Sewman, if you are looking for an air purifier, look no futher. I own an environmental company and our air purifiers is my specialty. What issues do you want to take care of (allergies, smoke, odors, pet dander, dust, mold, mildew)? Our units are about the size of a shoe box and will take care of all those issues. We use a filterless technology that is scientifically proven to reduce 99% of those and other air born allergiens. We even offer a 30 day free trial for you to experience our technology in your home. As for an IQ purifier, can't help you there pal...Let me know if you are interested and we can make arrangements for you to evaluate "fresh air" in your home.
