The weather is bad. Can I use an air purifier at home?

Yes, the current "negative ion purification technology" has a remarkable effect on purifying three-state pollution.

The international standard ISO 16 184 clearly affirms that negative ion technology is one of the technologies to improve indoor air quality. Negative ion purification technology refers to the application of air purifier based on negative ions, which ushered in the 3.0 era of air purification. The purification effect of negative ions on air is due to the combination of negative ions with positively charged particles such as bacteria, dust and smoke in the air, and they fall into spheres to eliminate indoor pollution hazards. Negative ions can be divided into three sizes: large, medium and small. The purification effect of negative ions with small size is far better than that of negative ions with large and medium size.

Advantages:

Small particle negative ions have high activity and long natural migration distance, and can actively capture bacteria, dust, smoke and other positively charged particles in the air, so that they can coagulate and precipitate, effectively remove dust below 2.5 microns (PM2.5) in the air, and even 1 micron and 0. 1 micron particles, thus reducing the harm of PM2.5 to human health. The book "Application of Air Negative Ions in Medical Care and Environmental Protection" compiled by the expert group of China Air Negative Ions and Ozone Research Association has also mentioned many times that the ecological negative ions in the air have a sedimentation and removal effect of 100% on particles as small as 0.0 1 micron, which is difficult to remove in industry.

Small particle size negative ions can also reverse the potential polarity of cell membranes of bacteria, viruses and other microorganisms, so as to inactivate them and kill them;

Small particle size negative ions can also degrade formaldehyde. The negative ion electron beam with negative oxygen ions as the active carrier irradiates the air mixture, which can degrade formaldehyde into harmless substances such as carbon dioxide and water.

Disadvantages:

Small particle size ions have a short life in air, so they need to be released continuously to optimize the environment. There are few technologies to generate small particle size negative ions. At present, the technologies that can solve the above shortcomings mainly include ecological negative ion air purifier and nano-fullerene negative ion releaser technology using ecological negative ion generation chip technology. 40-60 million negative ions with small particle size, high concentration and long natural migration distance can be released per cubic centimeter to meet the purification needs; But also support long-term boot use.

The above air purification technology is the most commonly used technology for air purifiers at present, and ecological negative ion air purification is a more effective way to remove indoor pollutants, which has opened the 3.0 era of purifier technology.
