First of all, compare the air purification efficiency. Since most air purifiers in passive adsorption purification mode use a fan + filter mode to purify the air, there will inevitably be dead corners when the wind uses the air flow. Therefore, most passive air purification can only be used in air purification. A certain purification effect is produced around the place where the device is placed, and it takes a long time to filter all the indoor air, and it is difficult to produce an effect on the purification of the entire indoor environment.
Active air purification is to use the diffuse characteristics of the air to purify the air to every corner of the air purification factor, where the air can be diffused can produce a purification effect, compare the negative ion air purifier and find that after releasing negative ions in the air , Negative ions can actively attack, look for polluting particles in the air, and condense them into clusters, and actively settle them. From this point alone, active air purification has a more urgent and obvious advantage.
The second is to compare the removal effects of small particles of air pollutants. The most harmful air pollutants are fine particles with a diameter of less than 2.5 microns (that is, PM2.5, medically called lung particulate matter).
However, through experimental research, it is found that the passive purification mode is powerless for these small 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 endanger human health.
A comparison of negative ion air purifiers based on the principle of active purification for air purification found that small-sized negative ions in the air can not only easily remove large-sized particles in the air, but also for air purifiers with a diameter of less than 0.01, which is difficult in the industry. The removed particulate dust has a 100% sedimentation removal effect. Eco-grade negative ion generation technology that mimics nature has come out. It is characterized by small particle size and high activity. It achieves a better air optimization effect with its excellent diffusion and health effects.
Finally, a comparative analysis of the quality of air treatment is carried out. Studies have found that under the principle of passive air purification, if the filter aperture can be small enough, the result of air treatment can only achieve the purpose of purification, that is, only “hurry up” air can be obtained, while negative ion air purifiers are different. Effectively remove particulate pollutants in the air, decompose formaldehyde and other harmful gases, provide clean air to the indoor environment, and provide the indoor environment with negative air ions that are effective for human health care, so that the indoor air quality can reach “healthy air” standard.
