100% Worth the Purchase Price
I bought the large air purifier and two of wall plug versions in 2007, and they're still running strong.<br /><br />  I'm an elementary teacher and am constantly surrounded by a multitude of germs.  In an effort to preserve my health, I decided to give these a try.  The large unit lives in my classroom and runs 24/7 all school year long, and it definitely helps!  (Healthier teacher, healthier students, everyone is happy).  The two small units are plugged in my bathroom and bedroom.  I live in the Bay Area, where mold is a problem, but I have yet to see (or smell) any in my home.  In my opinion, you quickly become accustomed to the noise.  Plus, I only have to change the bulbs about once every six months.  Germ Guardian rocks!<br /><br />PS:  When I got married a year ago my husband asked what those "things" were and if they had to be on all the time.  After catching a massive bug from my students he insists that I keep them running, and we've enjoyed perfect health since.
