respirator |
We have to breathe in smog when doing exercise outdoor in sunny mornings, as smog contains harmful materials, such as Sulfur dioxide and nitrogen dioxide and PM2.5. Experts remind us that heavy smog easily provoke respiratory track and probably result in asthma or bronchitis. Then what measures can we take to deal with dust and smog? The most direct way is to put on protective respirator.
We should reduce outdoor activities in smoggy days. Common masks can prevent catkin and dust well, but they can’t supply good protection in PM2.5. People who work in open air need professional protective respirators to avoid harmful particles in air.
Compared with common masks, high-level face masks are more expensive. But they bring remarkable effects in all kinds of pollutants and pollen. Customers should notice the type of respirators when choosing them. We need to keep it in mind as health is our own thing. While avoiding smog with mask, we also should do something for environment protection.
