I am looking at the line of Iqair Air Purifiers and would like to know where a good place to purchase one is. I am mostly looking for the lowest price, but will gladly pay a bit more for superior customer service and support. My daughter has bad allergies and we are hoping that by going to a whole house air filtering system her symptoms will improve. If anyone knows a dealer that offers operational display models or demonstrations that would be wonderful as well. We are also somewhat interested in the noise factor, no one wants to be kept awake at night by something that sounds like a jet engine taking off!
