What are the misunderstandings in using indoor air purifiers in Chongqing?

1. Wait until the fog is open

Some consumers mistakenly think that the purifier only needs to be used for one or two hours in the fog. In fact, in addition to particulate matter in the air, harmful gases such as pathogenic bacteria and formaldehyde are also air pollutants that endanger human health. Therefore, the air purifier needs to be turned on for a long time to be effective and cannot be used as a temporary household appliance.

2. Only one air purifier is used for large-sized households

Generally, the applicable area of different types of air purifiers is clearly marked in the specifications. Generally, one purifier can control the air quality of a room, and it is enough for small-sized families to buy a large-sized one. For large-sized families, it is necessary to equip multiple purifiers at the same time to ensure the air quality of the whole family.

3. Only pay attention to whether PM2.5 meets the standard

The popularity of the purifier market comes from the smog weather. Some brands claim that PM2.5 has a "removal rate" of more than 9%, but the actual effect lacks third-party verification. Moreover, the removal of PM2.5 does not mean that the air reaches the standard. In addition to inhalable particulate matter, there are pathogenic bacteria and harmful gases in the air, and the purification capacity of the purifier needs to be comprehensively measured.

4. As long as there is no odor in the room

Indoor air standard is a comprehensive measure of inhalable particulate matter, harmful gases, odor and bacteria and viruses, and it is unreasonable to determine air quality only by odor. In addition to PM2.5 and odor that can be felt on the surface, formaldehyde, benzene, radioactive radon, etc. will all cause harm to the body.

the above is the misunderstanding of indoor air purifier, which is an essential purification equipment for every family.

The book "Environment, Health and Negative Oxygen Ions" edited by Lin Jinming, an expert of Chinese Academy of Sciences and a doctoral supervisor and professor in Tsinghua University, has repeatedly said that when the concentration of negative ions in indoor air reaches 2, per cubic centimeter, the amount of floating dust in the air will be reduced by more than 98%. It has an excellent effect on PM2.5, a particulate matter that can enter the lungs. Therefore, in the air containing high concentration of small particle size negative ions, the most harmful dust, bacteria, viruses and so on below 1 micron in diameter in PM2.5 are almost zero.

Eco-level negative ion technology generates eco-level negative oxygen ions through cutting-edge technologies such as Negative ion converter technology, nano-fuiierene negative ion release technology and eco-negative ion generation chip technology. Ecological-grade negative oxygen ions have small particle size, high activity and long migration distance. They can actively capture pollutants such as dust, particles and even pm2.5 in the air, kill bacteria and viruses, and adopt advanced pollutant collection technology to efficiently collect pollutants in the air to avoid secondary pollution. The removal rate of pollutants such as formaldehyde is over 99%, which is the safest and most effective air purification method at present.
