Did you know? Oil smoke is an important source of indoor PM2.5 pollution. Speaking of PM2.5, a "health killer", many people have always thought that it only exists outdoors, especially in hazy weather. Little do they know that PM2.5 also exists indoors.

Pollution from cooking, smoking, and decoration may all produce PM2.5. Among them, the oil smoke produced by cooking can instantly pollute the air and harm the health of family members who are cooking delicious food.

A professional organization has conducted such a test on the power of oil fumes. First, the concentration of PM2.5 in the kitchen was measured when no food was being cooked. The sampling was timed for 60 seconds. The data collected was 20ug/m3 (micrograms per cubic meter), and then

I started frying eggs, and after cooking for 3 minutes without turning on the range hood, there was a smell of acrid oil smoke in the kitchen, and the concentration of PM2.5 soared to 531ug/m3.

According to the relevant national environmental assessment standards, PM2.5>300 is considered "severe pollution".

Then, the range hood was turned on to discharge the oil fumes. After three minutes, the concentration of PM2.5 in the kitchen was reduced by 70%.

However, the range hoods currently on the market are mainly first- and second-generation products.

The first generation is a mechanical version of the range hood, which can only solve the most basic needs. The second generation is a large air volume range hood, which is also the one that consumers are most exposed to at present. It can meet the needs of "large air volume exhaust fume" in a short time.

However, after being used for a long time, the range hood will accumulate oil, so the air volume will gradually become smaller, and repeated manual disassembly and cleaning will easily cause some losses.

To this end, Siemens has recently launched the third generation of self-cleaning large air volume range hoods.

Siemens' third-generation self-cleaning range hood has a smart automatic cleaning system. When the range hood has been running for 20 hours (about one to two weeks for a family of three), it will automatically remind the user to start the cleaning program and clean the inside of the range hood in time.

The grease and dirt in the core power system keep the range hood in good working condition. Even if it is used for a long time, there will be no oil accumulation problem and the air volume will not be affected.

"Self-cleaning technology has gradually begun to be recognized by more and more consumers in China. This technology is applied to range hood products, which can achieve long-term and effective smoke exhaust from range hoods." The relevant person in charge of Siemens said that it can only be obtained from range hoods.

Focus on product improvement to create a healthier living space for consumers.
