EverGreen offers high quality respirators at reasonable price for our customers.
To prevent respiratory disease, we recommend wearing approved sanitary-aid Health Care Respirator that can filter fine particles, such as yellow dust.
Korea’s sky often suffers from fine dust from China, with the influx of Chinese smog. The troublesome yellow dust is seasonal, but the fine dust is regarded as a serious pollutant from fossil fuels or automobile fumes.
EverGreen provides a defense against these problems.
