Recently, the topic of bad Xi cooking that may cause family cancer has become the focus of hot searches, which has aroused the attention of the majority of social **.
Among them, a bad Xi that is easy to be ignored and easy to be tricked is not to turn on or off the hood early.
A survey by the Cancer Institute of Tongji University in Shanghai found that the risk of lung cancer increased by 2 3 times in middle-aged and elderly women due to long-term exposure to high-temperature oil fumes. Among the risk factors for lung cancer in non-smoking women, more than 60% of women are chronically exposed to kitchen fumes.
Many housewives and cooks may experience various physical discomforts after cooking, such as nausea, loss of appetite, throat discomfort, dizziness, headache, chest tightness and tinnitus, etc., which are closely related to the oil fumes produced during cooking.
Therefore, the range hood becomes a must-have equipment in the kitchen. But in real life, some people treat it as an ornament, rarely open it, and almost become an idle item.
Always turn on the hood during cooking and pay special attention to how long the hood is in use.
According to research, turning on the hood within 20 seconds of cooking can more effectively control the distribution of fumes and prevent them from spreading. During the whole cooking process, you need to keep the hood on continuously and let it continue to run for 3 minutes after cooking, and do not turn it off immediately after cooking, which can effectively remove the residual oil smoke.
In addition to oil smoke, the main sources of pollution in kitchens include carbon monoxide, carbon dioxide, sulfur dioxide and other harmful gases released from coal gas and liquefied gas. Although the range hood can effectively extract most of the fumes, the remaining polluting gases and odours may still spill into other parts of the room (such as the living room), causing harm to human health.
In order to solve this problem, an effective way is to install a fresh air system. The fresh air system is to inhale the fresh air outside, remove the dirty air in the room, and effectively replace the obsolete air in the room, so as to reduce the accumulation of harmful gases and odors in the room.
Dr. Hu fresh air system adopts two-way flow working mode, which can effectively discharge the harmful gases accumulated in the room through forced air supply and exhaustBuilt-in H12 high-efficiency HEPA filter, which can effectively filter PM25 particulate pollutants, as small as 0The filtration efficiency of 5 m particulate pollutants is 995% (only 1 particle out of every 20 million ultra-small particles can pass through the HEPA filter). This means that compared with other fresh air systems, Dr. Hu fresh air system has stronger filtration capacity, which can more effectively remove kitchen oil and odors, making the indoor air fresh and clean, and more protective for human health.
