Query: Returned it without opening

After doing much research and comparing quality/efficiency/cost I decided on the Blueair line of purifiers. I contacted the company to find out where the 250E was manufactured. I was told that it was manufactured in Sweden/Germany/Texas USA.When the purifier arrived, I noticed, prominently printed on the box, MADE IN CHINA. I returned it without opening it. I can not justify owning a heath product manufactured in a country that allows the use of lead and other poisonous material in manufacturing.
