Environmental protection refers to the impact of commercial range hoods on environmental pollution, mainly including noise, waste gas, lampblack and other factors. At present, many commercial range hoods on the market have adopted high-efficiency purification technologies, such as electrostatic removal, high-efficiency filter screen and activated carbon adsorption. , effectively reducing the emission of harmful substances such as waste gas, oil fume and odor, thus greatly improving the environmental protection level of commercial range hoods.

Smokeless means that the smoke concentration in the kitchen is low after the commercial range hood is operated, that is, the existence of visible smog, colored impurities and odor gas in the air is reduced. The smoke with rising temperature generated by extracting oil fume is finally discharged after being treated by the filter device of commercial range hood, so as to reduce the smoke entering the restaurant and maintain a good indoor environment.

It should be noted that "smokeless" does not mean "smokeless". Only under the reasonable food processing operation, can we try our best to avoid the pervasion of oil fume, and at the same time, we should buy suitable commercial range hoods and maintain and clean them regularly. In addition, the restaurant should also do a good job in the reasonable layout of the smoke exhaust system and air purification management to ensure that the indoor environment meets the standards and better meet the health needs of customers.
