In terms of household oil fume pollution control, Shenzhen is formulating special technical specifications for the purification rate of household range hoods.
After the introduction, the sale of range hoods with a degree of oil separation of less than 90% will be prohibited throughout the city, which will effectively improve household range hoods.
The oil fume purification rate reduces pollution emissions.
