Can an air purifier remove smog?mini humidifier manufacturer

　　At present, the air purification products on the market can be basically divided into two categories. One category relies on a variety of adsorption filter materials, such as filters, activated carbon, and photocatalysts to absorb harmful substances in passive purification. Another type of negative ion technology is used to actively purify pollutants in the air. Different product types have different functions, so they cannot be generalized. Smog is a general expression of the excessive content of various suspended particulate matter in the atmosphere. Sulfur dioxide, nitrogen oxides and inhalable particulate matter are the main components of haze. The first two are gaseous pollutants, and the last particulate matter is the aggravated fog. The main culprit of haze pollution. With the deterioration of air quality, the phenomenon of haze weather has increased and the damage has increased. Many regions in China incorporate haze weather phenomena into fog as early warning and forecasts of severe weather. Collectively referred to as "smoggy weather." Therefore, air purifiers must not only remove particulate pollutants, but also purify sulfur dioxide, nitrogen oxides and other pollutants. Different air purifiers have different haze removal effects.

　　The filter type air purifier uses a fan to draw air into the machine, and filters the air through a built-in filter, which can mainly filter dust, odor, and disinfect. This kind of filter type air purifier mostly uses filter + activated carbon filter + other filters to process the air. Among them, the filter screen has the function of filtering dust particles, and other activated carbons mainly absorb peculiar smell, which has a better purification effect on larger particles, but has a poor purification effect on ultrafine particles and gas pollutants.

　　Active purification technology mainly uses negative oxygen ions as purification factors for air purification. The purification effect of negative ions on the air is derived from the combination of negative ions with bacteria, dust, smoke and other positively charged particles in the air, and they gather into balls and fall to eliminate PM2.5 hazards. Experiments have shown that the smaller the diameter of the floating dust, the easier it is. Precipitated by negative ions. Moreover, negative ions have a high-efficiency degradation effect on toxic and harmful gases. The common toxic and harmful chemical gases in indoor air can be broken down into carbon dioxide and water by opening chemical molecular bonds by negative oxygen ions; it also has a decomposing effect on hydrogen sulfide and ammonia, and has no effect. Any side effects, there is a good effect of removing haze.
