Brand new, purchased less than a month ago from a US authorized IQAir dealer, this still in the box Healthpro Plus 250 is for sale. I had it shipped over when my company had plans to send me to a satalite office outside of Beijing and thought I'd need it for a studio apartment. As the plans have changed to keep me in Beijing, i no longer need it so I am selling it at my cost to buy it and ship it over.
