Now many people use air purifiers at home, so are air purifiers actually useful? Air purifiers can purify indoor air. They can absorb some fine substances and dust in the air, filter these substances, and release clean air. How is the purification effect of air purifiers? The following is a detailed introduction to the purification effect of air purifiers.
1. High air purification efficiency. Most air purifiers with passive adsorption purification mode use the fan + filter mode for air purification. The wind uses the flow of air and it is inevitable that there are dead corners.
Therefore, passive air purification can only produce purification effects around the air purifier. It takes a long time to filter all the indoor air, and it is difficult to produce effects on the purification of the entire indoor environment.
2. Active air purification uses the diffuse characteristics of air to bring purification factors to every corner for air purification. Wherever the air can diffuse, it can produce purification effects. Comparison of negative ion air purifiers found that after releasing negative ions in the air, negative ions can take the initiative to attack, find polluted particles in the air, condense with them, and actively settle them. From this point alone, active air purification has a relatively obvious advantage.
3. Secondly, the removal effect of small-particle air pollutants is compared. Among air pollutants, the most harmful to humans are fine particles with a diameter of less than 2.5 microns (i.e. PM2.5, medically called respirable particles). Experimental studies have found that the passive purification mode is powerless for these fine particles such as PM2.5. Small particles such as PM2.5 can easily pass through filters, activated carbon and other substances, and re-enter the air to harm human health.
4. By comparing the negative ion air purifier based on the active purification principle, it is found that the small-particle negative ions in the air can not only easily remove large-particle particles in the air, but also have a 100% sedimentation removal effect for the fine dust with a diameter of less than 0.01 and difficult to remove in industry. The ecological-level negative ion generation technology that imitates nature has been introduced. It is characterized by small particle size and high activity, and achieves better air optimization effect with its excellent diffusion effect and health care effect.
Air purifiers are generally useful, but they are not so practical in some environments with good air quality. Air purifiers can be used in environments with a lot of pollutants to purify impurities and toxic and harmful gases in the air. In some cities with serious air pollution, air purifiers can be used indoors to purify the air. You can buy according to different functions.
