First, the air purification efficiency of the filtration process is compared. The air purifier with passive adsorption and purifying mode is mainly used for air purification by the mode of fan + mesh. Wind use of air flow will inevitably exist dead corners, so passive air purification of most of the air purifier can only be placed around to produce a certain purification effect, a long time to the indoor air filtered all over again, it is difficult for the whole indoor environment purification effect.
Active Air purification is the use of air diffuse characteristics of purification factors to reach all corners of the air purification, air can diffuse to the place can produce purification effect. The study found that under the principle of passive air purification, if its mesh aperture can be small enough for the air treatment can only achieve the purpose of purification, that is, only "clean" air, and anion air purifier is different, not only can effectively remove particulate pollutants in the air, decomposition of formaldehyde and other harmful gases, to the indoor environment to provide clean air, but also to the indoor environment to provide health care for the human body has an efficient role in the air anion, so that indoor air quality to achieve "healthy air" standards.
