  A couple years ago, the Beijing US embassy’s air quality monitor, who independently monitors PM2.5 concentrations and publishes them on Twitter, described the air pollution as “crazy bad” – for lack of a better word. Although the term “crazy bad” was quickly replaced by “beyond index”, the terminology seriously hurt the feelings of Chinese people and netizens named the monitor the “beyond description machine” .


PM2.5 particles damage the respiratory and cardiovascular systems: symptoms and consequences include respiratory irritation, coughing, dyspnea, reduced long function and increased asthma. Hazardous pollution can lead to chronic bronchitis, arrhythmia, heart diseases and cardiopulmonary diseases – which can lead to premature death.

  According to the United States Environmental Protection Agency, when the air quality index is above 200 everyone should avoid all outdoor physical activity.


  If you live in Beijing, you are most certainly not a stranger to this type of news ---- But heavy smog keeps on striking.

  The Chinese Ministry of Environmental Protection’s latest monitoring data shows that Beijing, Tianjin, Hebei and 49 cities in their surrounding areas are suffering from serious pollution – 16 of these cities are suffering from extreme pollution. Continuously this winter, in Beijing, Tianjin, Hebei and their surrounding areas, 62 cities have been in pollution yellow alert – and above.

Countless people are asking: 
How to live well in Beijing?
Which district in Beijing has the best air quality?
The Spring festival is coming: Where should I go to hide from pollution?

Regretfully, “when the nest overturns, no egg remains intact”. According to China’s Air Quality Index, the whole north of the country is submerged in smog. 

  Where do you have to go to get a breath of fresh air?  

  The year is 2017 and all of the North of China is submerged. Only one small room still holds out against the pollution invasion. 



Look at the PM index – Want to come try out the air?
Here comes the advertisement: “no matter how the world changes, we are still clean as ever!” – in Sanfine International Hospital’s ultraclean class 1000 laminar airflow operating room

But what is a class 1000 laminar airflow operating room?


  During the second half of the 19th century, the frequent occurrence of wound infections brought a great number of complications during surgical procedures. They turned initially successful operations into catastrophes. Even if the invention of antibiotics saved thousands of lives, wound infection continued to be a huge problem especially in military field hospitals where operating conditions are poor and wound infections more frequent. To solve this issue, famous British surgeon Joseph Lister, introduced the antisepsis system to hospitals, which greatly increased post-surgery survival rates and shortened patients’ recovery times.

  To further reduce infection rates, steam sterilizers, rubber gloves ect started being used for surgical operations. From then on, the operating room went from the antiseptic age to the aseptic age. 

  With the development of medical science, the operating room needed to evolve even more. Reconstructive burn surgeries, brain surgeries, eye surgeries, lung surgeries, mediastinal surgeries and other types of difficult surgeries must be carried out in ultraclean operating rooms to reduce as much as possible infection rates as well as ensure success of the operation. That is why the advent of the laminar flow operating room was revolutionary – its introduction allowed surgical operation success rates to increase even more.

  Laminar flow operating room is a multi-functional measure whose purpose is to efficiently filter dust particles and bacteria in the air in order to prevent infections. At the same time, the laminar flow operating room provides an environment with appropriate temperatures and humidity as to reduce the risk of tissue injury during the operation.
Laminar flow operating rooms are divided in the following categories according to the amount of airborne particles (≥ 0.5µm in diameter) per cubic foot. 

Class 100 (super clean):  cardiac surgery, arthroplasty, kidney transplant 
Class 1000 (standard clean):  plastic surgery, orthopedics 
Class 10000 (ordinary clean): E.N.T, dentistry, gynecology
Class 100000 (ordinary clean): outpatient, emergency treatment, infection operation

Air cleanliness in the Class 1000 laminar flow operating room reaches up to 99.98%. The temperature and humidity of the room remain constant, but the air is changed 600 times in one hour. 


• Purification and sterilization of the room to obtain an air cleanliness of 99.98%
• Laminar airflow operating room pressure (+23-25Pa), infection rates close to 0%
• Comfortable airflow (room temperature can be adjusted to 15-25 degrees and humidity to 50-65%)
• The unique designs of laminar airflow operating rooms means bacteria has no place to hide

My office vs the operating room – Want a taste of this delicious air?


Well unfortunately, you can’t. Hospital regulations stipulate non-surgical personal cannot enter without permission. 

With no better alternatives, let’s take a look at some professional tips protect ourselves inside the unavoidable “airpocalypse”.

 Don’t forget to wear a mask when going outside: ordinary masks do not filter PM2.5 particles, cotton masks are not very efficient, it is best to wear masks that specialize in filtering these particles. 

 Avoid wearing eye contact lenses: smog means lower atmospheric pressure which can lead to corneal hypoxia and dry eyes. The micro-contaminants in the air can cause eye irritation, leading to discomfort.


 Don’t open the windows on extremely polluted days: the pollution outside will only make the pollution inside worse. Cherish every inch of indoor air and try your best to breathe next to the air purifier!

 Decrease the amount of outside physical exertion:  try not to stay outdoors at all – if you have to, once again, don’t forget your mask.


 Wash your hands and face when you get home: pollution particles stick to people’s skin, clean them off as soon as possible when you get home.


 Drink plenty of water: drinking more water allows secreted immunoglobulin A and mucus and cilia in the lungs to become more robust, enhancing the body’s ability to resist the smog!


 Wash your clothes more often:  clothes are often contaminated with dust and other particles – clean them as frequently as possible to avoid propagating bacteria and viruses. 


 Look after your lungs: have a steamed pear with rock sugar with some lily – a Chinese favorite. Lily and pears relieve from coughs, moisten the lungs and are generally good for the respiratory system. Not only do they protect the lungs, they also accelerate the discharge of body toxins.
