What's the difference between ordinary household appliances and healthy household appliances?

It is common in household appliances that people use every day. For example, the ingredients are "safe" without putting them in the refrigerator. The wind from the air conditioner may be contaminated with bacteria. Although the surface of the water heater is clear, it may not be clean.

However, healthy household appliances, such as Haier's dust-free washing machine, have subverted the design of the outer barrel and eliminated the problem of stain residue in the inner barrel from the root. Aiming at the pollution problem of the evaporator inside the air conditioner, Haier air conditioner is equipped with patented self-cleaning technology, which iterates the industry's first "air-clean integration" clean air conditioner and the clean air conditioner that effectively removes formaldehyde.
