Poor air quality: 

The most dangerous particles in the air are invisible to the naked eye, which is why many people do not care about the health risks associated with air pollution because it is invisible. You will not eat decaying food, nor drink dirty water, because you know it is harmful to you, so why be content with dirty air？

Pollution and particles:

The World Health Organization points out that about 7 million people worldwide die each year from exposure to fine particulate pollutants in the air. Ninety percent of people breathe polluted air and are exposed to dangerous air pollution that can cause chronic respiratory diseases such as cancer, cardiovascular disease, lung cancer, and asthma.

Inhalation of allergens:

The spread of pollen usually means suffering for people with seasonal allergies, because pollen is often everywhere. Animal allergens can also easily spread from one environment to another, either in the air or through direct contact with animals. Wearing a mask is a non-invasive way to protect your lungs from inhalation of allergens.

Protect sensitive lungs:

bacteria can easily get into the air. When someone sneezes or coughs, tiny water droplets or mucus filled with bacteria spread into the air. Whether you take a plane, train, or simply walk, you will be exposed to various bacteria in the air. The best way to protect sensitive lungs is to first prevent the entry of fine particles.

When working outdoors:

wear effective protective masks to prevent harmful particles from entering the respiratory system, especially in dusty, moldy, polluted, post-combustion, high PM, high pollen, wildfire, volcanic particulate matter, and crowded environments If protective measures are taken, large amounts of particles and dust will be inhaled, affecting the health of the body.
