“I purchased three of them, I was told that I can use one per room. However it seems to only reach the areas that are close to the plug in (about 2 feet radius) and the rest of the room is still collecting dust. And I could be wrong but it seems to be accumulating faster in the other areas.”
“Still have dust and dog hair every where. Bought 3 of these things and I can't see where it makes any difference at all. I think it's a waste of money”
“I play six of them all over my house and honestly I have not seen any difference. I still have allergies or a sneeze cough and blow my nose a lot not much different since I plugged it in and it has been over a month any suggestions.”
“Purchased 3 and all of them have the blue light working - not sure how to gauge the effectiveness. No noticeable air quality or smell. No dust has collected on the devices.”
