Somewhat of a strange question but it's related to this forum. I'm setting up my new iMac in my living room as opposed to my office as I'm trying to spend less time back in my cave/office. We have a boxer, which I would love to get rid of, but my wife and children out ruled me. The dog is not allowed in my office which solves the pet hair problem but because the iMac will be in the living room, I was wondering if anyone could make a suggestion on a good air purifier for pet hair and dust. I want to keep that garbage out of the computer. I've been wanting one anyways as it compiles on my xbox, dvr, ps3, tv, etc. The living room is pretty big with very tall ceilings if these things are rated by size. Thanks for the help.
