The ionic breeze has been thoroughly tested, and does in fact do a very good job in trapping allergens flying through air. However, on a down side, there have been a few complaints that device causes headaches. Usually, these reports have come from individuals who have kept device in room in which they sleep. Thus, it is advised that unit not be placed in bedroom.

In addition to running quietly, unit is also praised for being very environmentally and economically friendly. Because you do not have to buy filters for device (the metal core is simply wiped clean about once a week) you will save money as well as reduce waste. Also, unit runs on only 10 watts a day; an impressively small number compared with other air filtration units.

The take home message is that ionic breeze quadra is both effective and economical. If you don't mind a little work in cleaning device every week, and you take precautions in its placement, it is surely worth $250 asking price.
