How to Portect Yourself from Unhealthy Air when travelling in Beijing

When the air polluted days do occur unluckily during your travelling in Beijing, the following tips might be useful for protecting yourself in advance.

Monitor the AQI in your area in advance: If the AQI is below 100 (Green or Yellow), it is ok to do the outdoor activities such as hiking on the Great Wall; If the AQI is over 100 but under 150, going to visit the opening space such as Tiananmen Square and The Temple of Heaven within certain hours except for the evening, is also ok for most of the insensitive groups; If the AQI is over 150 which rarely happened since 2017, you'd better stay at home or do some indoor activities such as exploring the local cuisine in the restaurant of Beijing.

Bring a Mask: The only mask recommended is the N95- or N100-rated mask, which can prevent over 95% PM 2.5 particles from being inhaled by you. You can buy them at a pharmacy or hardware store in the case of the terrible air quality.

Walk, don't run: When you have to go out and face the bad air outside, make sure that you wear a proper mask and you will not rush but slow down your pace to breathe less impure air.
