It is believed that in addition to formaldehyde, many people may choose ventilation. In a word, air purchase is only a matter of time. Let's not say that it's wrong not to be able to ventilate formaldehyde, but ventilation should also pay attention to methods. Especially in our daily life, ventilation is also very important. Proper and effective ventilation formaldehyde exceeds the standard, that is, there is no such problem. Why ventilation has no effect except formaldehyde Need technology.
Ventilation should also be frequent. It is believed that everyone will keep the indoor ventilation environment, even before checking in at the window one day, but there is a special time. This is whether we have enough ventilation time in summer and winter, because air conditioning can be turned on in summer and heating can be turned on in winter, which is often an open day. There is no advantage. Even if it is reheated and cold, good ventilation time and frequency should be kept In the early and middle stages, 20 minutes each time, open air conditioning and heating can also keep the indoor air fresh and clean.
2. Don't be too early or too late. In the early morning, the sun has not yet risen completely, and plants have not yet fully carried out photosynthesis. At midnight, the outdoor fresh air has been used up. The outdoor air condition at both time points is not ideal, so it is not suitable to ventilate too early or too late.
3. Don't open the window in rainy or haze days. First of all, the air flow is not good in rainy days, and the pollutants in the windows cannot be discharged. On the contrary, some of the pollution in the outdoor air will be brought by rainwater together because of the condensation of water vapor.
4. Be sure to open the window when cooking. This is a very critical issue, because when cooking is a very serious air pollution in our daily life, we have to open the window. Of course, many families will install an exhaust fan in the kitchen now, which is a very smart way to do when wasting time.
5. Strengthen convection. The effect of indoor ventilation depends on the air flow is good. When we ventilate, we not only need to open the windows and the doors of the room are open, so the effect of strengthening convection is better, but also can open several fans to strengthen the flow. The effect of removing formaldehyde and other indoor air pollutants will be more obvious.
