You can. A blower that is rated for the square footage of your dwelling (CFM rating) will be installed with the whole house system, which I recommended over the room filter. I found a contractor on servicemagic.com in my area, but you should look at multiple sources and verify contractors background and references.
Not enough info for a complete answer, but will give you something to chew on.
If you are just wanting to cut down on dust and odors, and you don't have many rooms the Sharper image system works great. While the up front cost can hurt a bit, the do offer deep discounts if you buy more than one at a time.
Pros, cheap to use, no filters to buy, doesn't make a sound and best of all nothing to install. If you ever decide to move you can take them with you. I have one in every room and love them.
