The increase of pm 2.5 is the main cause of haze weather.

In foggy days, aerosols in the atmosphere make the air turbid and polluted, and it is not easy to be discharged after entering the human body. Staying in alveoli will cause harm. Long-term inhalation can easily cause rhinitis, bronchitis and other diseases. Let Puweixin, who is aiming at the sky, help you protect PM2.5. American science and technology and related research surveys show that almost 50% of PM2.5 inhaled is deposited in the lungs. With the increase of PM2.5 concentration, people's risk of respiratory and cardiovascular diseases will increase accordingly. Therefore, we should not take the smog weather lightly. We should protect ourselves and our families before the air improves.
