"Friends circle blue sky" schedule to extend the empty net is still useful?

The weather has improved, the smog has gradually dispersed, and the air purifier industry that relies on the weather has entered the era of “post-smog”.

Since the winter, many friends in the north have felt the difference in air quality this winter. In the past years, every winter and heating began, the “smog days” that followed would last for several days or even weeks, but this year, there has not been a real “smog day” in Beijing. The general public expressed their joy to the sudden good weather. The circle of friends has become the daily routine of the public, but at the same time, everyone is worried about whether this good weather will last for a long time.

According to the "Beijing-Tianjin-Hebei and surrounding areas in the autumn and winter of 2017-2018 air pollution comprehensive management action plan" requirements, before the end of October this year, "2+26" cities need to fully complete the "gas to replace coal", "electricity to replace coal "The mission to achieve the goal of "dissolving coal loose" over 3 million households. Insiders pointed out that the promotion of the "coal to clean energy" policy is the key reason for the extension of the blue sky "schedule period" in the Beijing-Tianjin-Hebei region.

In the future, with more relevant policies, “smog days” will be even less.

Since the "smog days" continue to decrease, will some household appliances related to smog be affected? For example, the "super net red" air purifiers in recent years. The role of air purifiers in the eyes of most Chinese people is to treat smog "private doctors". In the face of increasingly good weather conditions, will future air purifiers be used?

"Blue sky" is equal to

"Is the air quality good?"

In the eyes of most consumers, whether “air quality is good or bad” and “whether the air purifier will be used” is positively related. First, to verify a problem, “blue sky” is equal to “good air quality”? According to the monitoring data, this is not the case! Refer to "Green Breathing" (the data comes from the automatic monitoring of air quality at the national air quality automatic monitoring point of the Ministry of Environmental Protection, all data are updated in real time) nearly 30 days in Beijing (November 18) From January to December 17th, the Air Quality Index (AQI) has a minimum of 23 and a maximum of 193. Among them, the Chinese standard defines AQI as “light pollution” within the range of “75~115”, so the number of days of “light pollution” in the past 30 days can be calculated as 4 days.

The above situation is based on Chinese standards, so the number of days of pollution is only 4 days. If you look at the more stringent US standards, the situation is very different! After a rough conversion, the US standard defines AQI to be less than 50, which is mild pollution. If this is calculated, November 18~December 17 Beijing The number of days above the light pollution is 15 days (including 4 days of moderate pollution). Therefore, based on the above data, although the past time has been “the sky above the sky”, the air quality is still not optimistic!

air purifier

Is it only useful for smog?

Chinese consumers are beginning to pay attention to air purifiers, starting with the ability to remove smog (exactly removing PM2.5), so consumers generally believe that without smog, air purifiers will be useless. But the truth is not the case. The air purifier is a completely imported product. There is no fog in the world, so the idea that the 'air purifier is mainly used to deal with smog' is untenable. In foreign countries, more functions undertaken by air purifiers are 'humidification', 'except allergens', 'net ion group sterilization', 'deodorization' and so on. ”

"The air purifier has a bigger role to prevent viral flu. Although the air purifier can not directly kill the virus, the air purifier can absorb particulate matter, and the virus is attached to the particulate matter, so the air purifier While filtering the particulate matter, the virus is also adsorbed on the HEPA filter. The virus loses its activity when it is not hosted for a long time, so that the amount of virus in the air is reduced, which reduces the risk of respiratory infections."

Air pollution

Not only smog

When the CCTV host Chai Jing’s documentary “Under the Dome” made the public realize the seriousness of the smog, it also weakened the “existence” of traditional air pollutants, such as the exhaust of cars that are continuously discharged into the air. Formaldehyde, toluene, TVOC, which are volatilized during decoration, as well as odors and second-hand smoke emitted from household garbage.

In addition to air pollution such as PM2.5, indoor TVOC, pets and various life odors, spring and summer pollen and catkins are also sources of air pollution that cannot be ignored in daily life. As people pay more and more attention to the quality of life, air purifiers will become the just-needed for every family. "In recent days, although the air quality environment in the Beijing-Tianjin-Hebei region has improved, but with the resumption of work after the winter, the major projects may be repeated, and everyone should pay attention to the air quality situation in real time.

Although the air pollution encountered in life is diverse, air purifiers can effectively solve these problems. The GB/T18801-2015 Air Purifier has specified the CADR (clean air volume) and CCM (cumulative purification amount) of gaseous pollutants, and gives a clear classification. Experts recommend consumers to recommend according to the new national standard. “Three high and one low” (high CADR, high CCM, high energy efficiency grade, low noise) principle to purchase products, and try to buy higher grade products, so as to effectively filter most of the air pollutants in life.
