Ultraviolet sterilization and high-temperature sterilization in washing machines are two different sterilization methods, each with its own advantages and applicable scenarios.
1, Ultraviolet sterilization: Principle: the use of ultraviolet light (usually C-band ultraviolet, that is, UV-C) to destroy the DNA or RNA structure of microbial cells, so that they lose the ability to replicate, so as to achieve the effect of sterilization.
Advantages: good inactivation of most bacteria and viruses; does not produce harmful chemicals, friendly to the environment; less physical damage to clothing.
Disadvantage: For heavy, folded or stacked laundry, the UV light may not reach all surfaces directly, so the sterilization effect may not be uniform.
2. High temperature sterilization: Principle: Killing or inactivating microorganisms by raising the water temperature. It is generally believed that a water temperature of 60°C or above can effectively kill most common bacteria.
Advantages: the sterilization effect is more thorough and works on all parts of the clothing; it also removes stains from clothing.
Disadvantages: High temperatures may cause some materials to shrink, deform or fade; relatively high energy consumption; for some sensitive fabrics (e.g. silk, wool, etc.), high temperatures may cause damage.
Suggestion: If your clothes are heat-resistant and need to be thoroughly cleaned and sterilized (e.g. bedding, towels, etc.), then high temperature sterilization may be a better choice. For delicate fabrics that can be easily damaged or for clothing that needs a gentle treatment, UV sterilization may be more appropriate. Which you ultimately choose depends on your specific needs and personal preference. Some washing machines may offer both sterilization modes, so you have the flexibility to choose on a case-by-case basis.
