ozone and ions are two totally different things ...totally, ozone has awsome uses,and different uses than a simple ion genorater but will kill plants and human lung tissue,,,,ions are just charged dust particles , and if tha filter is just for dust ....awsome,, ALL intake air should go thru heppa filtration, short of that use an in room purifier, like yours.....no dust stuck to my stash...remember OZONE is danger...ion is fine
