Great product.
First time using this product. My daughter has allergies so we needed to purify her room. She is young and likes to play and knock over the large towers. She hasn't seem to bother this plugged in the wall.<br />It hasn't even been plugged in 24 hours and I can tell a huge difference. I will be purchasing more of this items for other rooms.<br />only 4 stars instead of 5 because it is not whisper quiet, but sound is not overwhelming.
Rating: 4 stars
