Various forms of pollution have increased as
China has quickly industrialized. Air pollution has become one of
the biggest issue for many foreigners and Chinese people. Dust,
chemicals, fine particulate matter (PM), ozone and secondary pollutants are the
main emissions. The PM 10 and PM 2.5 are associated with number of
symptoms and chronic illnesses of the respiratory,
cardiovascular and immune systems. It is then no wonder that you’re considering
a pollution mask to protect yourself.
Unfortunately, it can be a bit confusing
because there are so many different masks, brands and certifications out there. MSH China
decided to investigate: we asked specialist to help us answer the question “how to
choose the right anti-pollution mask?”
1. N95 - N99
First thing important to check for when
you’re choosing a pollution mask is to see the mention N95 or N99. These
numbers refer to their filter able to block 95% or 99% of air
pollutants. You can also adopt KN95, FFP2. Usually all these types of
masks will have work safety certifications.
2. AQblue
Based in Beijing, AQblue started to
sell high quality anti-pollution masks after
the 2013 Airpocalypse crisis. They developed their own respirator (mask) and
meet United States N95 filtration standards. Comfortable and effective
for prolonged hours, you can buy it on WeChat and
also Taobao.

3. Reusable Masks
Some brands are specialized in reusable
masks. They can be used many times and cleaned with a wet cloth. It is
important to clean and store it properly otherwise the mask itself can become
infected with pathogens especially after cleaning with a moist cloth.
Can last about six months.
4. 3M
The 3M 95N is particularly popular in
China. Effective and cheap however this model is less
comfortable to wear especially for prolonged hours. Must be replaced after a
single use.
5. Fitting
According to Jeffrey Bauer, co-founder
of AQblue, after selecting the right mask, fitting is one of the most
important thing you should look for in a mask. A mask should be tight fitting
enough to create a pressurized seal around your face, no gaps
to let outside air in. AQblue masks offer multiple sizes for adults and
children.
6. Ventilation
Ventilation is another important point when
you’re choosing a mask. Especially if you are using it while doing sport. A good
mask will not allow moisture and fogging near the nose-bridge and eyes. Select
one mask with a CO2 outlet that will allow the CO2 to leave the mask.
7. International Standards
