More expensive to operate then ionic purifiers but cleaner air overall.
5 March 2013
Summary: I have had every type of air purifier from hepa to silent ionic purifiers. I would have to say ionic purifiers are great for you don't have to replace any filters but hepa trap more particles "dust, pollen etc." by moving more air. I have three of these purifiers and wouldn't go back to ionic purifiers again. I have found some discount web sites for replacement filters and filter rebuild kits to save money.
