Kangfeng first raised the highest indoor air environment standard, and the "Belt and Road" model project perfectly met the standard

Recently, the first sample case of the world's highest indoor air environment standard proposed by Kangfeng Environment-the Belt and Road Environmental Technology Exchange and Transfer Center (Shenzhen), the first third-party inspection meets the design requirements, which means " The problem of cross-infection in the offices of the Belt and Road Initiative has been solved in a sense, and it also marks that Kangfeng's micro-environment air purification and disinfection technology has reached the world's latest height.


It is reported that the Belt and Road Environmental Technology Exchange and Transfer Center (Shenzhen) aims to promote the international environmental protection cooperation between my country and countries along the “Belt and Road”, drive the accumulation of advantageous resources in the environmental protection industry at home and abroad, explore innovative modes of international environmental technology exchange and transfer, and create environmental protection technologies Innovate in Silicon Valley and industrial highlands, build a pioneering demonstration of high-quality construction and development of ecological civilization, and effectively support the construction of the green "Belt and Road". It is another national platform for Tianan Cloud Valley to settle down after the national human resource service industrial park.

  This time, from the perspective of public health and technical feasibility, Kangfeng Environment proposed for the first time three new indicators of the world's first indoor air environment standard:


    1. Formaldehyde ≤ 0.03mg/m³ 

The Chinese health standard "Hygienic Standards for Air in Room Air" stipulates that the maximum concentration of formaldehyde in room air is 0.08mg/m³. After being purified by Kangfeng Clean Alkali Technology, the content of air pollutants in the air can be controlled at 0.03mg. /m3 3 years old, please contact me.

    2. Particulate matter PM2.5 ≤ 15ug/m³ 

PM2.5 refers to the particles in the ambient air with a diameter less than or equal to 2.5 microns. The World Health Organization (WHO) believes that PM2.5 is less than 10ug/m 3 as a safe value; but for developing countries, this standard can be improved. The average PM2.5 in cities in China is around 70ug/m 3 . The best value of the quality standard is 35ug/m 3 . Purified by Kangfeng solid alkali technology, the PM2.5 content in indoor air will not exceed 15ug/m 3 , the air will be cleaner and breathing will be more free .

3.The fine bacteria ≤ 4cfu / 30min · φ90 dish (150cfu / m³).

my country’s air colony quality standard is 2500cfu/m3. Taking the hospital sanitation standard as an example, the colony concentration of the hospital’s general operating room, general protective isolation room, intensive care unit, etc. shall not be higher than 200cfu/m3, which shows that when the environment is When the colony concentration is less than 200cfu/m3, patients with very low immunity are safe in this environment. The new coronavirus can be spread through the air. Under the same environment, the higher the amount of viruses and harmful bacteria in the air, the more likely we are to be infected or get sick. After the installation of Kangfeng solid alkali purifier, the concentration of colony in the environment can reach below 150cfu/m3, reaching the standard of hospital intensive care unit. It can effectively isolate the spread of the virus in the air and protect the safety of our family.

my country's air quality standards

After Kangfeng equipment is purified


≤0.1mg/m 3

≤0.03mg/m 3

Particulate matter PM2.5

≤75ug/m 3

≤15ug/m 3


≤2500cfu/m 3

≤150cfu/m 3


It is much higher than the standard proposed by my country's "Indoor Air Quality Standard" GB/T 1 8 8 3-2 0 0 2. We plan to take the highest standard of the Nordic indoor environment as our goal to remove pathogenic microorganisms and formaldehyde in the air. Gaseous pollutants solve the cross-infection of respiratory infectious diseases in the public office environment, and make the Belt and Road Environmental Technology Exchange and Transfer Center (Shenzhen) the first "respiratory health and safety demonstration base" in the country.

This project adopts the indoor air quality standard of North Europe, to removal the aerosol of the air and solve the respiratory infection problem at public offices, to make this centre as the sample area for health respiratory in the cuntry.

The air quality goal is reached: formaldehyde≤0.03mg/m3, particulate matter PM2.5≤1ug/m3, bacteria≤4cfu/30min·φ90 (150cfum3)
Remarks: In the sanitation "Standard Quality of Indoor Air" GB/T 18883-2002, formaldehyde ≤0.1mg/m3, total number of colonies ≤2500cfu/m3.

"Ambient Air Quality Standard" GB 3095-2012 PM2.5 standard office area daily average is ≤75ug/m3. Finland, which has the highest air requirements, divides indoor air quality into three grades: S1, S2, and S3. S1: 0.03mg/m3, the best indoor air quality. S2: 0.05mg/m3, good indoor air quality. S3: 0.1 mg/m3, satisfactory indoor air quality.


Kangfeng is mainly responsible for the purification of the multifunctional hall, large conference room, VIP reception room, and open office area of ​​the Belt and Road Environmental Technology Exchange and Transfer Center. The total purification area of ​​the plan is 1,260 square meters.


The air quality testing of the Belt and Road Environmental Technology Exchange and Transfer Center (Shenzhen) was performed by Shenzhen Harmony Technology Testing Co., Ltd. The data collected and recorded formaldehyde, bacteria, and PM2.5 from 16 monitoring points, all in line with the Kangfeng environment. The three new indicators of the indoor air environment standard of the company have passed the acceptance perfectly.

According to the research conclusions of the US Centers for Disease Control and Prevention, people are susceptible to infection when the number of indoor air colonies is higher than 500 cfu/m³, and it is extremely difficult to be infected when the number of indoor air colonies is lower than 180 cfu/m³. As the model project of the Belt and Road Environmental Technology Exchange and Transfer Center (Shenzhen) reached the standard, Kangfeng Environment Chairman Li Guopei pointed out: In this sense, the problem of cross-infection in the Belt and Road Office has been resolved.

In the future, Kangfeng Environment will continue to move forward, benchmarking the world's highest indoor environment standards, and continuously research and develop air purification technology to protect breathing safety, so that people under the same sky can breathe freely
