Made in America. Sold in China.

China's air pollution is a serious health hazard, especially in major cities. While many Chinese consumers wear anti-smog masks when they venture out, home air purifiers are becoming increasingly popular.

"The market has really heated up in the last two years," said Peter Mann, founder and CEO of Oransi, which manufactures air purifiers in the United States.

After several visits to China, the Austin, Texas-based firm developed a line of high-end purifiers -- costing $2,000 to $3,000 each -- specifically for sale there.

Mann shipped the first container of 500 purifiers in November -- which sold out quickly -- and expects to ship 1,000 next month.

Mann said his entry into China could help double his company's revenue from $3 million in 2013 to $6 million this year. Thinking ahead, he's already keen to develop a line of less expensive purifiers to sell in China.
