Sales of dust masks and air purifiers have spiked this week as serious fine dust has blanketed the Korean Peninsula for several days.
 
Gmarket, one of the country’s largest e-commerce sites, said Thursday that mask sales picked up on Monday following a significant increase in the concentration of fine dust.
 
The company sold more than twice the number of masks between Monday and Wednesday than the same three-day period last week.
 
Mask sales particularly jumped in Seoul, up four-point-six times compared with last week. 
 
Sales of air purifiers on GMarket also shot up 36 percent from last week on Monday to Wednesday, with sales nearly tripling in Seoul, Incheon and Gwangju.
