Ionic Pro Air Purifier - Full Size Review

As other people have noted this machine must be cleaned once a week or so.  That is not a big deal to me.  It cost almost nothing to run, its very efficient.  It's also quiet to the point of being free of any sound at all. 

Most importantly, of course, it gets the job done.  It has to be cleaned because it is removing impurities from the air.  They collect on the metal plates as opposed to being trapped in a filter.  This also means there are no filters to buy periodically.  They are a little costlier than other types of air cleaners to purchase but, over time, they are cheaper because you dont need to buy those filters and they dont have fans to burn up electricty.
