There is a lot of dust floating in the air

1. How to reduce indoor floating dust

1. Close the doors and windows during the day and open them at night! Avoid opening windows in windy weather and dusty weather in spring.

2. Slap yourself before entering the house. Dust is coming into the house! You'd better take off your shoes outside and bring them home!

3. Dust regularly! Remember that the dust generated on the bed is the most, and mixed with this kind of cotton wool, it is easy to become a dusty substance!

4. Reducing window opening is the best way to reduce indoor dust. If you are worried about the deterioration of indoor air quality, you can install a fresh air system, such as Haoting Fresh Air, which can be purified by a filter screen, greatly reducing the dust entering the room.

second, whether the floor is high and dusty or low and dusty

The higher the floor is from the ground, the cleaner the air is. Gaseous pollutants such as sulfur dioxide, nitrogen oxides, carbon monoxide, and well-known particulate pollutants such as PM2.5 and PM1 will decrease with the increase of floor height. If the house is close to shopping malls, downtown areas, roadside barbecues, restaurants and other places, the air quality is relatively good if you live in a high-rise building.

3. How long does it take for indoor ventilation?

If the temperature difference between indoor and outdoor is 15℃, the window opening time will take 11 minutes; If the temperature difference cannot be accurately grasped, it is enough to open the window for 3 minutes. The best window opening time is 9: -11: am or 2: -4: pm. Because the temperature has risen during these two periods, the harmful gases deposited in the bottom of the atmosphere have dispersed, and the effect of opening the window for ventilation is better. Of course, the wind speed should not be too fast when opening the window for ventilation, and it should not exceed .15m/s.. From the sense, at such a wind speed, the human body will not feel the air flowing obviously.
