications, e.g. in the fridge, cabinets, wardrobes and toilets. It does not mask unpleasant smells like traditional air fresheners but removes them completely. Moreover, when you put it in the fridge, it can extend the freshness of food, eliminate bacteria and exclude pathogenic fungi.
