5 pcs Ionic Air Purifiers

This is my 3rd order,I love them,2 of the ones I ordered before these,started making a very loud noise,so I trashed them,not thinking I could have sent them back.Just hoping theses last longer

They are too tiny, about 1/4 the size presented in the advertising. Don't believe they can do what they are supposed to do in a space of square footage that you advertised. I have one in the master bedroom testing it out now. Hoping it works and I don't have to go thru the hassle of returning them and trying to get my money back. BJC

They arrived in a timely manner. They were even smaller than I expected. After the 2 to 3 weeks I've been using them, there does seem to be less dust particles in the air. Only issue is that on one of the units the USB port is loose and only works after moving the cord around. Then when u get it working, just a touch and it goes off again.
