The ionic breeze filters the dust and allergens in my home. I have one for every room. Maybe I even have two in each room. It is very helpful because it has stopped my frequent sneezing and eye watering. It also filters pet hair which is good because it does not end up around the house all over and in the air. We rarely have to clean it and it is very easy too clean to. You just get a normal paper towel, wet it, maybe with windex or something, then just slide it across the metal panels inside the machine three or four times and then its clean. It is also helpful because it have a blue indicator...
