Haier's self-cleaning air conditioner can thoroughly clean the heat exchanger of air conditioner and ensure air health by using four patented technologies: cold expansion patent technology, condensation patent technology, sapphire coating patent technology and antibacterial patent technology. But this is just cleaning the internal machine, and the water generated by cleaning needs to be naturally dried.
Although Hisense's air conditioners lack some patented coatings, their functions are the same. Of course, Hisense also has corresponding advantages. Hisense has a unique way to make the internal and external machines independent and clean. It carries out more thorough and healthy self-cleaning through five steps: frosting, infiltration, wrapping, expansion and peeling, defrosting, drying and bacteriostasis. The key is to realize automatic drying after cleaning.
To sum up, Haier has a unique antibacterial coating, but only the inside of the machine is clean and not dried. Hisense's new model has independent internal and external cleaning belts for drying. It is recommended to look at the specific models of the two brands and do what you can according to your own budget.
