Question: No frost

The frost free means when you use refrigerator,it does not need to defrost manually,but it doesn't mean the refrigerator is "no frost"

About Haier models with frost shield system, it also does't mean frost free, it could reduce about 70% frost.

So in summer, about the refrigerator with this system ,you can defrost every three or four months.But about the refrigerator without this system,it need to defrost every month.
