Fine dust in the atmosphere was designated as a carcinogen in 2013 by the WTO, and interest in the concentration of fine dust is increasing as people's lives become uncomfortable due to fine dust coming from China.

Fine dust has become an environmental factor that affects not only health, but also lifestyle and market economy, and products that meet consumers' demands to reduce the impact of fine dust in their daily lives are gaining a great response. The use of air purifiers and humidifiers that filter out fine dust (ultra-fine dust) that is mainly introduced from outside or generated in daily life is increasing.

However, the reality is that fine dust generated from home appliances that are used in close contact with users indoors is overlooked.

Metallic fine dust (carbon, copper, etc.) is emitted from internal parts such as motors and heaters applied to hair dryers, vacuum cleaners, fans, mixers, etc., which are typical products that emit fine dust among home appliances. Measuring devices are not provided.

Before the home appliances emitting the fine dust are released to the market, there is a need for a device capable of collecting fine dust emitted by the home appliance and measuring the amount of emitted fine dust.
