Causes and improvement strategies of haze weather in China

When the suspended water vapor in the atmosphere condenses and the visibility is lower than 1000 meters, it is called fog in meteorology. When the water vapor contained in the air reaches the maximum, saturation will occur. If the water vapor exceeds saturation, the excess will condense out and combine with tiny dust particles in the air to form small water droplets or ice crystals, which will be suspended in the air layer near the ground and become fog. The lower the temperature, the less water vapor can be contained in the air, and the easier it is to form smog.

You can choose to arrange MIA fresh air system for your home. It uses the function of ventilation to continuously discharge indoor dirty gas containing formaldehyde outside, and at the same time send outdoor fresh air purified by machines indoors to ensure the freshness and cleanliness of indoor air.
