Opening the windows for ventilation every day makes the house full of dust. How do you deal with it?

First of all, when the sky is blue and white clouds are outside, the wind and sand are relatively strong. You can open the windows on the south side but not the windows on the north side. This way, convection will not occur and dust will not be blown in. Remember it’s blue sky and white clouds. If the north wind blows, open the south one, and if the south wind blows, open the north one. Don't open it at the same time to form convection.

On hazy days, here I use non-blue sky and white clouds to replace light pollution and heavy pollution. Mild pollution is also pollution, and susceptible people must also take precautions. In non-blue sky and white cloud weather, it is best to install a fresh air system. You can choose a ceiling-mounted machine for a rough room and a wall-mounted machine after decoration.

If the bedroom window faces the road, you need to open the window every day for ventilation. However, once you open the window, there will be loud noise and dust. There is also a construction site nearby, and there are people coming and going every day. Vehicles and streets cannot avoid dust. For this reason, I have come up with several solutions. Let’s see which one is more practical!

1. Window ventilator

There is a slightly higher-end building that has just opened near our community. I accidentally found that there was a small strip of metal on their windows, so I I ran in to inspect the house and inquired about it, and then I learned that there is a window ventilator. The staff said that it is for sound insulation and ventilation. If the window ventilator is effective for a long time, I can choose to close the window to prevent dust from entering the room. I am worried. What matters is the actual effect and service life.

2. Fresh air system

The neighbor downstairs installed a central air conditioner during the renovation, and also chose to install a fresh air system. It was so foresighted. Got it! It can automatically change the air without opening the windows, and can also automatically detect the air quality and introduce fresh air. We did not consider this issue when we first renovated our home. Now that it is all completed, the subsequent installation of a fresh air system is really a big project.

3. Ultra-dense window screens

Compared with the huge fresh air system installation project, my neighbor thought of installing nest honey window screens, which is also a way. After carefully reading other people’s experiences using window screens, I found that it can indeed achieve the dust-proof level, but it may affect the ventilation effect.

4. Air purifier

The last resort is that I want ventilation but I am afraid of dust. I install an air purifier to purify the indoor air. Use a vacuum cleaner to clean the dust and let the air purifier absorb the fine particles. This way, it can be used not only in the bedroom, but also in other areas. Rooms are also available.
