Air Purifier San Francisco

According to IQAir's latest air quality report, San Francisco's air quality is rated as good, which has an important relationship with the proximity of the city.

San Francisco’s air pollution mainly comes from transportation emissions, that is, vehicles such as cars, motorcycles and trucks, as well as airplanes and ships, all of which cause air pollution to the surrounding environment. 1 It has become more and more common in the Gulf region, leading to a sharp increase in air pollution, which usually occurs in summer and autumn.

Regardless of the impact of potential wildfires, winter pollution is usually much more serious than summer, which is usually caused by increased heating and wood burning. In addition, cold weather conditions may affect the behavior of air pollution particles. In cold conditions, the opposite is usually the case, and a layer of warmer air is usually maintained above the cooler ground air. This reversal is called thermal reversal and causes a layer of warm air to work like a"hat"or"lid", keeping the air underneath for a long time, usually until the wind and other weather changes dissipate it. Therefore, in winter, these inversions will extend and exacerbate existing air pollution and smog in San Francisco and the Bay Area.

In the past three years, California’s five most destructive wildfires were relatively close to San Francisco, greatly affecting the air quality of the entire Bay Area. 2 In November 2018, the camp fire destroyed 153,336 acres of land and drove San Francisco’s Air Quality Index (AQI) to 137 months, making it “unhealthy for healthy people”. Concern for people suffering from respiratory diseases. Other cities in the Bay Area (such as San Jose and Oakland) have seen similar increases in air pollution levels.
