Do household appliances need a desiccant to prevent moisture?

Household appliances generally do not need additional desiccant, but electronic equipment such as computers, after accumulating dust, is easy to cause the motherboard to be short-circuited and burned during the rainy season. Similarly, home TVs, game consoles, and audio amplifiers all have a common feature, which is easy to accumulate dust.


If you are an enthusiast of such products, remember to disassemble and clean up the dust!
