How does this air purifier purify the air? The EPA laboratory research of the US Environmental Protection Agency found that there are three main methods of removing dust for air purification (dust removal): 1) Brownian Diffusion-the smaller the particles, the stronger the effect. 2) Interception - The larger the particles, the better the effect. 3) Negative oxygen ion neutralization (ion Neutralization)-the smaller the particles, the better the effect. Negative ions can take the initiative to capture small particles, make them agglomerate and precipitate, effectively remove particles 2.5 microns (PM2.5) and below, and even particles of 1 micron in the air, thereby reducing PM2.5 to the human body Health hazards. The purification effect of negative ions on the air is derived from the combination of negative ions and positively charged particles such as dust, smoke and so on in the air, and they gather into balls and fall to eliminate PM2.5 hazards.
