generally speaking, there may be several problems in the exhaust volume of range hoods: loud noise, dust emission, difficulty in cleaning, etc. Therefore, some measures should be taken to solve these problems.

first, you can consider installing a silencer. Silencer can effectively reduce the noise of range hood and make it more comfortable to use. Secondly, multi-stage filtration can be used to effectively improve the dust emission. The adoption of multi-layer composite filter screen structure can effectively absorb oil fume, odor and dust in the air, and achieve the effect of purifying the air.

Secondly, when installing a range hood, you can try to choose a down-pressure range hood and discharge it downward through the exhaust port of the range hood, which can effectively prevent the upward lampblack and smell from disturbing other areas in the kitchen. At the same time, it is convenient for daily cleaning and can clean the inside and outside of the range hood more thoroughly.

Finally, attention should be paid to the design of the exhaust duct. The exhaust duct needs to be designed in a straight line and without angles (if possible, it is best to use 81mm duct), which can improve the exhaust efficiency of the range hood, avoid dust accumulation, and further reduce oil leakage smoke and odor.

In short, in order to solve the problem caused by the large exhaust volume of range hoods, some measures need to be taken, such as installing silencers, using multi-stage filters, selecting down-pressure range hoods, etc., and designing the pipes according to the actual situation.
