I would like to use an air purifier in my office, how do I decide which one is best for my needs?

Check this website for a list of air purifiers that have passed the test for a certified clean air delivery rate (CADR): www.aham.org and click on the link for ‘consumers’.  You can use the calculator on the left to find out what size is appropriate for your room’s size. The CADR rating is only for removing particles such as cigarette smoke, pollen, dust, mold spores from the air. If you are unsure whether you need to remove particles or odor causing vapors from your work space, contact Sarah Owen at 231-4034 or sowen@vt.edu for an IAQ consult.
