Ionic Pro COMPACT Air Purifier

We purchased the full size tower for our family room due to my daughters allergies that worked great. I was amazed with the results in the amount of pollutants that were on the filter. We decided to buy a smaller version for our office which is a smaller space. My daughter is in there only for short periods of time to use the computer. I have to admit this unit is not as effective as the full size towers by a long shot. It is very quiet, It has to be cleaned a lot more frequently that the larger unit. The big problem is that the fan ducts get a lot of dust caked in them, so I have to actually dust the machine as well.The price was very reasonable, but you pay for what you get. If I could do it all over again, I would spend the extra money for the Ionic Pro tower. It works better, The filter is bigger and better.The unit has proven effectiveness in our household. I would not recommend this unit. I do highly recommend the Ionic Pro tall tower. I wrote a review on this product so if you are in the market for a purifier please read that review, I know it will be helpful.
